Learn Python – Git Modules in Python- Basic and advance

In this article, we will discuss the Git module in the Python programming language, how users can use it in tasks of Python. We will additionally talk about how users can use git modules in conjunction with GitHub so that we can work on giant initiatives with different users. We will also analyze how to create a git repository, how to see all the challenge files’ history, how we can go lower back to when our project’s preliminary stage and how to add new documents and modifies them in the repository.

What Is Git?

Git module of Python language is a disbursed version manage system. A version control gadget is a set of tools used for tracking the past of a set of archives of the projects. Users can without problems shop the state of archives at any factor by means of instructing the Git model manage system. After this, the person can proceed to edit the archives of the project and keep the mission at any state. Saving the assignment at any cutting-edge kingdom is like maintaining a backup of the challenge directory. In the Git module, saving the country is referred to as making a commit.

Whenever a user makes a commit in the Git module, the person adds a commit message that explains all the changes made in that country of the project. Git module can exhibit all the history of adjustments and commits made with the aid of the person in the project. This characteristic of the git module simply helps the customers to determine out what work they have executed and seem to be in particular for all the bugs that crept into the systems.

By using git modules, users can also evaluate the documents of the initiatives with exceptional commits. Git module additionally allows the person to return any file or files back to the until now state of the mission with very little effort.

The dispensed version manage device is slightly specific from the model control system. The formerly version control system works by way of saving all the commits domestically on the user’s tough drive. This collection of commits on the local tough pressure of the user’s is recognized as a repository. But due to this, customers are no longer able to work with the group working on the identical codebase. As working with the team on the identical project, users want their repository to be saved on the platform the place all the other crew contributors can get right of entry to it. A Distributed model manipulate machine saves the repository on a chief server, which can be shared by means of many customers and developers. This also has the characteristic of file locking.

For Git modules, most of the users and builders use GitHub as a central repository, the place all people can access the file. GitHub is like a central place the place everyone can share the code, and all people can access that. The full repository is nonetheless saved at all the nearby repos even after using GitHub.

Basic Usage of Git Module

Till now, we recognize the Git module in general. This topic will talk about how users can begin working with Git modules on their nearby pc system.

Step 1: Creating a new repository

To begin working with Git module, users first need to enter their information. They have to set a username with the git configuration command.

$ git config -- global user.name " name of the user goes here "  
$ git config - global user.email "username@forexample.com"  

After the setup of the username, customers would want a repository to work in. Creating a Repository is very easy. Users can use the git initialization command in the directory:

$ mkdir sample  
$ cd sample  
$ git init  

Users can initialize the empty Git repository in / domestic / tmp / pattern /. git /

After developing a repository, users can search it on the Git module. The Git module command user makes use of the most regularly is the Git status:

$ git status  

This output suggests a couple of the data to the user, like on which branch they are on and that they have nothing to commit. Nothing to commit ability that there is no file in the listing that the Git module is now not conscious of.

And that’s how we create a repository.

Step 2. Add a new file to the Repository

Create a file in the repository that Git does not be aware of about it. Create the file sample.py the use of the editor, which has only a print declaration in it.

print ( ' Adding a New File ! ' )   

After this, if the consumer will run the Git popularity command again, they will see the special results:

$ git status  

After checking the new file, the Git module will inform the person that the file is untracked. That capacity Git is pronouncing that the specific file is no longer a section of the repository and is now not under model control. Users can restore this through including the new file to Git. Using the git add command for including the file to the Git module.

$ git add sample.py  
$ git status  

Now Git is conscious of the new file sample.py, and it will listing the file below adjustments to be committed. The addition of the file to the Git module transfers it into the staging area. This capacity users can now commit the file to the repository.

Making a Commit Changes

Whenever a User commits changes, they are telling the Git module to save this level of country of the file in the repository. Users can do it by means of the use of the commit command of the git module. The -m alternative in the command informs the git module to commit the following message. If the users do no longer use the -m whilst running the command, the Git module will open the editor for the customers to create the commit message. To commit the message user need to write the command like this:

$ git commit -m " creating sample.py "  
$ git status  

Users can now see that the commit command has returned a couple of information, most of it is no longer a great deal useful, but it does inform the consumer that only one file has modified because the consumer has solely introduced one file in the repository. The commit command also informs the easy hashing algorithm of the commit (775ca29).

After going for walks the git repute command again, it shows that the consumer now has a clean working directory, which skill that all the modifications in the file are now not committed to Git.

The Staging Area of the Git Module

Git module has a staging area, which is more often than not referred to as the index. The staging vicinity is the place the Git module keeps song of the change’s consumer wants to do in their next commit. Whenever the consumer runs the Git Add command, like above, where a new file sample.py was once moved to the staging area, this trade used to be shown in the git status. The file of the project was moved from the untracked area of the git module to the to be dedicated part of the output.

The staging place of the Git module indicates the specific content material of the file when the person run git add command. If the consumer modifies this again, the file will be visible on both the areas, staging and unstaging of the git popularity output.

At any stage of working with the git module on the file, which has already been committed once, there are three versions of the file available on which users can work:

One version is on the user’s hard drive that the user is editing.

Another version is stored by the Git module in the user’s staging area.

The third version is present in the repository of the file.

All of the three variations of the file can be special from one another. By moving the adjustments to the staging location of the users and then committing the files, they can carry again all these versions of the file into the sync.


The git reputation command in the Git module is very accessible, and users can use it most often. But sometimes, users would possibly locate out that there are couples of documents that are showing up on the untracked area of the git module, and they do no longer favor the git modules to see them. For that, the consumer can use a .gitignore file.

For example:

#Let's create a new Python file of the project in the same directory called example.py:  
Def get_example ( ) :  
return " cow "  

After this, adjust the sample.py file to encompass the example.py and call its function:

import example   
 example = example.get_example ( )  
print ( " Animal { } " .format (example) )  

Whenever the user imports a nearby module, the Python starts compiling the module into byte code and saves the file on their filesystem. In the Python2, after compiling the module into bytecode, it will keep the file in the structure example.pyc. But in the case of python3, it will generate a _pycache_ listing and keep the .pyc file in it.

For example:

After doing this, if the consumer runs the command of git status, they will see that particular directory existing in the untracked section. Users can also see that their example.py file is in the untracked section, however the modifications they made to sample.py are in the new section, which is recognised as “Changes no longer staged for commit”. This part capacity that the adjustments a user made previously have not been introduced to the staging area of the git module.

For example:

$ git status  

To add example.py sample.py documents to the repository, the person wishes to do the identical they did earlier.

For example:

$ git add example.py sample.py  
$ git status  

Now, the user need to commit the changes and ought to finish the easy – up:

$ git commit -m " add example module "   

whenever the user runs the git fame command, they will see _pycache_ listing like this:

$ git status  

if the person wants all the _pycache_ directory and its content material to be ignored, then they have to add a .gitignore file in their repository. This is a very simple process. Users have to edit the file in their chosen editor.

# .gitignore  

Then, users have to run the git status command, and they no longer see the _pycache_ listing and its content. Although the consumer will see the new .gitignore ! file.

For example:

$ git status  

The file .gitignore is just a regular textual content file, and this can be brought to the repository simply like the other everyday files.

For example:

$ git add .gitignore  
$ git commit - add " create .gitignore "   

There is one extra entrance in the .gitignore file, which is the listing that the consumer shop in their virtual environments. This directory is known as virtualenvs. The virtualenvs listing is typically known as env or venv.

Users can add these to their .gitignore documents of the project. By doing this, the directory or the archives of the task present in the repository will be ignored. And if there is no file or directory is present then, no motion will be done.

Users can also save a global .gitignore file in their domestic directory. This process is very easy and simple if the user’s editor uses to store the brief archives or makes a lower back – up files in the nearby directory of the pc system.

For example:

# .gitignore   
Venv /  
Venv.bak /  
env /  
env.bak /  
.cover /  

What user should not add to a Git Repository?

When the users are in the initial stage of working on any version manipulate tool, and most in all likelihood with the Git module. The consumer would choose to save each kind of file in the repository of the Git however this a mistake. Git module does have limitations and also security concerns due to which users face some limits on what type of archives and facts they can add to the git repository.

The fundamental rule of all version control systems is that the consumer need to only add supply files in the model manipulate structures and by no means add the generated documents to the version manipulate system.

The source file is any file that the user creates whilst typing in the editor. The generated archives are the archives that the pc creates while processing the supply files.

For example:

Sample.py is a source file, while

Sample.pyc is the generated file.

The motives for not involving the generated documents in the Git repository:

Storing generated files in the repository is a waste of space and time. The generated files can be created again, and it may need to be recreated in a different format. If user 1 is using IronPython or Cython, and user 2 is using Jython interpreter, then the .pyc files would be different from each other. And committing the one format of the .pyc file could create conflicts in the repository.

The generated filers are comparatively larger than the source files of the project. Adding the generated files in the Git repository means that all the other users and developers of the particular project also have to download the files and store them, even they do not need the files.

Another rule of the Git repository is that the user should commit the binary files with precautions and should avoid committing files of large size.

Git module repository does no longer save the full duplicate of each file of the venture the consumer commit. Instead, the repository makes use of the difficult algorithm, which is based totally on how distinctive following variations of the files. This reduces the extent of storage file needs. But this algorithm does no longer practice to the binary archives as the binary archives such as MP3 or JPG documents do no longer have correct difference tools. For binary files, the Git module repository has to keep the full file of the challenge every time the consumer makes the commit.

When the user is working on the Git module, or storing files on the GitHub repositories do no longer store the private records in the repository, whilst sharing it publicly.

Git Log

Git log is the command of the Git module. Git log is used to seeing the history of the commits made by using the user.

For example:

$ git log   

Users can see the history of commits made through the person in the git repository. All the commit message will show up in the order they had been made. The beginning of the commit will be identified by the word “commit” and after the easy hashing area of the commit. Git log command will furnish the history of each simple hashing areas.


This article has discussed the Git modules, version manipulate system, how to make commit in Git and its repository functions, policies of adding files and records in the repositories of the Git module and GitHub. The unique types of Git command like .gitignore, git log, git add, git status, etc., and their use in the files of task and directories.
