Introduction
Python is a general-purpose and high-level programming language that can be used to build websites, software, and mobile applications. Python has many features that make it easy to read, write, and maintain the code. Python also supports new-age technologies and concepts such as Big Data, Machine Learning, Data Analysis, and Visualization. These are some of the reasons why Python is a popular and versatile choice for developing applications.

This will download a compressed file named Python-3.10.4.tgz in your current directory. You can then extract the file using the tar command:
tar -xvf Python-3.10.4.tgz
This will create a directory named Python-3.10.4 with all the files needed to install Python.
Installing Python
To install Python on Linux, you can use the RPM package manager that comes with most Linux distributions. RPM stands for Red Hat Package Management system, and it is used to install applications in Red Hat Enterprise Linux-based distributions such as Fedora, CentOS, and RHEL.
To install an RPM package, you need to use the rpm command followed by the name of the package. For example, to install the RPM package for Python 2.4.3 that we found from , we can use the following command:
sudo rpm -i python-2.4.3-46.el5_8.2.i386.rpm
The -i option tells the package manager that you want to install the file. You may need to enter your password to confirm the installation.
If you want to upgrade an existing package, you can use the -U option instead of -i. For example:
sudo rpm -U python-2.4.3-46.el5_8.2.i386.rpm
This will replace any previous version of Python 2.4 with the new one.
Checking Python Version
To check the version of Python installed on your Linux system, you can open a terminal window and enter the command python --version. Alternatively, you can enter the command python -V. This will display the version of Python that is associated with the python command.
If you have both Python 2 and Python 3 installed on your system, you may need to use python2 or python3 instead of python. For example:
python2 --version Python 2.7.18 python3 --version Python 3.10.4 Uninstalling Python
If you want to uninstall Python from your Linux system, you can use the rpm command with the -e option. This will erase the package from your system. For example, to uninstall the Python 2.4.3 package that we installed earlier, we can use the following command:
sudo rpm -e python-2.4.3-46.el5_8.2.i386
This will remove the package and any files associated with it. You may need to enter your password to confirm the removal.
If you want to uninstall all the packages related to Python, you can use the -qa option to list all the installed packages, and then use the grep command to filter out the ones that contain the word "python". For example:
sudo rpm -e $(rpm -qa grep python)
This will uninstall all the packages that have "python" in their name.
Conclusion
In this article, you learned how to download and install Python on Linux using the RPM package manager. You also learned how to check the Python version on your system, and how to uninstall Python if you no longer need it. Python is a powerful and versatile programming language that can be used for various purposes, such as web development, data analysis, automation, and more. By installing Python on Linux, you can enjoy the benefits of both a free and open-source operating system and a popular and high-level programming language.
FAQs
What is the difference between Python 2 and Python 3?
Python 2 and Python 3 are two major versions of Python that have some differences in syntax, features, and libraries. Python 2 is no longer supported by the developers as of January 1, 2020, while Python 3 is the current and future version of Python. Some of the main differences between Python 2 and Python 3 are:
Python 2 uses print as a statement, while Python 3 uses print as a function.
Python 2 uses raw_input to get user input, while Python 3 uses input.
Python 2 uses / for integer division, while Python 3 uses //.
Python 2 uses unicode and str as separate types, while Python 3 uses str for both text and binary data.
Python 2 has many built-in modules that are not available in Python 3, such as cPickle, cStringIO, and xrange.
How do I run a Python script on Linux?
To run a Python script on Linux, you need to have a file that contains Python code with a .py extension. You also need to make sure that the file has executable permissions by using the chmod command. For example:
chmod +x hello.py
This will make the file named hello.py executable by anyone. You can then run the file by using the following command:
./hello.py
This will execute the file in the current directory. Alternatively, you can use the python, python2, or python3 command followed by the name of the file. For example:
python hello.py python2 hello.py python3 hello.py How do I update Python on Linux?
To update Python on Linux, you can use the same method that you used to install Python, which is the rpm command with the -U option. This will upgrade the existing package to the latest version. For example, to update Python 3.10.4 to Python 3.10.5, you can use the following command:
sudo rpm -U python-3.10.5-1.i386.rpm
This will replace the old version of Python 3.10 with the new one. You can also use the yum or apt-get commands to update Python and its dependencies automatically. For example:
sudo yum update python sudo apt-get update python
These commands will check for any available updates for Python and install them.
How do I install Python modules on Linux?
To install Python modules on Linux, you can use the pip command, which is a package manager for Python. Pip allows you to install, update, and remove Python modules from online repositories such as PyPI (Python Package Index). To use pip, you need to have it installed on your system. You can check if you have pip by using the command pip --version. If you don't have pip, you can install it by using the command sudo apt-get install python-pip for Python 2, or sudo apt-get install python3-pip for Python 3.
To install a Python module using pip, you need to use the command pip install followed by the name of the module. For example, to install the module named requests, which is a library for making HTTP requests in Python, you can use the following command:
pip install requests
This will download and install the module and its dependencies on your system. You can then import and use the module in your Python code.
How do I create a virtual environment for Python on Linux?
A virtual environment is a way of isolating a specific version of Python and its modules from the rest of the system. This allows you to create different environments for different projects, without affecting each other or the system's Python installation. To create a virtual environment for Python on Linux, you can use the virtualenv command, which is a tool for creating and managing virtual environments.
To use virtualenv, you need to have it installed on your system. You can check if you have virtualenv by using the command virtualenv --version. If you don't have virtualenv, you can install it by using the command sudo pip install virtualenv.
To create a virtual environment using virtualenv, you need to use the command virtualenv followed by the name of the directory where you want to create the environment. For example, to create a virtual environment named myenv, you can use the following command:
virtualenv myenv
This will create a directory named myenv, which will contain a copy of Python and its modules. You can then activate the virtual environment by using the command source myenv/bin/activate. This will change your prompt to indicate that you are in the virtual environment. You can then install and use any Python modules that you need for your project.
To deactivate the virtual environment, you can use the command deactivate. This will return you to your normal system's Python installation.
