Guide to Install Python on Ubuntu
Python is a powerful programming language that is widely used for various applications. In order to start programming in Python, you need to install it on your Ubuntu (Linux) system. This guide will walk you through the installation process step by step.
Step 1: Update Package Lists
Before installing Python, it is recommended to update the package lists on your system to ensure you have the latest versions of software available. Open a terminal and run the following command:
sudo apt update
Step 2: Install Python
To install Python on Ubuntu, you can use the package manager called
apt. Run the following command to install Python:
sudo apt install python3
This command will install Python 3, which is the latest version of Python. If you specifically want to install Python 2, you can use the following command:
sudo apt install python
Step 3: Verify Installation
Once the installation is complete, you can verify that Python is installed correctly by running the following command:
This command will display the version of Python installed on your system.
Step 4: Install Pip (Python Package Installer)
Pip is a package management system used to install and manage software packages written in Python. To install Pip, run the following command:
sudo apt install python3-pip
After the installation, you can verify that Pip is installed correctly by running the following command:
Step 5: Install Virtualenv (Optional)
Virtualenv is a tool used to create isolated Python environments. It allows you to install packages and dependencies specific to a project without affecting the system-wide Python installation. To install Virtualenv, run the following command:
sudo apt install python3-venv
Step 6: Create a Virtual Environment (Optional)
If you want to create a virtual environment for your Python projects, you can use the following command:
python3 -m venv myenv
This command will create a new virtual environment called “myenv” in the current directory.
Step 7: Activate the Virtual Environment (Optional)
To activate the virtual environment, run the following command:
After activating the virtual environment, any packages you install using Pip will be isolated to that environment.
Here are some useful commands related to Python installation and management:
|Starts the Python interpreter
|Runs a Python script
pip3 install package_name
|Installs a Python package
pip3 uninstall package_name
|Uninstalls a Python package
|Lists installed Python packages
|Deactivates the virtual environment
By following this guide, you have successfully installed Python on your Ubuntu (Linux) system. You can now start writing and running Python programs. If you want to create isolated Python environments for different projects, you can also use Virtualenv. Enjoy coding with Python!
