$ sudo apt update && sudo apt upgradeThis command will update the package list and upgrade the system packages to their latest versions.
2. Install Python
Ubuntu Server comes with Python pre-installed, but it might not be the latest version. To install the latest version of Python, execute the following command:
$ sudo apt install python3This command will install Python 3 on your machine. You can check if Python is installed by executing the following command:
$ python3 --versionThe output should show the version number of Python installed on your machine.
3. Install Pip
Pip is a package manager for Python that allows you to install and manage Python packages. To install Pip, execute the following command:
$ sudo apt install python3-pipThis command will install Pip for Python 3. You can check if Pip is installed by executing the following command:
$ pip3 --versionThe output should show the version number of Pip installed on your machine.
4. Install Virtual Environment
Virtual Environment is a tool that allows you to create isolated Python environments. It is useful when you are working on multiple projects with different dependencies. To install Virtual Environment, execute the following command:
$ sudo apt install python3-venvThis command will install Virtual Environment for Python 3.
5. Create a New Virtual Environment
To create a new Virtual Environment, execute the following command:
$ python3 -m venv myenvThis command will create a new directory named myenv in the current directory, which will contain a fresh Python installation and Pip. You can replace myenv with any name of your choice.
6. Activate the Virtual Environment
To activate the Virtual Environment, execute the following command:
$ source myenv/bin/activateThis command will activate the Virtual Environment, and your terminal prompt will change to indicate that you are now using the Virtual Environment.
