 Question: How can one check the Python version in both Windows and Linux and what are the various solutions available?

Answer:

In both Windows and Linux, there are multiple ways to check the Python version installed on your system. Here, we'll discuss several solutions for each operating system.

Windows:

1. Command Prompt:

   • Open the Command Prompt.
   • Type the following command and press Enter:

     css
     python --version
     

     or

     python -V
     

   Example:

   less
   C:\> python --version 

2. Python 3.9.1

3. PowerShell:

   • Open PowerShell.
   • Enter the following command and press Enter:

     css
     python --version
     

     or

     python -V
     

   Example:

   lua
   PS C:\> python --version

4. Python 3.9.1

Linux:

1. Terminal:

   • Open the terminal.
   • Type the following command and press Enter:

     css
     python --version
     

     or

     python -V
     

   Example:

   css
   $ python --version 

2. Python 3.9.1

3. Alternative Commands:

   • Some Linux distributions use python3 instead of python. To check the version for Python 3, use:

     css
     python3 --version
     

     or

     python3 -V
     

   Example:

   css
   $ python3 --version 

4. Python 3.9.1

5. Checking through Package Manager:

   • Depending on the package manager used (e.g., APT, YUM), you can query for the installed Python version.
     • For APT (Debian/Ubuntu):

       css
       apt list --installed | grep python3
       

     • For YUM (Red Hat/CentOS):

       perl
       yum list installed | grep python3
       

   Example (APT):

   css
   $ apt list --installed | grep python3 

6. python3/now 3.9.1-1 amd64 [installed, ...]

These methods provide different ways to check the Python version on both Windows and Linux, ensuring flexibility based on user preferences and system configurations.
