As with Command Prompt, if PowerShell indicates that Python is not recognized, ensure that Python is installed and that the PATH variable is correctly configured.

Verifying Python Version in Python Interpreter

Another method to check your Python version is by launching the Python interpreter itself. Here’s how:

  1. Open Command Prompt or PowerShell.
  2. Type `python` and press Enter. This will take you into the Python interactive shell.
  3. Once in the shell, you can check the version by executing:

python
import sys
print(sys.version)

  1. Press Enter, and it will display detailed version information, including the version number and additional build details.

To exit the Python interpreter, type `exit()` or press `Ctrl + Z` followed by Enter.

Using Python Scripts

You can also create a simple Python script to check the version programmatically. Here’s a sample script:

python
# check_version.py
import sys

print(“Python version”)
print(sys.version)

  1. Save this code in a file named `check_version.py`.
  2. Open Command Prompt or PowerShell.
  3. Navigate to the directory where the script is saved using `cd` command.
  4. Run the script by typing:

python check_version.py

This will output the Python version in the same way as the previous methods.

Checking Python Version in Anaconda Prompt

If you are using Anaconda, you can check your Python version using the Anaconda Prompt:

  1. Open the Anaconda Prompt from your Start menu.
  2. Type the command:

python –version

  1. Press Enter, and the version will be displayed.

You can also run the Python interpreter within Anaconda by typing `python` to further explore the version details as mentioned earlier.

Common Issues and Troubleshooting

If you encounter issues while checking the Python version, consider the following:

  • Python Not Found: If you receive an error stating that Python is not recognized, ensure that Python is installed correctly and that the PATH variable includes the Python installation directory.
  • Multiple Versions: If you have multiple versions of Python installed, use `py` to specify which version to check:

py -3.8 –version

  • Environment Conflicts: If using virtual environments, activate the environment before checking the version to see the specific version installed in that environment.

By following these methods, you can efficiently verify the version of Python installed on your Windows machine.

I’m Leonard a developer by trade, a problem solver by nature, and the person behind every line and post on Freak Learn.

I didn’t start out in tech with a clear path. Like many self taught developers, I pieced together my skills from late-night sessions, half documented errors, and an internet full of conflicting advice. What stuck with me wasn’t just the code it was how hard it was to find clear, grounded explanations for everyday problems. That’s the gap I set out to close.

Freak Learn is where I unpack the kind of problems most of us Google at 2 a.m. not just the “how,” but the “why.” Whether it's container errors, OS quirks, broken queries, or code that makes no sense until it suddenly does I try to explain it like a real person would, without the jargon or ego.
