Setting environmental variables in python

✅ Purpose of Adding Python to System Environment Variables

1. Run Python from Any Command Line Location

• When Python’s installation directory is added to the PATH, you can run python or python3 from any folder in Command Prompt or PowerShell.
• Without it, you'd need to navigate to the Python installation directory every time.

2. Enable Python Scripts and Tools Globally

• Tools like pip, virtualenv, or other Python-based CLI utilities can be run directly.
• Example: pip install requests works globally if Scripts folder is in PATH.

3. Support for IDEs and Build Tools

• Some IDEs (like VS Code or PyCharm) and build systems rely on the system PATH to locate Python.
• Ensures smoother integration and fewer configuration issues.

4. Avoid “Python Not Found” Errors

• If Python isn’t in the PATH, you’ll get errors like:

  'python' is not recognized as an internal or external command

The Spyder IDE does not directly rely on the system PATH variable to locate Python. Instead, it uses the Python interpreter from the environment in which Spyder is installed—typically a Conda environment or a standalone installation.

 STEP-1

• Find the location of the Python File

STEP-2

Copy the directory of the .exe file and scripts folder where pip lies

C:\Users\karth\AppData\Local\Programs\Python\Python313

C:\Users\karth\AppData\Local\Programs\Python\Python313\Scripts

STEP-3

Go to Environmental variables --> Under system variables ->Click Path-> Edit 

STEP-4

click New-> Paste the path of python and scripts folder and click ok as shown below

STEP-5

To verify, open the command prompt and run python --version
