Where is the pip command executed?

The pip command can be executed on the command line or in a script. Detailed instructions: 1. Command line (CLI), enter the pip command in the Windows command prompt, PowerShell, or the terminal of Unix/Linux/macOS; 2. Script, you can call pip in your Python script. You can also install packages using the built-in functions of Python's package manager pip. Starting from pip10.0.0, it is recommended to use the "pip._internal.utils" module.

Operating system for this tutorial: Windows 10 system, Python version 3.11.4, Dell G3 computer.

The pip command can be executed in the command line (CLI) or in a script.

1. Command line (CLI): Enter the pip command in the Windows command prompt (CMD), PowerShell, or the Unix/Linux/macOS terminal (Terminal). For example, pip install requests.

2. Script: You can call pip in your Python script. For example, you can use the subprocess module to call pip. For example:

import subprocess  
import sys  
  
def install(package):  
    subprocess.check_call([sys.executable, "-m", "pip", "install", package])  
  
install('requests')

This code will execute pip install requests in your Python script.

In addition, you can also use the built-in functions of Python's package manager pip to install packages. For example:

import pip  
  
pip.main(['install', 'requests'])

Note: Starting from pip 10.0.0, it is recommended to use the pip._internal.utils.cli module instead of using pip.main() directly. For example:

from pip._internal.utils.cli import subprocess  
  
subprocess.check_call([sys.executable, '-m', 'pip', 'install', 'requests'])

All of the above methods can execute pip instructions in your Python script.
