Share a simple way to check pip version

Easy way to view pip version sharing

When using Python to develop projects, we often use pip to manage and install required third-party packages. However, sometimes we may need to check the current version of pip to determine whether an upgrade or other operation is needed. This article will share several easy methods to check the pip version, and attach specific code examples.

Method 1: Use the command line
Enter the following command on the command line to view the version of pip:

pip --version

Sample output:

pip 20.1.1 from /usr/local/lib/python3.8/dist-packages/pip (python 3.8)

Method 2: Use Python script
We can also write a Python script to check the pip version. The following is a simple sample code:

import pip

def get_pip_version():
    return pip.__version__

if __name__ == '__main__':
    print(get_pip_version())

After running this script, the current pip version number will be output.

Method 3: Use the sys module
The sys module is one of the standard modules built into Python. It provides access to interpreter-related functions and variables. We can use the sys module to obtain pip version information. The following is a sample code:

import sys

def get_pip_version():
    return sys.modules['pip'].__version__

if __name__ == '__main__':
    print(get_pip_version())

After running this script, you can also get the version number of pip.

To sum up, we can check the pip version through the command line, Python script or using the sys module. These methods are very simple and very convenient to use. In daily development, knowing the current pip version is very helpful for project dependency management, so that upgrades or other operations can be performed in a timely manner to ensure the stability and reliability of the project.
