Upgrading Python packages using Pip

When was the last time you updated a Python package installed via Pip? Most users tend to forget that these Python packages also need to be updated manually since just updating the system repository does not work for the packages.

1. List outdated Python software packages

Before planning to update any software packages, we must first list the outdated software packages, and you can choose the ones you want to update. packages, since most people won't want to update their entire package repository at once.

To list obsolete Python packages, you just need to combine the ​​pip​​ command with the ​​list​​ option, ​​ The --outdated​​ flag can be used together, as shown below:

pip list --outdated

##outdated packages

pip install package_name -U

​anime-api​​ to the latest version, so I will use the following command to upgrade:
