What is a python third-party library?

In the Python language library, it is divided into Python standard library and Python third-party library. Python's standard library is the library that comes with Python by default when it is installed. Python's third-party libraries need to be downloaded and installed in the Python installation directory. Different third-party libraries have different installation and usage methods. They are called in the same way, and they all need to be called with the import statement.

For example, call the requests library. The requests library is not the standard library of Python. You need to call it before using it again. Enter import request
