How to install the sys library in PyCharm?

In PyCharm, the sys library is built-in to Python and does not require a separate installation. Simply import the sys module into your Python code to access the functions provided by this library.

You can import the sys module in your code file by adding the following line:

import sys

After that, you can then use the functions and properties in the sys module. For example:

print(sys.version)  # 打印 Python 解释器的版本信息

Please note that the sys module is one of Python’s standard libraries, typically already installed in your Python environment by default and requiring no additional installation.
