This article brings you a detailed introduction (code example) about the sys module in Python. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Command line parameter List, the first element is the path of the program itself
Return all Imported module list
Get the exception class currently being processed, exc_type, exc_value, exc_traceback currently processed exception details

Get the version value of the Python interpreter, in hexadecimal format such as: 0x020403F0
Get the version information of the Python interpreter
The maximum Int value
The largest Unicode value
Returns the module field imported by the system, the key is the module name, and the value is the module
Returns the search path of the module, using the value of the PYTHONPATH environment variable during initialization
Returns the operating system platform name, which is useful when writing cross-platform applications.

Python version information, for example: (2, 7, 6, 'final', 0), 'final' means final, and 'candidate' means candidate, indicating version level and whether there is a subsequent release
