import sys

def Log(msg):
    print('Print Message: '+msg+' ,File: "'+__file__+'", Line '+str(sys._getframe().f_lineno)+' , in '+sys._getframe().f_code.co_name)

if __name__ == '__main__':
    Log('hello') # Print Message: hello ,File: "i.py", Line 4 , in Log

The Log function is a re-encapsulation of print, which can display the script name, line number and function name of the error program.

among them,

• sys._getframe().f_lineno: current line number, int type
• sys._getframe().f_code.co_name: current file name string type

The function is executed as follows:

Print Message: hello ,File: "i.py", Line 4 , in Log
