• The specific code is posted below , I can't find what went wrong , I thought it was the wrong class name, which should be lowercase , Finally, looking back, it turned out to be my own py The file name is also coverage.py.

import coverage
import unittest

if __name__ == "__main__":
    #  Instantiate objects 
    cov = coverage.coverage()
    #  To analyze 
    cov.start()```
