In order to identify whether a Python file is valid or not proceed as follows:

  1. Open a command line from the path where your Python file exist.

    In the example screen shot above you can see that there is an error "TabError: inconsistent use of tabs and spaces in indentation" which shows that the Python file is not properly interpreted. The interpreter also gives you the line number with the issue.
    This means that you could encounter issues while running the analysis on this file.
  4. When there is no issue with the python file then you will have no error, see below screen shot
