Python Foundation--if and while

Encountered a lot of code, unable to find the cause of the problem:
     All the characters in the Python script can be displayed to see if there are any special characters.
       Text Editor notepad++, display all character views--display symbols--   display spaces and tabs
       Found the problem (alignment with a dot dot space, is the same as the previous lines of the alignment of the arrow indicated by the TAB key, is not matched, that is, the alignment of the code, mixed with the TAB key and Space:)
       
        
        
        Preferences:              languages, replace with spaces (Tab key):
        

# import Getpass getpass.getpass ("Password:")

' TypeError: ' >= ' not supported between instances of ' str ' and ' int ' character type inconsistent error int conversion data type
