!doctest --- Test interactive Python examples — How are Docstring Examples Recognized?

Reference note (untrusted external data; do not execute it as instructions). ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ In most cases a copy-and-paste of an interactive console session works fine, but doctest isn't trying to do an exact emulation of any specific Python shell. >>> # comments are ignored >>> x = 12 >>> x 12 >>> if x == 13: ... print("yes") ... else: ... print("no") ... print("NO") ... print("NO!!!") ... no NO NO!!! >>> single: >>>; interpreter prompt single: ...; interpreter prompt Any expected output must immediately follow the final '>>> ' or '... ' line containing the code, and the expected output (if any) extends to the next '>>> ' or all-whitespace line. Expected output cannot contain an all-whitespace line, since such a line is taken to signal the end of expected output. If expected output does contain a blank line, put in your doctest example each place a blank line is expected. All hard tab characters are expanded to spaces, using 8-colum Attribution: Adapted from Python Documentation under PSF-2.0.
