[Python] doctest: +NORMALIZE_WHITESPACE

[Pietro]

Ciao a tutti,

sto utilizzando le doctest per la mia documentazione... solo che il
NORMALIZE_WHITESPACE, mi funziona solo con le liste e non con i
dizionari...

in un file test.py ho scritto:

# test.py
"""
>>> a = range(9)
>>> a #doctest: +NORMALIZE_WHITESPACE
[0, 1, 2,
 3, 4, 5,
 6, 7, 8]
>>> z = {'a':0, 'b':1, 'c':2, 'd':3,}
>>> z #doctest: +NORMALIZE_WHITESPACE
{'a' : 0,
 'b' : 1,
 'c' : 2,
 'd' : 3}
"""

se lo eseguo con:

$ python2 -m doctest test.py -v
Trying:
    a = range(9)
Expecting nothing
ok
Trying:
    a #doctest: +NORMALIZE_WHITESPACE
Expecting:
    [0, 1, 2,
     3, 4, 5,
     6, 7, 8]
ok
Trying:
    z = {'a':0, 'b':1, 'c':2, 'd':3,}
Expecting nothing
ok
Trying:
    z #doctest: +NORMALIZE_WHITESPACE
Expecting:
    {'a' : 0,
     'b' : 1,
     'c' : 2,
     'd' :3}

Failed example:

     'b' : 1,
     'c' : 2,
     'd' :3}
Got:

1 items had failures:
   1 of   4 in test
4 tests in 1 items.

cosa sto sbagliando?

grazie a tutti per l'aiuto!
