包装超过80个字符的python doctest结果

Question

我试图将我的源代码保持在PEP8建议的80字符指南宽度之下,但是无法弄清楚如何包装结果长于80个字符的doctest.

一个愚蠢的例子:

def long_string():
    """
    Returns a string which is wider than the recommended PEP8 linewidth

    >>> print long_string()
    0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789

    """
    return '0123456789' * 10

我尝试了几种组合,包括使用# doctest: +NORMALIZE_WHITESPACE和尝试用换行符简单地换行.

刚想通了:

def long_string():
    """
    Returns a string which is wider than the recommended PEP8 linewidth

    >>> print long_string()
    01234567890123456789012345678901234567890123456789012345678901234567890\
12345678901234567890123456789

    """
    return '0123456789' * 10

希望能帮助别人.

Answer 2

正如davitenio和qris所建议的那样，我建议像这样使用#doctest: +ELLIPSIS指令。

>>> from test.test_ppp import MockForm
>>> form = MockForm(mock_file='no-errors.xlsx')
>>> form.get_languages(settings_default='English', survey_header=
... form.metadata['raw_data']['survey'][0])  #doctest: +ELLIPSIS
['Ateso', 'English', 'Luganda', ... 'Runyoro-Rutoro']
