python - doctest 预期为 True，得到 True

Question

doctest 很难控制。我遇到过这样的问题

函数

from collections import namedtuple

Match = namedtuple('Match', ['token_string', 'normalised_token',
                     'brand_name', 'brand_id',
                     'score'])


def make_match(tokens, normalised, brand, score):
"""
Examples:
>>> make_match('Jack Jones','JackJones',('Jack Jones','X023'),0.6)==Match('Jack Jones','JackJones','Jack Jones','X023',0.6)
True 
>>> make_match('Jack Jones','JackJones',('Jack Jones','X023'),0.6)==('Jack Jones','JackJones','Jack Jones','X023',0.6)
True
>>> match=make_match('Jack Jones','JackJones',('Jack Jones','X023'),0.6)
>>> match.token_string=='Jack Jones'
True
"""
return Match(token_string=tokens,
         normalised_token=normalised,
         brand_name=brand[0],
         brand_id=brand[1],
         score=score)

但出现错误

Failed example:
make_match('Jack Jones','JackJones',('Jack Jones','X023'),0.6)==Match('Jack Jones','JackJones','Jack Jones','X023',0.6)
Expected:
    True 
Got:
    True

1 项失败:

难道 Expected 没有完全匹配 Got 吗？ 非常感谢 1 of 4 in utilization.make_match 测试失败 1 次失败。

Answer 1

您在指定预期返回值的行上有尾随空格，因此 doctest 实际上是将字符串 "True " 与 True 的实际返回值进行比较。
