测试:我如何查明预期产出和实际产出之间的差别?
原标题:Doctest: How can I identify differences between expected and actual output?

在下文中,预期产出和实际产出都相同。 我确信,有一些白天空间错误,因为当我能够打上<条码>,挪威MALIZE_WHITESPACE时,测试是成功的。 是否有另一条旗帜可以帮助用户在这种白色空间错误的位置上三角?

"""
>>> df  # doctest:-NORMALIZE_WHITESPACE
              Open
Date
2021-05-17  126.82
"""

import pandas as pd

df = pd.DataFrame({ Date : [ 2021-05-17 ],  Open : [126.82]}).set_index( Date )

if __name__ == "__main__":
    import doctest
    doctest.testmod()
Failed example:
    df  # doctest:-NORMALIZE_WHITESPACE
Expected:
                  Open
    Date
    2021-05-17  126.82
Got:
                  Open
    Date
    2021-05-17  126.82
