Docstring has inconsistent leading whitespace

In the following code:

def read_file(filename):
"""
>>> read_file('text.txt')
{'Donald Trump': [('Donald Trump', 'Join me live in Springfield, Ohio!\nLit!!\n', 1477604720, 'Twitter for iPhone', 5251, 1895)]}
"""


I get an error saying:

ValueError: line 4 of the docstring for __main__.read_file has inconsistent leading whitespace: 'Lit!!'


Any ideas what is causing this?

Answer

Escape all backslashes in the documentation string. That is:

\nLit!!\n

Should instead be:

\\nLit!!\\n'

Alternatively you could supply the docstring as a raw string and not worry about backslashes:

r"""
>>> read_file('text.txt')
{'Donald Trump': [('Donald Trump', 'Join me live in Springfield, Ohio!\nLit!!\n', 1477604720, 'Twitter for iPhone', 5251, 1895)]}
"""
