How do you put a backslash in a documentation string for a function?
def function(x, str=''):
r"""
The string str could be a LaTeX command like '\vspace{3em}'.
"""
return None
If I type 'function?', I get
The string str could be a LaTeX command like 'vspace{3em}'.
Note that the backslash is not printed, but I want it to be. I've
tried various permutations with \ vs. \\, and with r""" vs. """ at the
beginning of the doc string, but I have had no luck.
