The docstring docs actually allude to the problem, but not entirely clearly.
A couple of other stackoverflow threads here and here were helpful, but not easy to find given my own search criteria.
Here is my actual solution:
def remove_CRs(text):
r"""
>>> output = remove_CRs("line1 \r"
... "still line1\n"
... "now line2 \r"
... "more line2\r")
>>> print(output)
line1 still line1
now line2 more line2
"""
return text.replace('\r', '')
import doctest
doctest.run_docstring_examples(remove_CRs, globals())
Three things have changed from the original code snippet:
- The docstring had to be a raw python string.
- I had to use
print()
on the function output.
- I had to get over my own confusion with the difference between
\n
and \r
. (That one's on me.)
Hope this saves someone else the couple of hours I spent on this.
