New submission from Carl Anderson <[email protected]>:
Fraction works with a regular slash:
>>> from fractions import Fraction
>>> Fraction("1/2")
Fraction(1, 2)
but there are other similar slashes such as (0x2044) in which it throws an
error:
>>> Fraction("0⁄2")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/anaconda3/lib/python3.7/fractions.py", line 138, in __new__
numerator)
ValueError: Invalid literal for Fraction: '0⁄2'
This seems to come from the (?:/(?P<denom>\d+))? section of the regex
_RATIONAL_FORMAT in fractions.py
