Question

I use the regex [,;\s]+ to split a comma, space, or semicolon separated string. This works fine if the string doesn’t have a comma at the end:

>>> p=re.compile('[,;\s]+')
>>> mystring='a,,b,c'
>>> p.split(mystring)
['a', 'b', 'c']

When the string has a comma at the end:

>>> mystring='a,,b,c,'
>>> p.split(mystring)
['a', 'b', 'c', '']

I want the output in this case to be [‘a’, ‘b’, ‘c’].

Any suggestions on the regex?

Try:

str = 'a,,b,c,'
re.findall(r'[^,;\s]+', str)
