I have the following:
>>> myString = "has spaces"
>>> first, second = myString.split()
>>> myString = "doesNotHaveSpaces"
>>> first, second = myString.split()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: need more than 1 value to unpack
I would like to have second
default to None
if the string does not have any white space. I currently have the following, but am wondering if it can be done in one line:
splitted = myString.split(maxsplit=1)
first = splitted[0]
second = splitted[1:] or None
May I suggest you to consider using a different method, i.e. partition
instead of split
:
>>> myString = "has spaces"
>>> left, separator, right = myString.partition(' ')
>>> left
'has'
>>> myString = "doesNotHaveSpaces"
>>> left, separator, right = myString.partition(' ')
>>> left
'doesNotHaveSpaces'
If you are on python3, you have this option available:
>>> myString = "doesNotHaveSpaces"
>>> first, *rest = myString.split()
>>> first
'doesNotHaveSpaces'
>>> rest
[]
