Check if space is in a string

Question

I'm composing a program that checks whether the string is a single word. For what reason doesn't this work and is there any better method to check if a string has no spaces/is a solitary word. 

' ' in word == True

Answer 1

The == outweighs in, so you're really trying word == True. 

>>> w = 'ab c'

>>> ' ' in w == True

1: False

>>> (' ' in w) == True

2: True

However, you don't require == True by any means. in the event that requires [something that evalutes to True or False] and ' ' in word will evalute to True or False. Thus, if ' ' in word: ... is okay:

>>> ' ' in w

3: True
