if 'x' and 'y' in 'z':

Question

I'm making sort of a Q&A script in python. It gets raw_input, and sets it as theQuestion. I tried if 'var1' and 'var2' in theQuestion:, but it looks for either string, not both. Is there a way I can make this work in one 'if' statement? (not 'if x: if y: then z).

Answer 1

and is a logical AND, not a natural-language one. Therefore, your code gets interpreted as:

'var1' and 'var2' in theQuestion
True   and 'var2' in theQuestion # Since bool('var1') == True
           'var2' in theQuestion

You want to connect the two tests with a logical AND:

if 'var1' in theQuestion and 'var2' in theQuestion:

Alternatively, for large numbers of tests:

if all(k in theQuestion for k in ('var1', 'var2')):

Answer 2

How about:

if 'x' in z and 'y' in z:
