print ("11")
else:
print ("else")
input:

output:
11

Why???????

Answer 1

You want to write a or b have to be 1, right?

a==1 or b==1

Your condition instead means:

if a exists (!=0) or b==1

'if x' only checks if x - whatever it is - is not False. So any number != 0, any container with at least one item, any string with at least one sign in it (even space) will be True.
