python - What would be a compact way to return 1 if a variable is 0 and to return 0 if it is 1? -

how following made more compact (perhaps using booleans), given supplied integer variable?

indextag = 0 # or 1 1 if indextag == 0 else 0 

you use not:

not indextag 

which gives boolean (true or false), python booleans subclass of int , have integer value (false 0, true 1). turn integer int(not indextag) if boolean, why bother?

or subtract 1; 1 - 0 1, , 1 - 1 0:

1 - indextag 

or use conditional expression:

0 if indextag else 1 

demo:

>>> indextag in (0, 1): ...     print 'indextag:', indextag ...     print 'boolean not:', not indextag ...     print 'subtraction:', 1 - indextag ...     print 'conditional expression:', 0 if indextag else 1 ...     print ...  indextag: 0 boolean not: true subtraction: 1 conditional expression: 1  indextag: 1 boolean not: false subtraction: 0 conditional expression: 0
