Python 3.4 gives error to this statement. This is o print the cartesian product for fuzzy logic operations.
print(f'The size of the relation will be: {len(self)}x{len(other)}')
I'm trying to perform the union, intersection and difference operations on fuzzy set.
python 3.4 does not support f-strings You could at emulate them if needed :
def f(s):
return s.format(**globals())
answer = 'CRICKET'
print(f('FOOTBALL OVER {ans}'))
Edit: Its better to use .format as this wouldn't work directly for len(something)
