Here you assign the number 2 to 'a'

Here you assign whatever character(s) the user types to 'a'.
The fact that it looks like 2 doesn't change the fact that it
is really the character '2'. So you need to convert it to
a number using either int() or float()

a = int(input('-->'))
or
a = float(input('-->'))

I don't know, because you don't show us how you tried to
use float(), but if you apply it as shown above it
should work.
