The program below contains different versions of a Python block that asks the use for 2 integers, the second of which must be different from 0. The block then divides the first number by the second and prints the ratio as a float.
# Different options for a robust input

y = int( input( "Please enter an integer different from 0: " ) )
while y == 0:
y = int( input( "0 is not a valid input. Please reenter: " ) )
print( "%d / %d = %1.2f" % ( x, y, x/y ) )
