Hello Folks,

Thanks for the hints.
Please, see below, a new version. What do you think
about this new version?

Hoffmann
ps: The new version:

#!/usr/bin/python

import math
    
print '''This program calculates the lenght of the
hypotenuse of a right triangle
    given the lenghts of the two legs as
parameters.\n'''
    
leg1 = input('Enter the first leg of the triangle: ') 
leg2= input('Enter the second leg of the triangle: ') 
 

def hypotenuse(x, y):
    result = math.sqrt(x**2 + y**2)
    return result

result = hypotenuse(leg1, leg2)

print 'The hypotenuse of the triangle is', result
