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
