I am trying to make a measurement machine with python, but when I enter the measurements it just goes on with the code, I want it to stop processing once I get a result, here is the code I have done so far:

I need it to stop after "print math.sqrt(int(h1)**2 + int(h2)**2)"

need = raw_input("What do you need to Use?")

if need == "pythagoras" or "Pythagoras":
    pythagoras = raw_input("What side do you Need?")

if pythagoras == "hypotenuse" or "Hypotenuse":
    h1 = int(raw_input("Known Side 1"))
    h2 = int(raw_input("Known Side 2"))

import math
print math.sqrt(int(h1)**2 + int(h2)**2)

Answer 1

Calling sys.exit will immediately terminate the execution of the program, like return does for functions:

import sys

...
print math.sqrt(int(h1)**2 + int(h2)**2)
sys.exit()

Answer 2

̶N̶o̶t̶ ̶n̶e̶e̶d̶ ̶i̶m̶p̶o̶r̶t̶ ̶s̶y̶s̶,̶ ̶w̶i̶t̶h̶ ̶e̶x̶i̶t̶(̶)̶ ̶c̶a̶n̶ ̶e̶x̶i̶t̶.̶

It's more clean if pass 0 argument (good exit):

sys.exit(0)
