how do i get assign variables to be used in other functions?
for example the age that the user inputs. how do i use that in both the function to get the age and the function to calculate 3*math.sqrt (age)

Edited 6 Years Ago by vegaseat: added code tags

In your main function when you call getUserAge() assign the return to a variable its self. If you want to use it in another function the you will need to have the function you want to use it in have a input parameter.

userAge = getUserAge()
def calThreeSqrtOfAge (userAge)

You have to pass the required arguments to an from your functions. Look at your modified code carefully ...
