Hi there, I'm a real newbie to python so sorry if this is a stupid question or if I don't fully get your answer, no hate please!
I'm trying to write a small program to use when calculating differential equations bu using Euler's step method, don't worry if you don't know what that is, it's not important. My code looks like this:
#!/usr/bin/python3.3 -tt import sys def main(): x = float(input("Ange x - värde: ")) y = float(input("Ange y - värde: ")) print ("(",x,",",y,")") h = float(input("Ange steglängd: ")) limit = float(input("Till vilket x - värde önskas gå: ")) while x < limit: a = (2 * x) + y y = (a * h) + y x = x + h print ("(",x,",",y,")") main()
This works FINE, but what I'd really like to be able to to is for the user to be able to enter (via input) a function for the variable a, instead of me having to define it in the very code of the program. Is there a way of doing this?
Thanks for any help! (BTW the language in the code is Swedish)
