Hi! On school we got exercise to calculate how much the length of substance grow when we know original length and temperature change.
So,the case goes that i have value temperature coefficient of different substances and i have to multiply them. I'd like to it without doing several condition statements. I tried to do a class and function but it didn't work out.
Here's the code, and i don't have any clue how to finish it. It should calculate
like aluminium*1meter*1celsius and print out answer without using condition statements, but is there a way to do it?
#-*- coding: cp1252 -*- aluminium = 0.000023 concrete = 0.000012 silver = 0.000019 gold = 0.000014 copper = 0.000017 glass = 0.000008 a = raw_input("enter substance: ") l = float(raw_input("give original length: ")) t = float(raw_input("how much the temperature changes: ")) answer = a*l*t print'length changes', l, 'meters'
