Initializing/Changing Variables
I am currently working on a program for a learning video game for students. The scenario right now is that they see a traffic light blinking incorrectly and are supposed to input appropriate timing constraints for the light. For now I have the lights blinking on a timing loop where two are simply invisible if the other is on.
I want to give the students the option to change the value of the variable controlling these lights, but I do not know how to initialize a variable to one value and then be able to change it later without it conflicting with the initialization statement. Can anyone provide any tips on how to start with a variable at one value and then be able to give the user control to change it if they want without being reset by the first initialization statement? Thank you - Jassel41 |

You can modify a variable within a function by using the global keyword. Here pressing the spacebar modifies a variable and then prints it.
Code:
import viz import vizact viz.go() var = 1 def addTwo(): global var var += 2 print var vizact.onkeydown(' ',addTwo) |
