Python Going Back To Another Line Of Code

Is there a way for after multiple inputs down different paths, for it to continue at another line of code no matter what path has been followed? example : a = raw_input('1 or 2

Solution 1:

What you are looking for is a goto statement. Fortunately*, Python does not provide this feature. You can try using functions instead:

def print_chocolate():
    print("chocolate")

ifa== "1" :
    a = raw_input("3 or 4")
    ifa== "3"ora== "4" :
        print_chocolate()

ifa== "2" :
    a = raw_input("5 or 6")
    ifa== "5"ora== "6":
        print_chocolate()

Note:

You can save some lines of code by using logical operators (or, and).

Solution 2:

Wanting to use goto is often an indication to see if you can structure your code better: I agree with the Joran Beasley's comment that with good control structure you shouldn't need goto (many discussions on this see e.g. goto still considered harmful).

In my opinion, your program should reflect your intent and clearly divide responsibilities. I guess this is a toy example, but still there seem to be two things going on: getting and interpreting user input, and output. I think a clearer program, that avoids goto is as follows.

def UserInputDeservesChocolate():
    chocolate = Falsea= raw_input("1 or 2")
    ifa== "1" :
        a = raw_input("3 or 4")
        chocolate = a == "3"ora== "4"ifa== "2" :
        a = raw_input("5 or 6")
        chocolate = a == "5"ora== "6"return chocolate

ifUserInputDeservesChocolate():
    print ("chocolate")
