Hi,

I have used goto instruction a lot when I started to program in Basic ( an Amstrad CPC πŸ₯Ή). In this context goto had logic. But in modern languages like python I think it is a very bad idea:

  • Understand the logic is more complex
  • Functions and methods are a better and more powerfull alternative
  • It is dangerous: add or remove a new line of code could have bad consequences

Regards

i've found a good alternative is returning functions

eg. you have a function like this:

def cycle(func): while True: func=func()

then you start with cycle(main)

def main(): return intro

if __name__ == '__main__: cycle(main)

and then main returns the next function, and following functions return functions..

def intro(): if thisthing: return thisfunc if thatthing: return thatfunc

return is being used like goto
