Python Tutorial - Looping your code back (to the beginning or middle) using a procedure

A quick tutorial on how to loop your code back to the middle or beginning using a procedure. This is useful if you want to reload / re-run the script, module or code block.

[@sadgallington7850]

You're literally a god my dude, you saved all my noobish code!. I wrote a giant if elif else code with a lot of shit, and I didn't know how to properly loop till I saw this video. Not even hours and hours of research did what your 6 min video did. Thanks... I REALLY apreciate it.

[@billal2731]

Good luck for your work ^^

Nice man, I got a task and thanks to you I did it!

[@enternamehere6686]

TL;DW
-Define (make a function) the program that you want to repeat or not repeat (depending on user input)
-Make a variable input at the end of the function you just made, preferably an integer input for simplicity
-Make either, 1 if statement and an elif/else, or make 2 if statements deciding whether the repeat variable was yes or no
-If the repeat variable was yes then put the function name under the corresponding if statement, and if the repeat variable was no then put an "exit()" under the statement
-Lastly, not under any function, call the function

Useful video! Thanks

thank youuuuuuuuuuuuuuu

[@godman1117]

Thanks you, very helpful script to know

[@thatsawesome.]

thank you!

[@xBZZZZyt]

This will crash if user repeats too many times because it is recursive.

[@tejaspro7128]

yeah!

[@NotMuj]

Thanks so much!

[@jogeshnanda7704]

Simple and Great... (Y)

[@danielpo5771]

Thank you...Gooooodd!!!!

[@kalengsarden3493]

thank sir

[@lukeliu4226]

sheesh moment

[@silver1340]

While this does work, doesn't it expose your program to Python's recursion limits?
Originally I was scripting in CMD and made heavy use of 'goto' commands, then switched to Python, did the exact same thing as in this video, but realized that Python does remember which functions were called, and if you continue to call, without ever using "return" or the like, you will hit recursion limit.

[@aloshie1]

crystal clear and helpful no 15minutes of messing with my head, straight to the point, thank you so much

[@abukmoha5092]

Thank you very helpful appreciate it 💖 🙏🏾👊🏾

[@azhanisyahputra9867]

This would only works if you were using only one def function. Otherwise it will loop like forever 😢

[@WhooseAGoose]

Doesn’t work 😐

[@skillerx79]

it does. watch out for indent. its important

[@florinalexandruciovica2526]

def main():
print("type one of the following : goat, wolf , cabadge").lower()
operator = input("What did the man chose?")
if operator == "goat":
print("excelent!")
elif operator == "wolf":
print("worng!")
elif operator == "cabadge":
print("worng!")
else:
print("WRONG!")
repeat = input("Would you like to try again?").lower()
if repeat == "yes":
main()
else:
print("bye")
exit()
main()
where am i wrong? is not coming back to start?

[@aspire_minister5426]

Repeat = input("Would you like to retry?").lower()
if Repeat == 'yes':
main()
else:
print('Thanks for playing')
exit()
main()
You need to make the text indent and define "main" at the start of where you want it to restart from.
#!/bin/python3
from random import randint
import time
import functools
import operator
import random
import math
print('Welcome to multiplication questions.')
ans=input('Are you ready (yes/no) : ')
if ans.lower() == 'yes':
start_time = time.time()
def main():
score = 0
# Game Logic
while True:
difficulty_setting = 2
difficulty_progression = math.floor(score/10)
overall_difficulty = difficulty_setting + difficulty_progression
number_list = []
for x in range(overall_difficulty):
value = random.randint(1,9)
number_list.append(value)
answer = functools.reduce(operator.mul, number_list, 1)
print('Multiply these numbers', number_list)
guess = int(input())
if guess == answer:
score = score + (1* overall_difficulty)
continue
else:
print('Game Over! The answer was', answer)
elapsed_time = time.time() - start_time
print('Your score was', score, 'in only', elapsed_time)
break

Repeat = input("Would you like to retry?").lower()
if Repeat == 'yes':
main()
else:
print('Thanks for playing')
exit()
main()
That is an example of a code I used.

[@invisibleinsociety]

​@@aspire_minister5426 man it still doesn't works :(
here is my code : ( it take an input from the user then he write a letter then the program tells the number ) :
############################
def main():
yeslist=["yes","y","YES","y","yeah","ok"]
name=input("enter your name:")
letter=input("enter a letter:")
if letter in name:
print(name.index(letter))
else:
print("something went wrong :(")
repeat=input("do u want to restart ? :").lower()
if repeat==yeslist:
main()
else :
print("ok, bye :(")
exit()
main()

Thank you for a clear and useful tutorial with no superficial talk only relevant stuff

[@Ron-rd5th]

I keep getting an error saying "yes" is not defined when I enter yes for restart

[@deeptiadval728]

you have to write
if restart=="yes"
main()

[@bynishant9616]

u cannot code noob

[@bynishant9616]

just like your dp u dumbfuck

[@deeptiadval728]

put "yes" in a variable

[@hamsahali4753]

Unleash your Tech ????

[@chickinuggit4487]

This is nice

[@zrhn4127]

thanks! If it weren't for this i'd still be stuck getting errors trying to loop with while and for. deserves a like and sub fam.

[@itsdezman]

Thank you for this video! I'm trying to get my script to repeat 10 times. How can I set a number for the number of times it repeats?

[@tejaspro7128]

Copy Paste your main code 10 times
SUPER SIMPLE

[@jorgemarinjaramillo221]

Justo lo que necesitaba gracias!! // exactly what I needed thanks!!
