CONTINUE COMMAND AND EXIT LINE

The Continue Command

The continue command stops executing code in the loop and starts at the top of the loop again. Essentially, we want to kick the user back to the original question.

EXAMPLE :

while True:

print("You are in a corridor, do you go left or right?")

direction = input("> ")

if direction == "left":

print("You have fallen to your death")

break

elif direction == "right":

continue

else:

print("Ahh! You're a genius, you've won")

NOTE :

The else statement refers to any input besides left or right (up or esc). Since the user is a winner, we do not want to use break or it would say they have failed.

EXIT COMMAND LINE

The previous code continues to loop even after the user has won. Let's fix that with the exit() command

EXAMPLE:

print("Let's play chutes and ladders. Pick ladder or chute.")

while True:

print("Do you want to go up the ladder or down the chute?")

direction = input("> ")

if direction == "chute"

print("Game over!")

break

elif direction == "ladder":

continue

else:

print("Game over!")

exit

print("Thanks for playing!")

ALL ABOUT WHILE LOOP

WHILE LOOP A while loop allows your code to repeat itself based on a condition you set. EXAMPLE : counter = 0 while counter < 10: print(counter) counter +=1 Infinite Loop You have to be really careful that you don't accidentally invoke an infinite loop! This is where the computer will loop code until the end of time. Without a break. Forever. This is just saying "count to 10 by 1 each time." to make the loop end. Don't forget, if your condition is a > then you might need to -= . This will subtract from the variable instead of adding to it. EXAMPLE : counter = 0 while counter < 10: print(counter) counter += 1

WHAT IS ELIF

What the elif is this? The elif command (which stands for 'elseif') allows you to ask 2, 3, 4 or 142 questions using the same input! This command must be in a certain place. You can have as many elif statements as you want, but they must go in between if and else and have the same indentation. The print statements in your elif command need to line up with the indent of the other print statements. EXAMPLE : print("SECURE LOGIN") username = input("Username > ") password = input("Password> ") if username == "mark" and password == "password": print("Welcome Mark!") elif username == "suzanne": print("Hey there Suzanne!") else: print("Go away!")

Automate! Automate!

Making this customizable 👉So how about making our search user customizable? In the code below, I have: Asked the user to input an artist (line 14) Tidied up their input (line 15) formatted the search URL as an fString that includes the artist (line 19) Here's tAutomate! Automate! We are so close. I can taste it, folks! Massive kudos on getting this far! Today's lesson, however, will work best if you have one of Replit's paid for features (hacker plan or cycles). Free plan Repls 'fall asleep' after a while. Automation kinda relies on the Repl being always on. If you have hacker plan or you've bought some cycles, then you can enable always on in the drop down menu that appears when you click your Repl name (top left).he code: This is important because when our repl is always running, it can keep track of time and schedule events. 👉 I've set up a simple schedule that prints out a clock emoji every couple of seconds. It works like this: Import schedule librar
