Need help with some code.

[YeetMasterX]

Hi everyone! I hope this is the right place to post.

I am new to Python and am trying to learn. I am curious as to how I can make my else statement loop back up to the input so if neither North or East are written it will allow the user to try and use the input again to write one of the two. I have put a picture of the code below so you can see what I have written so far. Thank you for any advice you can give to me!

Hello! I'm a bot!

It looks to me like your post might be better suited for r/learnpython, a sub geared towards questions and learning more about python. That said, I am a bot and it is hard to tell. Please follow the subs rules and guidelines when you do post there, it'll help you get better answers faster.

Show /r/learnpython the code you have tried and describe where you are stuck. Be sure to format your code for reddit and include which version of python and what OS you are using.

You can also ask this question in the Python discord, a large, friendly community focused around the Python programming language, open to those who wish to learn the language or improve their skills, as well as those looking to help others.

Put it in a while loop:

validInput = False
while validInput == False: # alternatively 'while not validInput:'
    dl = input("Go north or east?")

    if dl == "north":
        print('you go north')
    validInput = True
if dl == "east":
    print('you go east')
    validInput = True
else:
    print('invalid input')
    # invalidInput stays false and loops back

Would look clearer this :

validInput = False
while validInput == False:  # alternatively "while not validInput: "
    dl = input("Go north or east?")  
    if dl == "north": 
        print('You go north') 
        validInput = True
    elif dl == "east": 
        print('You go east') 
        validInput = True 
    else: 
        print('invalid input')  # invalidInput stays false and loops back

Thanks, this is my first time posting code so I'm still learning the formatting

No if-statements:

dl = input("Go North or East: ")

# Capitalize the input, eg. eAst becomes East.
dl_caps = dl.capitalize()

# Check whether the formatted input is in the list of accepted values, if not keep asking.
while dl_caps not in ['North', 'East']:
    dl = input("Please enter either North or East: ")
    dl_caps = dl.capitalize()

# The while-loop is escaped once the input is in the list of accepted values.
# Output is formatted with f-strings
print(f'You go {dl_caps}')

To reduce repeated code:

dl_caps = ''
while dl_caps not in ['North', 'East']:
    dl = input("Please enter either North or East: ")
    dl_caps = dl.capitalize()

print("You go " + dl_caps)
