Loop in Python not working

I'm having trouble getting a while loop to work here. What I would like to do is have the program jump back to "please enter the word you with to translate" once it runs and provides the output.

When I have used while true and continue in what I believe are the proper places, it simply continues to print the output. of the word I'm translating. Hope that makes sense.

Listed below is the code I have working. The second chunk is where I add the while loop and run into issues.

def silly_alpha():
    print("Looks like we're going with the Impossible alphabet.")
    word_trans = input('Please enter the word you wish to translate: ')
    if word_trans.isalpha():
        for letter in word_trans:
            print(impossible.get(letter.lower()), end=' ')
    else:
        print("There's no numbers in words. Try that again.")

This is the problematic code

def silly_alpha():
    print("Looks like we're going with the Impossible alphabet.")
    while True:
        word_trans = input('Please enter the word you wish to translate: ')
        if word_trans.isalpha():
            for letter in word_trans:
                print(impossible.get(letter.lower()), end=' ')
                continue
        else:
            print("There's no numbers in words. Try that again.")
            continue

continue applies to the closest loop and allow to skip next instructions in this loop.

So your first continue applies to for, as it s the last instruction of the loop, it as no effect.

You second continue applies to while True, as it s the last instruction of the loop, it as no effect.

What you are looking for is break which terminates the closest loop. In your case, the while True I suppose.

So remove the first continue and replace the second by a break.

To have it repeat the loop, and accept a new word to translate, you simply need to remove those continue statements. I tested this in IDLE and it works just fine.

def silly_alpha():
    print("Looks like we're going with the Impossible alphabet.")
    while True:
        word_trans = input('Please enter the word you wish to translate: ')
        if word_trans.isalpha():
            for letter in word_trans:
                print(impossible.get(letter.lower()), end=' ')
        else:
            print("There's no numbers in words. Try that again.")

However, you now have an infinite loop. You may want to consider some way of allowing the user to enter a command that will terminate the loop. Perhaps something like:

def silly_alpha():
    print("Looks like we're going with the Impossible alphabet.")
    while True:
        word_trans = input('Please enter the word you wish to translate, "x" to cancel: ')
        if word_trans == 'x':
            print('Exiting translation...')
            break
        elif word_trans.isalpha():
            for letter in word_trans:
                print(impossible.get(letter.lower()), end=' ')
        else:
            print("There's no numbers in words. Try that again.")
