Currently having trouble with breaking this for loop. I want to break it if the variable is not found in this list so it can move two another for loop. It expects an indented block for the top of the for loop, but if I change the position of the break or of the start of the for loop, it doesn't work. Help!

while cyclenumb <= 10000:

    for x in userpassword[k]:
        for z in lowercaselist:
            if x in z:
                newpasswordlist.append(z)
                k +=1
                break
        else:

    for x in userpassword[k]:
        for z in uppercaselist:
            if x in z:
                newpasswordlist.append(z)
                k +=1
                break
        else:

You'll need to break out of each loop separately, as people have mentioned in the comments for your question, break only stops the loop which it's in

for x in userpassword[k]:
    for z in lowercaselist:
        if x in z:
            newpasswordlist.append(z)
            k +=1
            break
   
     if x in z: # added an extra condition to exit the main loop
        break

You'll need to do this for both loops

If you want to break out of the while loop as well, then you can add if x in z: break in that loop as well.
