如何将变量打印为字符串形式的输入长度？

Question

my task is when I type 'z' i get the outcome of 'w'.

This works.

However, if I input 'zzzz' only a single 'w' is outputted.

My question is how can I print 'w' for the number of times I enter z.

I am relatively new to StackOverflow. I'm sorry if I have broken any rules or my question is not correctly phrased.

z='w'
while True:
    plaintext=input('enter a word to get its ciphertext')            
    i=list(plaintext)
    print (i)
    if 'z' in plaintext
        print("w")

Answer 1

You are overcomplicating it. The variable you get from input() is a string. Simply use str.replace() .

while True:
    plaintext = input('enter a word to get its ciphertext')
    plaintext_rep = plaintext.replace('z','w')
    print(plaintext_rep)

Answer 2

Try looping through the text to get all of the letters

z='w'
while True:
    plaintext=input('enter a word to get its ciphertext')
    i=plaintext

    for letter in i :
        if(letter == 'z'):
            print ('w')
