How to change letters in a string entered by the user?

Question

I have a python question called the "Password modifier" where a user enters a password of their choice (ie mypassword ) and the program needs to change the following.

i becomes !
a becomes @
m becomes M
B becomes 8
o becomes .

Any suggestions?

Answer 1

You can use str.translate and str.maketrans

>>> s = 'mypassword'
>>> s.translate(s.maketrans('iamBo', '!@M8.'))
'Myp@ssw.rd'

Answer 2

You can also harcode the shifting letters. Answers below are better but you can go like:

new_pass = ''
for char in password:
    if char == 'i':
        new_pass += '!'
    elif char == 'a':
        new_pass +='@'
    elif char == 'm':
        new_pass +='M'
    .
    .
    .
    else:
        new_pass += char

Answer 3

I am familiar with this lab. The easiest approach is to use the replace() feature. Don't forget to use string concatenation for the "q*s" needed at the end of the modified password:

user_input = input()
string_append = "q*s"

user_input = (user_input.replace('i', '!').replace('a','@')
              .replace('m', 'M').replace('B', '8').replace('o','.'))

print(user_input + string_append)

 

Answer 4

What about using the replace method for each character?

>>> password = 'mypassword'
>>> password = password.replace('a','@')
>>> print(password)
myp@ssword

Answer 5

Try the following:

chars={'i': '!', 'a': '@', 'm': 'M', 'B': '8', 'o':'.'}
password = input("Your password: ")
for x in password:
    if x in chars:
        password=password.replace(x, chars[x])

print(password)

Answer 6

1.Setup initial replacement....

text = "iamBo"
repl = "!@M8."
trans = str.maketrans(text,repl)

2.Get the password....

password = input()

3.Print the password....

print(password.translate(trans))
