Making my password generator only allow certain symbols

Question

incorrectPassword= True
while incorrectPassword:
    password = input("type in your password: ")
    if len(password) < 8:
        print("your password must be 8 characters long")
    if len(password) >24:
        print("Your password must be shorter than 24 characters")
    elif not any(i.isdigit() for i in password):
        print("you need a number in your password")
    elif not any(i.isupper() for i in password):
        print("you need a capital letter in your password")
    elif not any(i.islower() for i in password):
        print("you need a lowercase letter in your password")
        incorrectPassword = False

How can I only allow certain characters (like !, $, %, ^, &, *, (, ), -, _, = or +) as needed input?

Thou shalt not limit the number of characters in passwords nor limit the symbols allowed. — Klaus D., Oct 05 '17 at 09:31

you can simply use

elif " " in password:
    #print error

or use Python's re package to define what characters are allowed in your password

I would use regex, but to do it in a similar fashion to your other tests:

any(i not in '!$%^&*()-_=+' for i in password)
