如何在Python 3x中格式化字典键

Question

I am trying to format the dictionary key so that I can ask the user for the value and add that to the dictionary. so far my dictionary looks like this:

{'admin': ' '}

Expected output:

name: admin
admin's password: admin

Code:

new dictionary = {'admin': 'admin'}

def example():
        name= input("name: ")
        #no value yet for the input key
        value = ""
        dict_users[name] = value
        check(dict_users)

def check(name):
    if name in dict_users.items():
        password = input('{name}'.format(**dict_users) + "s"+ " Password: "))
        #add password input to existing dictionary key
        dict_users[name] = password

#Dictionary of Users
dict_users = {}

No need to use string formatting here.

Also, see how you have to test if a key exists in a dict

def check(name):
    if name in dict_users:
        password = input(name + "'s"+ " password: "))
        #add password input to existing dictionary key
        dict_users[name] = password
