如何爲我的密碼創建一個while循環

Question

def SignupDetails(): 

    Name= input("enter name: ") 
    Age= int(input("enter your age: ")) 
    yeargroup= input("Enter your year group: ") 
    username= Name[0:3]+str(Age) 
    print("username: ",username) 
    Password= input("please enter a password: ") 
    Password2= input("re-enter your password to confirm: ") 
    if Password != Password2: 
    print("the passwords do not match") 

我想創建一個while循環，這將使用戶在密碼和密碼2匹配前一直輸入密碼。任何幫助將不勝感激

Answer 1

試試這個：

Password= input("please enter a password: ") 
Password2= input("re-enter your password to confirm: ") 

while Password != Password2: 
    print("the passwords do not match") 
    Password2= input("re-enter your password to confirm: ")

可以擴展，以使用戶重新輸入第一密碼爲好，像這樣的東西：

Password= input("please enter a password: ") 
Password2= input("re-enter your password to confirm: ") 

while Password != Password2: 
    Password2 = input("The passwords do not match, hit enter to start again or re-enter your previous password to confirm: ") 
    if Password2 == "": 
     Password= input("please enter a password: ") 
     Password2= input("re-enter your password to confirm: ")
