Python3 實現用戶登陸，輸入三次密碼

不加注釋版

#/usr/bin/python3
import readline
user = "seven"
passwd = "123"
username = input("please the enter user:")
for i in range(3):password = input("please the enter password:")if password.isdigit():password = int(password)if username == user and password == passwd:print("logon successfull")breakelse:print("logon failed")else:print("logon failed")

加注釋版

#/usr/bin/python3
import readline#導入readline模塊，否則無法移動光標和刪除
user = "seven"
passwd = "123"#定義賬號密碼
username = input("please the enter user:")#提示用戶輸入賬號信息  for i in range(3):#如果登陸失敗允許重復輸入三次password = input("please the enter password")#提示用戶輸入密碼if password.isdigit():#判斷輸入的是否是數字 是則進行下一步 否則返回失敗password = int(password)#賦值定義密碼等于輸入密碼if username == user and password == passwd:#判斷賬號和密碼是否一致print("logon successfull")#Truebreakelse:print("logon failed")#Falseelse:print("logon failed")#不是數字則返回False
