Enter the account password to complete the verification, verification after the output, "Login Successful"

dic={"name":'admin', "password":'123'}
name = input(">>>user:")
password = input(">>>password:")
if name in dic["name"] and password in dic["password"]:
    print("登录成功")
else:
    print("登录成功")

Different users can log

dics = {
    "admin": {"password": '123'},
    "egon": {"password": '123'}
}
name = input(">>>user:")
password = input(">>>password:")
if name in dics and password == dics[name]["password"]:
    print("登录成功")
else:
    print("登录失败")

Unsuccessful attempts to enter the same account lock (additional functions in the case of the program has been running, once locked, the lock automatically unlock after 5 minutes)

import time
dics = {
    "admin": {"password": '123'},
    "egon": {"password": '123'}
}
count = 0
while True:
    name = input(">>>user:")
    password = input(">>>password:")
    if count < 3 and name in dics and password == dics[name]["password"]:
        print("登录成功")
        break
    else:
        print("登录失败")
        if count < 3:
            count += 1
            continue
        else:
            print("该账号已被锁定，五分钟后重试")
            time.sleep(300)
            count = 0
            continue

Expansion needs: Based on the 3 completed once the user is locked, regardless of whether the program is closed, all locked 5 minutes

import time, os
dics = {
    "admin": '123',
    "egon": '123'
}
count = 1
while True:
    if os.path.exists('lock.txt'):
        with open('lock.txt', 'r', encoding='utf-8') as f:
            ti = f.read()
        if ti == '300':
            print("已被锁定无法输入,五分钟后解锁")
            time.sleep(int(ti))
            with open('lock.txt', 'w', encoding='utf-8') as f:
                f.write("0")
            print("解锁成功！请输入")
    name = input(">>>user:")
    password = input(">>>password:")
    if name in dics:
        if count < 3 and password == dics.get(name):
            print("登录成功")
            break
        else:
            print("密码错误，登录失败")
            if count < 3:
                count += 1
            else:
                with open('lock.txt', 'w', encoding='utf-8') as f:
                    f.write("300")
                print("已被锁定五分钟")
    else:
        print("账号不存在")
