python学习随笔day1

自学python一两个月，感觉太零散了，最初学习目的是爬虫，学着学着数据分析、opencv识别等等，结果感觉什么都没学上。

现在决定重新从基础一步步学习

学习笔记（1）简单登录

#_*_coding:utf-8*_

#登录接口
username="abc"
password="123"



count1 = 0
while True:
    if count1 ==3:
        print("while :连续猜错3次，自动退出。")
        break
    guess_username= input('username:')
    guess_password = input('password:')


    if guess_username != username:
        print("帐号错误")
    elif guess_password != str(password):
        print("密码错误")
    else:
        print("登录成功")
    count1 = count1+1
    if count1==3:
        continue_confirm = input("请确认继续guess:y/n")
        if continue_confirm != 'n':
            count1=0;

学习笔记（2）多菜单 -验证码登录

count2 = 0
while True:
    if count2 ==3:
        print("homework:连续猜错3次，自动退出。")
        break
    guess_username= input('username:')
    guess_password = input('password:')
    guess_code=input("code:")

    if guess_username != username:
        print("帐号错误")
    elif guess_password != str(password):
        print("密码错误")
    elif guess_code != code:
        print("验证码错误")
    else:
        print("登录成功")
        break
    count2 = count2+1
    if count2==3:
        continue_confirm = input("请确认继续guess:y/n")
        if continue_confirm != 'n':
            count2=0;
