一些功能性小程序段

1、注册  登陆   账号   

需要先建立wb文件

def login(mz,mm):
    f = open("wb","r",encoding="utf-8")
    i = 0
    for line in f:
        li = line.strip().split("#")
        i = 0
        if mz ==li[0] and mm == li[1]:
            print("登陆成功")
            i = 1
            break
        else:
            continue
    if i == 0 :
        print("请继续输入:")
        main()
    f.close()

def zhuce():
    f1 = open("wb","a",encoding="utf-8")
    zhanghao = input("输入用户名：")
    mima = input("输入密码：")
    # "#".join（zhanghao,mima)
    li2 = zhanghao+"#"+mima
    f1.write("
"+li2)
    f1.close()
def main():
    su = input("1登陆   2注册")
    if su =="1":
        mizi = input("账号:")
        mima = input("密码:")
        login(mizi,mima)
    elif su =="2":
        zhuce()
    else:
        print("请输入正确的选项")
        main()
main()
