1. 实现需求为 注册、登录、查看昵称的功能
def userN():
username = input("请输入账号: \n")
password = input('请输入密码: \n')
return username,password
def register():
# 注册函数封装
username,password= userN()
temp = username + "|" + password
with open('D:\Test_Python\login.md','w') as file:
file.write(temp)
def login():
# 登录函数封装
username,password= userN()
with open('D:\Test_Python\login.md') as file:
user = file.read().split("|")
if username == user[0] and password == user[1]:
return '登录成功'
else:
return '登录失败，请检查账号或者密码'
def getNick(func):
# 查看个人主页
with open('D:\Test_Python\login.md') as file:
user = file.read().split("|")
if func:
print('{}您好，欢迎再次回来！'.format(user[0]))
else:
print('您为进行登录，请登录！')
def exit():
# 退出系统
import sys
print('系统已退出，欢迎下次再登录！')
sys.exit(1)
def Main():
while True:
put = int(input('请选择 1.注册 2.登录 3.退出系统'))
if put == 1:
register()
elif put == 2:
getNick(login())
elif put == 3:
exit()
else:
print('输入错误，请重新输入...')
continue
if __name__ == '__main__':
Main()
2. 列表a = [1,2,3,4,5,6,7]，将列表a的值赋给列表b，在不影响列表a的情况下，将列表b的值每间隔一个元素替换成6

import copy
a = [1,2,3,4,5,6,7]
b = a[:]
items = len(b)
for i in range(1,items):
# print(i)
if i%2==0:
# print(i)
b[i] = 6
print(a)
print(b)
[1, 2, 3, 4, 5, 6, 7]
[1, 2, 6, 4, 6, 6, 6]
3.让用户输入用户密码，成功打印欢迎信息，输错提示还剩几次机会，三次机会仍然错误退出程序
times = 3
while times>0:
user = input('请输入用户名:')
pwd = input('请输入密码:')
if user =='admin' and pwd =='admin':
print('欢迎进入KZ系统')
if times != 0:
print('您还剩'+str(times-1)+'次机会')
else:
pass
else:
if user == 'Admin' and pwd == '':
print('密码错误')
if times != 0:
print('您还剩'+str(times-1)+'次机会')
else:
pass
else:
print('输入有误')
if times != 0:
print('您还剩'+str(times-1)+'次机会')
# continue
else:
break
times -= 1
