python3学生名片管理v2.0版

python学生名片管理vv2.0是在1.0的基础上增加部分功能,实现将数据存入文件保存,以便于程序停止后还能再次取到数据。具体实现请看如下部分:

card_main.py

import sys

from One.card_func2 import *

def head():

print('*' * 30)

print('学生信息管理系统v2.0')

print('1.添加学生\t2.显示所有\t3.查询学生\t0.退出系统')

print('*' * 30)

def main():

while True:

head()

num = input('输入操作:')

if num == '1':

print('选择功能添加学生')

add_card()

elif num == '2':

print('选择功能添显示所有')

show_all()

elif num == '3':

print('选择功能查询学生')

search_card()

elif num == '0':

sys.exit()

else:

print('输入有误,命令无效')

if __name__ == '__main__':

main()

card_func2.py

import json

import time

stutent_list = []

def add_card():

name = input('请输入姓名:')

age = input('请输入年龄:')

qq = input('请输入QQ:')

mail = input('请输入邮箱:')

dict = {}

dict['name'] = name

dict['age'] = age

dict['qq'] = qq

dict['mail'] = mail

stutent_list.append(dict)

memory(stutent_list)

def memory(stutent_list): # 将数据存入文件

with open('student.json', 'w') as f:

for i in stutent_list:

json_i = json.dumps(i)

f.write(json_i+'\n')

f.close()

def repick(): # 从文件中去除数据

risk_result = []

with open('student.json', 'r') as f:

risk_new_list = f.read().split('\n')[:-1]

for x in risk_new_list:

json_x = json.loads(x)

risk_result.append(json_x)

f.close()

return risk_result

def show_all():

global stutent_list

stutent_list = repick()

table_head()

for dict in stutent_list:

print('-' * 32)

print('| %s\t|\t%s\t|\t%s\t|\t%s\t|' % (dict['name'], dict['age'], dict['qq'], dict['mail']))

def search_card():

global stutent_list

for dict in stutent_list:

if dict['name'] == name:

table_head()

print('-' * 32)

print('| %s\t|\t%s\t|\t%s\t|\t%s\t|' % (dict['name'], dict['age'], dict['qq'], dict['mail']))

print('您可以执行操作:1.删除\t2.修改\t3.返回上一级')

deal_card(dict)

break

else:

print('查无此人!!!')

def table_head():

print('_' * 32)

print('| 姓名\t|\t年龄\t|\tQQ\t|\t邮箱\t|')

def deal_card(dict):

order = input('请输入命令:')

while True:

if order == '1':

delete_card(dict)

break

elif order == '2':

modify_card(dict)

break

elif order == '3':

break

else:

print('输入有误,命令无效')

def delete_card(dict):

print('执行命令,删除数据')

stutent_list.remove(dict)

print('...正在删除,请等待...')

turnTime()

print('删除成功,返回主界面')

def modify_card(dict):

print('执行命令,修改数据')

dict['name'] = input('请输入姓名:')

dict['age'] = input('请输入年龄:')

dict['qq'] = input('请输入QQ:')

dict['mail'] = input('请输入邮箱:')

print('...正在修改,请等待...')

turnTime()

print('修改成功,返回主界面')

def turnTime():

for i in list(range(5, 0, -1)):

print(i, 's')

time.sleep(1)
