python小项目--信息管理系统---新手实践
一，功能简介
除最基本的增，删，改，查，多加了一个导出为excel表格的功能。比较适合刚学完python练习基本语言用。代码中大部分都是使用基本语法来处理数据。
新建和查看
搜索时，界面确实不怎么美观，家庭住址这一栏也直接到了下一行，时间原因，也懒得修改了。
修改：
先选择要修改的信息
改动：
信息覆盖：
删除和修改的界面几乎一样一个多选的对话框，这里不展示了。
导出表格：其中C:/Users/acer/Desktop/信息.xlsx为默认路径，选择导出功能时会自动填入
二，代码
个人小白，python学的比较浅，GUI也是用的自带模块easygui
运行时会生成名为employee_date.json的文件来存储信息
main.py：
import easygui
import function as fun
while True:
main_menu = easygui.buttonbox('\t\t\t\t菜单界面', title='信息管理系统',
choices=['新建信息', '查看所有信息',
'搜索信息', '修改信息', '删除信息',
'导出为excel表格'])
if main_menu == '新建信息':
try:
fun.new_employee()
except FileNotFoundError:
fun.new_filename()
elif main_menu == '查看所有信息':
try:
fun.data_all()
except FileNotFoundError:
fun.tip_not_found_file()
elif main_menu == '修改信息':
try:
fun.modify_employee()
except FileNotFoundError:
fun.tip_not_found_file()
elif main_menu == '删除信息':
try:
fun.del_data()
except ValueError:
fun.del_data2()
except FileNotFoundError:
fun.tip_not_found_file()
elif main_menu == '搜索信息':
try:
fun.search_data()
except FileNotFoundError:
fun.tip_not_found_file()
elif main_menu == '导出为excel表格':
try:
fun.export_to_excel()
except FileNotFoundError:
fun.tip_not_found_file()
elif main_menu == None:
break

三，一些废话
总共不到300行，python的确是一门简洁的语言，用c的话估计冲着五六百行就去了，python作为辅助语言不错，但不建议作为第一语言来使用。隐去了很多我们不需要考虑的内容。
