Python3实现的简单工资管理系统示例

本文实例讲述了Python3实现的简单工资管理系统。分享给大家供大家参考，具体如下：

工资管理系统要求：

1. 查询员工工资
2. 修改员工工资
3. 增加新员工记录
4. 退出

执行代码：

#!/usr/bin/env python3

# --*-- coding: utf-8 --*--
def file_test():
  with open("info.txt",'r',encoding="utf-8") as f:
    file = list(f)
    return file
def server():
  for i in range(1):
    print("1.查询员工工资n2.修改员工工资n3.增加新员工记录n4.退出")
    return i
loginSucces = False
while True:
    i = server()
    serial_number = input("请选择你的服务>>:")
    if serial_number.isdigit():
      serial_number = int(serial_number)
      file = file_test()
      if serial_number < 5 and serial_number >= 0:
 if serial_number == 1:
   name = input("请输入要查询的员工姓名:").strip()
   for i in file:
     file = i.strip().split()
     if name in file:
break
   for i in file:
     if name in file:
name_sum = file[1]
print("33[32;1m%s的工资是：%s33[0mn"%(name,name_sum))
break
   else:
     print("33[31;1m没有此用户！33[0mn")
 elif serial_number == 2:
   name_old = input("请输入要修改的员工姓:").strip()
   for ii in file:
     file = ii.strip().split()
     if name_old in file:
print(file)
sum_old = file[1]
name_alter,sum_alter = input("请输入修改的新员工姓名和工资，用空格分割:").strip().split()
with open("info.txt","r",encoding="utf-8") as f:
  lines = f.readlines()
with open("info.txt","w",encoding="utf-8") as f_a:
  for line in lines:
    if name_old in line:
      line = line.replace(name_old,name_alter)
    f_a.write(line)
  f_a.close()
  with open("info.txt", "r", encoding="utf-8") as f:
    lines = f.readlines()
  with open("info.txt", "w", encoding="utf-8") as f_b:
    for line in lines:
      if name_alter in line:
 line = line.replace(sum_old,sum_alter)
      f_b.write(line)
    f_b.close()
    print("修改成功")
    break
    if loginSucces == True: break
   else:
     print("33[31;1m没有此用户！33[0mn")
 elif serial_number == 3:
   try:
     name_new, sum_new = input("请输入要增加的员工姓名和工资，用空格分割:").strip().split()
   except ValueError:
     print("33[31;1m输入的参数不够！33[0mn")
   else:
     if name_new.isalpha() and sum_new.isdigit():
for ii in file:
  file = ii.strip().split()
  if name_new not in file:
    with open("info.txt", "a+", encoding="utf-8") as f_c:
      f_c.write("n%s %s"%(name_new,sum_new))
    print("增加成功")
    break
    if loginSucces == True: break
     else:
print("33[31;1m参数类型不对！33[0mn")
 elif serial_number == 4:
   print("33[31;1m谢谢使用，下次再见！33[0mn")
   exit()
      else:
 print("33[31;1m请输入正确的序号！33[0mn")
    else:
      print("33[31;1m输入的不是整数！33[0mn")
