想了解Python函数实现学员管理系统的相关内容吗,bluenessdrops在本文为您仔细讲解Python学员管理系统的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:python学员管理系统,python管理系统,python学员管理,下面大家一起来学习吧。

这个是一个简单的管理程序

输入姓名,年龄,性别(也可以添加其他类别例如性取向),然后以列表的形式保存(默认为空列表)。功能如下:

大概就是这样子。下面是代码:

import time

def main():
  '''主函數'''
  while True:
    sl(),select_function()
    sl()
    user_input = input('select your operation: ')
    if   user_input == '1':
      sl(),add_op()
    elif user_input == '2':
      sl(),delete_op()
    elif user_input == '3':
      sl(),alter_op()
    elif user_input == '4':
      sl(),search_op()
    elif user_input == '5':
      sl(),print_op()
    elif user_input == '6':
      print('\n system quit.')
      break
    else:
      sl(),print('\n plz enter correct number.')


def select_function():
  '''顯示系統功能'''
  print("\n1.add mbr\n2.delete mbr\n3.change info\
         \n4.check info\n5.prt\'l info\n6.exit sys\n")
  sl()
def store_new_info():
  a = input('enter name: ').title()
  b = input('enter age: ').title()
  c = input('enter gender: ').title()
  return a,b,c

def add_op():
  '''添加新人'''
  name,age,gender = store_new_info()
  for i in all_info:
    if name == i['name'].strip():
      print(f'{name} is existed.retry plz')
      break
  else:
    dict_inf = {}
    dict_inf['name']   = name
    dict_inf['age']    = age
    dict_inf['gender'] = gender
    all_info.append(dict_inf)
    print(f'{name} added.')

def delete_op():
  '''刪除已有人物'''
  del_nam = input('type the name to del:').title()
  for i in all_info:
    if del_nam == i['name'].strip():
      all_info.remove(i)
      sl(),print(f'{del_nam} is removed.')
  else:
    sl(),print(f'no {del_nam} in list now.')

def alter_op():
  '''修改現有人物信息'''
  alter_nam = input('type the name who needs change: ').title()
  for i in all_info:
    if alter_nam != i['name'].strip():
      continue
    else:
      i['age'] = input('type new age: ')
      i['gender'] = input('type new gender: ')
      break
  else:
    sl(),print(f'no {alter_nam} in list.')

def search_op():
  '''查找某個人物的信息'''
  se_num = input('type name to search: ').strip().title()
  for i in all_info:
    if se_num != i['name'].strip():
      continue
    else:
      sl(),print(i)
      break

def modify_op():
  '''統一name首字母大寫且左對齊'''
  b = 0
  for i in range(len(all_info)): 
    a = len(all_info[i].get('name').strip())
    b = max(a,b)
  for i in range(len(all_info)):
    all_info[i]['name']   = all_info[i].get('name').strip().title().ljust(b,' ')
    all_info[i]['gender'] = all_info[i].get('gender').strip().title().ljust(6,' ')

def print_op():
  '''輸出所有人物的全部信息'''
  modify_op()
  for i in all_info:
    print('\n',i,'\n')

def sl():
    time.sleep(0.5)

all_info = []
main()
