本文实例为大家分享了python实现学生管理系统的具体代码，供大家参考，具体内容如下
一.面向过程版
import os
stu_list = []
def show_menu():
print(\'1.添加学生\')
print(\'2.删除学生\')
print(\'3.修改学生信息\')
print(\'4.查询单个学生信息\')
print(\'5.查询所有学生信息\')
print(\'6.退出系统\')

if stu[\'name\'] == name:
print(\'.........学生信息已存在........\')
return
age = input(\'请输入学生年龄:\')
gender = input(\'请输入学生性别:\')
stu_dict = {\'name\': name, \'age\': int(age), \'gender\': gender}
stu_list.append(stu_dict)
print(\"学生信息添加成功!\")
def remove_student():
name = input(\'请输入要操作的学生的名字:\')
for stu in stu_list:
if stu[\'name\'] == name:
stu_list.remove(stu)
print(\'删除成功!\')
break
else:
print(\'........该学生信息不存在,无法删除.........\')
def modify_student():
name = input(\'请输入要操作的学生的名字:\')

break

if len(stu_list):
for stu in stu_list:

else:
print(\"目前没有学生信息!\")
def save():
f = open(\'student.txt\', \'w\')
f.write(str(stu_list))
f.close()
def read_file():
global stu_list
if os.path.exists(\'student.tct\'):
