有些害羞。。。学生查询v3.0
经过一段时间的气质（弃置）后，我把Python捡了回来第一个练手的目标就是学生查询
我在电脑上搜了有一段时间才把他找到
本次更改内容：美化界面
上源码：from time import sleep
from random import randint
def print_all():
print("现在打印所有学生的档案：")
sleep(1)
if not (data == []):
for student in data:
print("学生ID: %s" % student["ID"], end = " ")
sleep(1)
print("姓名：%s" % student["name"], end=" ")
sleep(1)
print("性别：%s" % student["sex"], end=" ")
sleep(1)
print("地址：%s" % student["address"], end=" ")
sleep(1)
print()
else:
print('一团干草默默飘过。。。')
def someThing_put_in():
ID = randint(100000000, 999999999)
try:
if ID in data:
ID = randint(100000000, 999999999)
except:
print("调试错误！")
someName = input("输入姓名：")

student = {"ID": ID, "name": someName, "sex": someSex, "address": someAddress}
data.append(student)

print("为了确保您是管理员，请输入学生全名（非小名）")
somename = input()
try:
for i in data:
if i["name"] == somename:
print(i)
except:
print("有错误")
def write_student():
someBody = input("请输入学生全名（非小名）:")

可以考虑搞个 tkinter 啥的吧，更帅气{:10_256:} Daniel_Zhang 发表于 2021-2-22 18:42

对了，能不能教我一下tkinter，我买了本书抄源代码抄到第3个就莫名其妙的出错，咋改都不行 靳子轩 发表于 2021-2-25 16:15

额...这个怎么教
如果有代码问题的话，可以新开一个帖子，等有缘人帮忙解答
我当时跟着小甲鱼学的 tkinter，但是确实有一些还是没那么容易理解的
后面去b站找了另一位大佬的教程
Tkinter 做简单的窗口视窗 (GUI 莫烦 Python 教程)
思路就清晰了挺多的
