查课表，以前用的是超级课程表，嫌乎广告太多，加上手机内存不够，卸了，自己写个课表。
由于学校教务系统的参数太多了，直接用了selenium来模拟登录，之后再用BeautifulSoup来分离参数。
流程：查看本地json格式的课表文件，若没有则爬并存储，若有则直接读取并输出。
做的时候发现单双周挺难弄的，最后是用了空间换时间的方法，把一个单双周合起来变成一个课表。
最后用Power Automate 简单做了一个桌面流：
结果：
附源代码：
from selenium import webdriver # 启动浏览器需要用到
from selenium.webdriver.common.keys import Keys # 提供键盘按键支持（最后一个K要大写）
from bs4 import BeautifulSoup
import time
import re
import json
#输入账号密码
student_id=""
studend_password=""
#输入浏览器内核位置，如F:\\chromedriver_win32\\chromedriver.exe
place="F:\\chromedriver_win32\\chromedriver.exe"
#输入开学日期，格式：30 Aug 2021
time_to_strat = "30 Aug 2021"
#爬取后课表的存储位置
stored_place = "F:\\ProbeN1\\timetable\\"
#判断明天是周几,是不是单双周
start_time = time.strptime(time_to_strat, "%d %b %Y")
start_week = time.strftime("%U", start_time)
tomorrow_time_tamp = time.time()+86400
tomorrow_time = time.localtime(tomorrow_time_tamp)
tomorrow_week = time.strftime("%U", tomorrow_time)
weekin = int(tomorrow_week) - int(start_week) + 1
#print(weekin) #单双周
dt = time.strftime("%A",tomorrow_time)
dt_ = {"Saturday":"6","Sunday":"0","Monday":"1","Tuesday":"2","Wednesday":"3","Thursday":"4","Friday":"5"}
tomorrow_weekday = dt_[dt]
#print(tomorrow_weekday) #周几
time_judge=[weekin,tomorrow_weekday]
def print_class(timetable,time_judge):
print(timetable["flag"]["1"])
if int(time_judge[1])==6 or int(time_judge[1])==0 :
print("明天没课!")
else :
print("---------------------------------------------------")
if (time_judge[0] % 2) == 0:
tmp = timetable["双"][str(time_judge[1])]
for each in tmp.values():
for i in range (0,4):
print(each[i])
print("---------------------------------------------------")
elif (time_judge[0] % 2) == 1:
tmp = timetable["单"][str(time_judge[1])]
for each in tmp.values():
for i in range (0,4):
print(each[i])
print("---------------------------------------------------")

#写入文件
with open(stored_place+'file.txt', 'w') as file:
timetable["flag"]["1"] = student_name
timetable["flag"]["2"] = "stored"
file.write(json.dumps(timetable))
print_class(timetable,time_judge)
#print(timetable)
当然，之后也新建一个bat帮助自动执行
f:
cd F:\ProbeN1\timetable
python3 timetable.py
pause
然后再在windows里设置
