What are some practical Python scripts?

System Prompt Tool

This tool uses the win10toast library to trigger system notifications and can be used to prompt important things.

#定时通知脚本
from win10toast import ToastNotifier
import time
#构建通知对象实例
toaster = ToastNotifier()

title = input("请输入事件标题:")
content = input("请输入事件提要")
time_min = float(input("请输入提醒时间(分钟):"))

#time_min = time_min * 60
print("设置完成！")
time.sleep(1)
print("开始运行..")
time.sleep(time_min)
toaster.show_toast(f"{title}", f"{content}", duration=10, threaded=True)
while toaster.notification_active(): time.sleep(0.005)

Convert PDF files to audio

import pyttsx3
import pyPDF2

book = open('路径/book.pdf',rb)
pdfreader = pyPDF2.PdfFileReader(book)
pages = pdfreader.numPages
print(pages)

voice = pyttsx3.init()
page = pdfreader.getpage(3)
text = page.extractText()
speaker.say(text)
speaker.runAndWait()

Batch compressed files

import zipfile # zipfile库 压缩文件
import os
import time


def batch_zip(start_dir):
    start_dir = start_dir #文件路径
    file_news = start_dir + '.zip' # 压缩后文件夹的名字

    z = zipfile.ZipFile(file_news, 'w', zipfile.ZIP_DEFLATED)
    for dir_path, dir_names, file_names in os.walk(start_dir):
        #避免从根目录复制
        f_path = dir_path.replace(start_dir, '')
        #压缩所有文件
        f_path = f_path and f_path + os.sep
        for filename in file_names:
            z.write(os.path.join(dir_path, filename), f_path + filename)
     z.close()
     return file_news


batch_zip('./data/ziptest')

Send by email

# 1、导入模块
import yagmail

# 2、设置smtp服务信息
yag = yagmail.SMTP(user="改成自己的邮箱账号@126.com", password="改成自己的邮箱密码", host='smtp.126.com')

# 3、设置邮件主题与邮件内容
subject = 'Python邮件测试'
content = ['Python邮件测试 -- 邮件来自黑马程序员Python+大数据']

# 4、发送邮件
yag.send('gocndws@126.com', subject, content)
