10 Python Automation Scripts for Killer Applications

01, Image Optimizer

This great automation script can help you process images better, you can just like in Photoshop Edit them.

This script uses the popular Pillow module.

# 图像优化
# pip install Pillow
import PIL
# 裁剪 
im = PIL.Image.open("Image1.jpg")
im = im.crop((34, 23, 100, 100))
# 调整大小
im = PIL.Image.open("Image1.jpg")
im = im.resize((50, 50))
# 翻转
im = PIL.Image.open("Image1.jpg")
im = im.transpose(PIL.Image.FLIP_LEFT_RIGHT)
# 旋转
im = PIL.Image.open("Image1.jpg")
im = im.rotate(360)
# 压缩
im = PIL.Image.open("Image1.jpg")
im.save("Image1.jpg", optimize=True, quality=90)
# 模糊化
im = PIL.Image.open("Image1.jpg")
im = im.filter(PIL.ImageFilter.BLUR)
# 锐化
im = PIL.Image.open("Image1.jpg")
im = im.filter(PIL.ImageFilter.SHARPEN)
# 设置亮度
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageEnhance.Brightness(im)
im = im.enhance(1.5)
# 设置对比度
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageEnhance.Contrast(im)
im = im.enhance(1.5)
# 添加过滤器
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageOps.grayscale(im)
im = PIL.ImageOps.invert(im)
im = PIL.ImageOps. posterize(im, 4)
# 保存
im.save("Image1.jpg")

02, Video Optimizer

With the following automated script, you can not only use Python to optimize videos, but also use it to optimize images. This script uses the Moviepy module, which allows you to trim, add audio, set video speed, add VFX, and more.

# 视频优化器
# pip install moviepy
import moviepy.editor as pyedit
# 加载视频
video = pyedit.VideoFileClip("vid.mp4")
# 修剪
vid1 = video.subclip(0, 10)
vid2 = video.subclip(20, 40)
final_vid = pyedit.concatenate_videoclips([vid1, vid2])
# 加快视频的速度
final_vid = final_vid.speedx(2)
# 在视频中添加音频
aud = pyedit.AudioFileClip("bg.mp3")
final_vid = final_vid.set_audio(aud)
# 反转视频
final_vid = final_vid.fx(pyedit.vfx.time_mirror)
# 合并两个视频
vid1 = pyedit.VideoFileClip("vid1.mp4")
vid2 = pyedit.VideoFileClip("vid2.mp4")
final_vid = pyedit.concatenate_videoclips([vid1, vid2])
# 在视频中添加视觉特效
vid1 = final_vid.fx(pyedit.vfx.mirror_x)
vid2 = final_vid.fx(pyedit.vfx.invert_colors)
final_vid = pyedit.concatenate_videoclips([vid1, vid2])
# 在视频中添加图像
img1 = pyedit.ImageClip("img1.jpg")
img2 = pyedit.ImageClip("img2.jpg")
final_vid = pyedit.concatenate_videoclips([img1, img2])
# 保存视频
final_vid.write_videofile("final.mp4")

from plyer import notification
import psutil
from time import sleep
while True:
   battery = psutil.sensors_battery()
    life = battery.percent
    #寿命 = 电池百分比
    if life < 50:
        notification.notify(
            title = "Battery Low" #电池电量不足
            message = "Please connect to power source",
