10 个顺手级的 Python 自动化脚本

以下是 10 个实用的 Python 自动化脚本，适合各种需求。

图片优化器
使用 Pillow 模块来编辑图像。

# Image Optimizing
# pip install Pillow
import PIL

# Croping
im = PIL.Image.open("Image1.jpg")
im = im.crop((34, 23, 100, 100))

# Resizing
im = PIL.Image.open("Image1.jpg")
im = im.resize((50, 50))

# Flipping
im = PIL.Image.open("Image1.jpg")
im = im.transpose(PIL.Image.FLIP_LEFT_RIGHT)

# Rotating
im = PIL.Image.open("Image1.jpg")
im = im.rotate(360)

# Compressing
im = PIL.Image.open("Image1.jpg")
im.save("Image1.jpg", optimize=True, quality=90)

# Bluring
im = PIL.Image.open("Image1.jpg")
im = im.filter(PIL.ImageFilter.BLUR)

# Sharpening
im = PIL.Image.open("Image1.jpg")
im = im.filter(PIL.ImageFilter.SHARPEN)

# Set Brightness
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageEnhance.Brightness(im)
im = im.enhance(1.5)

# Set Contrast
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageEnhance.Contrast(im)
im = im.enhance(1.5)

# Adding Filters
im = PIL.Image.open("Image1.jpg")
im = PIL.ImageOps.grayscale(im)
im = PIL.ImageOps.invert(im)
im = PIL.ImageOps.posterize(im, 4)

# Saving
im.save("Image1.jpg")

视频优化器
使用 MoviePy 模块来优化视频。

python
# Video Optimizer
# pip install moviepy
import moviepy.editor as pyedit

# Load the Video
video = pyedit.VideoFileClip("vid.mp4")

# Trimming
vid1 = video.subclip(0, 10)
vid2 = video.subclip(20, 40)
final_vid = pyedit.concatenate_videoclips([vid1, vid2])

# Speed up the video
final_vid = final_vid.speedx(2)

# Adding Audio to the video
aud = pyedit.AudioFileClip("bg.mp3")
final_vid = final_vid.set_audio(aud)

# Reverse the Video
final_vid = final_vid.fx(pyedit.vfx.time_mirror)

# Merge two videos
vid1 = pyedit.VideoFileClip("vid1.mp4")
vid2 = pyedit.VideoFileClip("vid2.mp4")
final_vid = pyedit.concatenate_videoclips([vid1, vid2])

# Add VFX to Video
vid1 = final_vid.fx(pyedit.vfx.mirror_x)
vid2 = final_vid.fx(pyedit.vfx.invert_colors)
final_vid = pyedit.concatenate_videoclips([vid1, vid2])

# Add Images to Video
img1 = pyedit.ImageClip("img1.jpg")
img2 = pyedit.ImageClip("img2.jpg")
final_vid = pyedit.concatenate_videoclips([img1, img2])

# Save the video
final_vid.write_videofile("final.mp4")

PDF 转图片
将 PDF 页面转换为图像。

# PDF to Images
# pip install PyMuPDF
import fitz

def pdf_to_images(pdf_file):
    doc = fitz.open(pdf_file)
    for p in doc:
        pix = p.get_pixmap()
        output = f"page{p.number}.png"
        pix.writePNG(output)

pdf_to_images("test.pdf")

获取 API 数据
从 API 获取或发布数据。

# pip install urllib3
import urllib3

# Fetch API data

http = urllib3.PoolManager()
response = http.request('GET', url)
print(response.status)
print(response.data)

# Post API data
url = "https://httpbin.org/post"
http = urllib3.PoolManager()
response = http.request('POST', url, fields={'hello': 'world'})
print(response.status)

电池指示灯

# Battery Notifier
# pip install plyer
from plyer import notification
import psutil
from time import sleep

while True:
    battery = psutil.sensors_battery()
