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")

03. Convert PDF to Image

This small automated script can easily retrieve entire PDF pages and convert them to images. This script uses the popular PyMuPDF module, known for its PDF text extraction.

# 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")

04. Get API data

If you need to get API data from the database, or need to send API requests to the server, this automation script is a convenient tool for you. Using the Urlib3 module, you can get and make API requests.

# pip install urllib3
输入urllib3
# 获取API数据
url = "https://api.github.com/users/psf/repos"
http = urllib3.PoolManager()
response = http.request('GET', url)
print(response.status)
print(response.data)
# 发布API数据
url = "https://httpbin.org/post"
http = urllib3.PoolManager()
response = http.request('POST', url, fields={'hello': 'world'})
print(response.status)

05, Battery Indicator

This handy script allows you to set the battery percentage at which you want to receive notifications. The script uses Pyler for notifications and Psutil to get the current battery percentage.

# 电池通知器
# pip instal plyer
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",
            timeout = 10
        )
    sleep(60)

06, Grammar Corrector

Tired of proofreading your long articles or texts? Well, you can try this automatic script that will scan your text and correct grammatical errors. This great script uses the Happtransformer module, which is a machine learning module trained to correct grammatical errors in text.

# Grammer Fixer

from happytransformer import HappyTextToText as HappyTTT
from happytransformer import TTSettings
def Grammer_Fixer(Text):
    Grammer = HappyTTT("T5","prithivida/grammar_error_correcter_v1")
    config = TTSettings(do_sample=True, top_k=10, max_length=100)
    corrected = Grammer.generate_text(Text, args=config)
    print("Corrected Text: ", corrected.text)
Text = "This is smple tet we how know this"
Grammer_Fixer(Text)
