🐍 Part 2: 5 More Python Scripts That Will Save You Hours Every Week!!

#python #productivity #automation #programming

Back with 5 more small-but-mighty Python scripts to automate your everyday tasks and boost your productivity!!

📧 1. Email Yourself a Daily Journal Entry
Save thoughts, goals, or reflections — delivered straight to your inbox.

import smtplib
from email.mime.text import MIMEText

body = input("What's on your mind today?\n")
msg = MIMEText(body)
msg['Subject'] = '📝 Daily Journal'
msg['From'] = 'you@example.com'
msg['To'] = 'you@example.com'

server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login('you@example.com', 'your_app_password')
server.send_message(msg)
server.quit()
Enter fullscreen mode Exit fullscreen mode

✔️ Use an App Password if using Gmail.

🗂️ 2. Convert CSV to JSON in Seconds.
Perfect for web devs, APIs, or when switching formats.

import csv
import json

with open('data.csv', 'r') as f:
    reader = csv.DictReader(f)
    rows = list(reader)

with open('data.json', 'w') as f:
    json.dump(rows, f, indent=4)
Enter fullscreen mode Exit fullscreen mode

✔️ Swap CSV → JSON or vice versa with a quick tweak.

🔍 3. Find and Replace Text in Multiple Files
Update project files, configs, or logs in bulk.

import os

folder = 'my_project'
for file in os.listdir(folder):
    if file.endswith('.txt'):
        path = os.path.join(folder, file)
        with open(path, 'r+') as f:
            content = f.read().replace("OLD_TEXT", "NEW_TEXT")
            f.seek(0)
            f.write(content)
            f.truncate()
Enter fullscreen mode Exit fullscreen mode

✔️ Automate tedious refactoring or content cleanup.

🎵 4. Download YouTube Videos as MP3 (Audio Only).
Use this responsibly and for personal content.

from pytube import YouTube

url = input("YouTube URL: ")
yt = YouTube(url)
stream = yt.streams.filter(only_audio=True).first()
stream.download(filename="audio.mp3")
Enter fullscreen mode Exit fullscreen mode

✔️ Turn lectures, podcasts, or tutorials into offline audio.

🌐 5. Check If Your Internet Is Working (and Speed)

import speedtest

st = speedtest.Speedtest()
print(f"Download: {st.download() / 1_000_000:.2f} Mbps")
print(f"Upload: {st.upload() / 1_000_000:.2f} Mbps")
Enter fullscreen mode Exit fullscreen mode

✔️ Use in automation or when debugging slow web apps.

I always thought Python was mostly for big projects, but seeing these quick scripts really made me realize how much it can help with everyday tasks. The CSV to JSON and internet speed tester were especially eye-opening for me!
