Python's Power: Mastering Everyday Coding Tasks

🚀 Unlocking Python's Power: Mastering Everyday Coding Tasks!

🔍 Let's dive into the realm of Python one-liners, where a single line of code packs a powerful punch! 💥 Here are some nifty tricks to streamline your coding tasks:

• Read Lines from a File: 📄 Accessing file content effortlessly!

lines = [line.strip() for line in open('example.txt')]

• Count Lines in a File: 📏 Keeping track of file length like a pro!

line_count = sum(1 for line in open('example.txt'))

• List Comprehension with Conditional: 🌟 Filtering lists with ease!

filtered_list = [x for x in my_list if x > 0]

• Calculate Average of a List: 📊 Math made simple!

average = sum(my_list) / len(my_list) if len(my_list) > 0 else 0

• Conditional Value Assignment: 🎯 Let Python make decisions for you!

result = x if condition else y

• Handle Zero Division Error: ⚠️ Avoiding pitfalls gracefully!

result = numerator / denominator if denominator != 0 else 0

• Fetch HTML Content with Requests: 🌐 Bringing web data to your fingertips!

import requests; html_content = requests.get('https://example.com').text

• Multithreading with threading Module: 🚀 Boosting performance with parallelism!

import threading; threading.Thread(target=my_function).start()

• Hashing with hashlib: 🔒 Keeping passwords secure with hashing!

import hashlib; hashed_password = hashlib.sha256(password.encode()).hexdigest()

• Check if a key exists in a dictionary: 🗝️ Navigating dictionaries like a seasoned explorer!

is_present = 'key' in {'key': 'value'}

• Removing duplicates from a list while preserving order: 🔄 Keeping things tidy without losing track!

unique_list = list(dict.fromkeys([1, 2, 2, 3, 4]))

• Download a file from a URL: 📥 Fetching files with finesse!

urllib.request.urlretrieve("https://lnkd.in/gsGhU6f7", "downloaded_file.zip")

• List files in a directory: 📂 Exploring directories with Python's directory prowess!

files = [f for f in os.listdir("path/to/dir") if os.path.isfile(os.path.join("path/to/dir", f))]
