Python has two ways of passing arguments to a function: positional arguments (which every language has) and keyword arguments (somewhat rarer). Have you ever thought about when you would want to use one or the other? Before you think that it probably doesn't matter, consider that python has ways for the function designer to restrict how arguments are passed - just try running len(obj=123) and see what result you get. So, does it really matter which way I pass the arguments? Why would the language have features to restrict which kind of argument should be passed?

🌟 Level 1: The Adventure Begins with Variables! 🎒🐍 🔑 What is a Variable? Imagine you have a bag in which you can store different items like numbers, words, or even more complex things. In Python, this bag is called a variable. Think of it as a way to carry and store important information for your adventure! For example, let’s say you collect gold coins during your journey. In Python, you would store that treasure like this: gold_coins = 100 Here, the gold_coins(bag) holds the value 100. You can open it anytime and see what’s inside by using Python’s magic spell: print(). print(gold_coins) # This will show the value inside your bag: 100 🧑💻 Backend Insight: When you assign gold_coins = 100, Python stores the value 100 in memory under the name gold_coins. Every time you call for it, Python knows exactly where to find that treasure!

Woof, that was tough! Although I had experience with Python, this time, I had to travel a lot further into Python by experimenting with different libraries, like PySimpleGUI, Streamlit, Pandas, FPDF, Selectorlib, PyQt6, Django, SQLAlchemy, NLTK, and image processing. It took way more to complete all the exercises, understand, and document for better remembering. Moving forward! https://lnkd.in/dK6YBnZR

🟢 🔰 Problem 147/200: 3Sum in Python ◼️ Welcome to Problem 147 of my FREE Python Problem-Solving Series! Problem: Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0. 🟩 STEPS TO SOLVE: Sort the Array: Sorting helps to easily skip duplicates and use the two-pointer technique. Find Triplets: Iterate through the array and use two pointers to find pairs that sum up to the target.

To get the current date and time in Python in the format YYYY-MM-DD H:M:S, use the datetime.now() function and import the datetime library. You can also generate integer type date as well as the string character type like 'Sun Feb DD H:M:S YYYY' using time.ctime(). Let's find out with the examples given below.
