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? Answers for all these questions are in the latest deep dive article on Playful Python - https://lnkd.in/gJkFvA24

🟢 🔰 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.

Thought about the below this morning, didn’t write it down, and I nearly lost the idea. As much as i like Python, i have realized that the significant whitespace is actually worse than curly brackets to indicate blocks. The reason is that the curly brackets are just two syntatic elements. But each line indentation is a syntactic element. Any function bigger than two lines gets hindered in comprehension by the additional syntax.

Simplify Python Dictionary Merging! Why choose | over ** or .update()? When merging dictionaries, the | operator (introduced in Python 3.9) is usually the best approach. Here's why: ➟ Concise & Readable: ▸ Forget about clunky syntax. ▸ merged = dict1 | dict2 is clean and intuitive. ➟ Non-Destructive: ▸ Unlike .update(), which modifies the first dictionary, | creates a new dictionary,  leaving your original data untouched. ➟ No Workarounds: ▸ ** unpacking works but adds verbosity. What's your go-to method for  merging dictionaries in Python?

**Sort() method in Python** ➡️ It is a built-in method in Python which is used to sort a list in either ascending or descending order ➡️Syntax: list.sort() ➡️By default, it sorts in ascending order. In order to sort in descending order, we need to pass the argument into the method **reverse=True** list.sort(reverse=True) ➡️Best Case Time Complexity: O(n) when the given list is already sorted ➡️Worst Case: O(n log n) Do like, repost and please follow Aditya Bikram Arandhara for more such content.
