Python int type has no limit, unlike T-SQL

Problem: Contains Duplicate (LeetCode #217) 💡 Concept Learned: Today I practiced a simple LeetCode problem: Contains Duplicate using Python. At first, I tried the brute-force approach by comparing each element with every other element using nested loops. It works, but it’s slow when the list becomes large. Then I learned a better way using a set. A key insight: If an element is already present in the set while traversing the array, a duplicate exists. 🎯 Key Takeaway: Choosing the right data structure makes a huge difference. A Hash Set helps reduce the time complexity from O(n²) to O(n) by enabling constant-time lookups. 📈 Slowly building confidence by solving one problem at a time and learning from mistakes. #DSA #LeetCode #100DaysOfCode #HashTable #Set #ProblemSolving #Python #CodingJourney #LearningInPublic #CodeNewbie

💡 A small Python lesson from LeetCode While solving LeetCode #8 (String to Integer – atoi), I wrote two solutions that were both O(n) and logically identical. But one was faster. The reason? Not the algorithm but the way the code was written. Using elif instead of multiple if checks and avoiding extra branching made a noticeable difference. In Python, fewer condition checks = fewer instructions = better runtime. Nice reminder that Big-O isn’t everything, especially in interpreted languages. Learning moments like these are why I enjoy solving problems 😄 #Python #LeetCode #LearningInPublic #SoftwareEngineering #ProblemSolving

Consistency beats complexity 🔁 I recently built a calculator in Python using for loop and range(). Implemented a calculator in Python using for loop and range(), and it felt great to turn theory into something functional. Projects like these strengthen problem-solving skills and build confidence step by step. Looking forward to exploring more Python concepts! 🚀 Learning one concept at a time—and enjoying the process! 💻✨ #PythonJourney🔥

Day 44 – Python with DSA 🐍📘 Today I learned one of the most important DSA techniques: Sliding Window. 🔹 What I understood: Used for subarray Helps optimize solutions from O(n²) to O(n) Works by adding one element and removing one element instead of recalculating 🔹 Problems practiced: Maximum Average Subarray Minimum Size Subarray Sum This concept really helped me understand how to think efficiently while solving problems. Slow progress is still progress 🚀 Consistency > Speed 💪 #Day44 #Python #DSA #SlidingWindow #LeetCode #SDE#CodingJourney

I spent 2 hours on a loop. Python dictionaries can do it in one line. I was processing a list of data. I needed to group items by a key. I used a loop. It worked. But it was slow. Python dictionaries have a trick. Use a dictionary comprehension. It's fast and clean. 🚀 💡 Key Takeaway: Use dictionary comprehensions. They are fast and easy. 🐍 Have you used this trick?

🚀Day 12 -Ord() and chr() in python In Python, the ord() and chr() functions are used to convert characters to their Unicode values and vice versa. The ord() function returns the Unicode (ASCII) value of a character. The chr() function returns the character from a Unicode value. #Python #LearnPython #PythonProgramming #CodingBasics #DataScience #ProgrammingJourney

LIFE LESSONS FROM CODE 5 Python once raised an error that said: NameError: name 'x' is not defined 😅 I was confident. I knew what I meant. But Python didn’t care about my assumptions. I tried to use a variable before properly defining it. Life lesson? You can’t build on what hasn’t been prepared. Clarity comes before execution. Foundation before speed. Definition before direction. Most frustrations both in code and in life come from skipping the basics. Slow down. Define things properly. Then move. If you code, you’ve definitely been here. #LifeLessonsFromCode #Python #LearningInPublic #TechLife #InsightAndForesight

Learning Python by Building Logic, Not Just Syntax Today I practiced a simple but important Python concept: list manipulation and edge-case handling. I wrote a small function that swaps the first and last elements of a list: 🔍 What this helped me understand: How Python handles indexing (0 and -1) Using tuple unpacking to swap values cleanly Why edge cases matter (empty or single-element lists) Writing logic that is safe, readable, and efficient Small exercises like this may look simple, but they build the foundations for real problem-solving, especially when working with data.
