🚀 Day 29/100 | #100DaysOfCode — Python Learning Journey 🐍 Today I explored two very important file handling methods in Python: 👉 tell() and seek() — and they completely changed how I think about reading files 📄➡️🧠 Here’s what I learned today 👇 🔹 tell() — Where am I in the file? tell() helps to find the current position of the cursor inside the file. It tells us exactly where Python is reading or writing from. 🔹 seek() — Let’s move the cursor With seek(), we can move the file pointer to any position we want. This means we can re-read data, skip data, or jump to a specific part of the file. 🔹 Why this matters Now I understand how Python controls from where to read and where to write in large files — which is super useful in real projects. Small concepts, but very powerful when building real applications 💡🔥 Still learning. Still showing up. One step closer every day 💪 👉 Trust the process. Keep coding. #Python #FileHandling #tell #seek #100DaysOfCode #LearningInPublic #CodingJourney #Consistency

How Python Uses Data Structures Behind the Scenes: Lists, Tuples, Sets, and Dictionaries When I first started learning Python, I saw data structures as simple storage tools. Lists grouped items, dictionaries mapped keys to values, sets removed duplicates, and tuples looked like fixed lists. That understanding worked for small programs, but not for writing efficient solutions. While preparing for placements and solving coding problems, I noticed something important: correct logic is not enough. Performance matters. Many of my solutions were slow because I chose the wrong data structure. Once I understood how Python handles these structures internally, my approach changed. Lists are implemented as dynamic arrays. They are ordered and mutable, which makes them flexible. Accessing elements by index is fast, but searching repeatedly in large lists can slow things down. Tuples are immutable. Because they cannot change, they are more stable and slightly memory-efficient. They are ideal for fixed data like coordinates or configuration values. Sets use hashing internally. This allows extremely fast membership checking and automatically removes duplicates. Switching from list-based searching to sets improved the efficiency of many of my solutions. Dictionaries also use hashing. They store data as key-value pairs and provide fast lookups. That’s why they are widely used for frequency counting, structured data storage, and backend systems. Understanding these internal concepts helped me start thinking differently while coding. Instead of asking “Does this work?”, I began asking: Does order matter? Do I need uniqueness? Do I need fast lookups? Should this data remain constant? That small shift improved both my code quality and performance. Python keeps things simple on the surface, but powerful underneath. Learning what happens behind the scenes is what truly helps you grow as a developer. 🔗 Read the full article here: https://lnkd.in/gN9UXiwT #Python #DataStructures #Programming #SoftwareDevelopment #LeetCode #CodingInterview #LearningInPublic #TechBlog #BackendDevelopment #InnomaticsResearchLabs

🚀 Revisiting Python Fundamentals Day 6: Flow Control Statements in Python In Python, code normally executes line by line from top to bottom. But real-world programs need more than that. They need to: Make decisions Repeat actions Control execution flow That’s where Flow Control Statements come in. Flow control statements decide which block of code runs and how many times it runs. They are mainly divided into three categories: 🔹 1️⃣ Decision Statements These are used when a program needs to choose between alternatives. Python provides: if elif else Example: age = 18 if age >= 18: print("Eligible to vote") else: print("Not eligible") Here: Python checks the condition age >= 18 If it is True, the first block runs If False, the else block runs Decision statements allow programs to behave differently based on conditions. 🔹 2️⃣ Looping Statements Loops are used when a block of code needs to run multiple times. Python provides: for while For Loop Used when the number of iterations is known. for i in range(3): print(i) This prints values from 0 to 2. While Loop Used when execution depends on a condition. count = 0 while count < 3: print(count) count += 1 The loop runs until the condition becomes False. Loops reduce repetition and make programs efficient. 🔹 3️⃣ Control Statements These are used inside loops to change their normal behavior. break → immediately exits the loop continue → skips the current iteration pass → placeholder that does nothing Example using break: for i in range(5): if i == 3: break print(i) The loop stops when i becomes 3. #Python #FlowControl #PythonBasics #LearnPython #Programming
