ALT the output of these inputs {1, 2, 3, 4, 5} Add the new value in set {1, 2, 3, 4, 5, 6} remove the value from the set {1, 2, 3, 4, 5} find the unoin of both set a and b {1, 2, 3, 4, 5, 6, 7} find the intersection of a and b {1, 4} True True PS C:\Users\shahz\Desktop\python basic

ALT Summary Table: Method What It Does Example Use Case append() Add item to the end Add a new entry to a user list sort() Sort values in ascending order Organize scores, names, dates reverse() Reverse the current order of list Flip a list to see recent data first insert() Add item at a chosen index Insert value at 3rd position pop() Remove item at specific index Remove last added cart item remove() Remove item by value (not by index) Delete unwanted or duplicate value

ALT oday I learned how indexing works in Python strings 🧠 👉 Indexing means accessing specific letters from a word using position numbers 👉 Python always starts counting from 0 🔹 a[4] → Gives the 5th letter of the word (because index starts at 0) 🔹 name[2:4] → Slices letters from index 2 to 3 (4 is not included) 🔹 name[3] → Gives the single letter at index 3 📌 This is useful for: Working with names, usernames, text, passwords Filtering and editing characters Building smart string functions

ALT Topic: String Slicing & Negative Indexing in Python Today I learned how to access parts of a string using both positive and negative indexes in Python: 📌 Key Concepts: string[start:end] → returns characters from start to end-1 string[-n] → accesses characters from the end of the string [:end] → from start to end-1 [start:] → from start to the end of string 🧠 Why It Matters: Understanding string slicing is useful for: Cutting parts of names, emails, or text Masking or reversing strings Cleaning or analyzing text data in real projects

ALT Today I explored the basics of Python: ✅ Printing and Type Checking ✅ Type Casting (converting strings to numbers) ✅ Arithmetic & Assignment Operators ✅ Comparison Operators (==, !=, <, >) ✅ Logical Operators (and, or, not) with Truth Tables ✅ Compact Caption-Style Explanation: 🧠 What I learned in Day 1 of Python: ✅ type() function – It tells you what kind of value a variable holds (like int, float, or string). ✅ Type Casting – Changing data from one type to another, like string "5" to integer 5 using int() or float(). ✅ Arithmetic Operators – Used for basic math like , -, *, and /. ✅ Assignment Operators – Let you update values, like b = 3 means b = b 3. ✅ Comparison Operators – Compare values using ==, !=, <, >, and return True or False. ✅ Logical Operators – Combine conditions using and, or, and not. ✅ Truth Tables – Help you understand how logic works with True/False values. These are the building blocks of Python logic — very important for writing real programs
