Complete Python Programming Roadmap in 12 Weeks

✅ *Python Programming Basics* 🐍💻 *📌 Step 1: Install Python & VS Code* • Download Python 3.11+ from python.org • During install, check ✅ *Add Python to PATH* • Install *VS Code* • In VS Code, install the *Python* extension To check: Open terminal → Type: `python --version` You should see something like: `Python 3.x.x` *📌 Step 2: Your First Python Program* Create a file: `hello.py` Paste this code: ``` print("Hello, Python") ``` Run it in terminal: `python hello.py` 🧠 Python runs code top to bottom 🖨️ `print()` displays output on the screen *📌 Step 3: Variables* Variables store values. ``` age = 25 name = "Deepak" height = 5.11 print(age, name, height) ``` ✔️ No need to declare types — Python figures it out ✔️ Use lowercase names with underscores *📌 Step 4: Data Types* • `int` → Whole numbers (e.g., 10) • `float` → Decimals (e.g., 3.14) • `str` → Text (e.g., "hello") • `bool` → True / False To check type: ``` x = 10 print(type(x)) ``` *📌 Step 5: Input & Output* Take input from user: ```python name = input("Enter your name: ") print("Hello", name) ``` Convert string input to number: ``` age = int(input("Enter age: ")) print("Next year you'll be", age + 1) ``` *📌 Step 6: Arithmetic Operators* ``` a = 10 b = 3 print(a + b) # Add print(a - b) # Subtract print(a * b) # Multiply print(a / b) # Divide print(a // b) # Floor division print(a % b) # Remainder ``` *📌 Step 7: String Operations* ``` first = "Data" second = "Analyst" print(first + " " + second) # Concatenate print("Hi " * 3) # Repeat print(len(first)) # Length ``` *📌 Step 8: Practice Programs* 1️⃣ Simple Calculator → Input 2 numbers, show sum, difference, product, division 2️⃣ Temperature Converter → Input Celsius, convert to Fahrenheit `F = (C * 9/5) + 32` 3️⃣ Age After 5 Years → Input current age, print age after 5 years Here is the detailed code for each project: 📌 *Project 1. Simple Calculator* ``` num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) print("Addition:", num1 + num2) print("Subtraction:", num1 - num2) print("Multiplication:", num1 * num2) if num2 != 0: print("Division:", num1 / num2) else: print("Division not possible") ``` 📌 *Project 2. Temperature Converter (Celsius to Fahrenheit)* ``` celsius = float(input("Enter temperature in Celsius: ")) fahrenheit = (celsius * 9 / 5) + 32 print("Temperature in Fahrenheit:", fahrenheit) ``` 📌 *Project 3. Age After 5 Years* ``` age = int(input("Enter your age: ")) future_age = age + 5 print("Your age after 5 years:", future_age) ``` 🎁 *Bonus Practice – Area of a Rectangle* ``` length = float(input("Enter length: ")) width = float(input("Enter width: ")) area = length * width print("Area of rectangle:", area) ```

Day 57 of my Python Journey 👨🏽💻 🔥 Modular Programming & Data Persistence! 🔥 I kicked off today with the intention of building more advanced projects using the concept of python modules and i challenged myself by building a functional Phone Book✨. Building this wasn't easy 😅 because I tried to replicate a simple phonebook project i built in the past using only python dictionaries and i faced a persistent problem anytime I ran the code 😤💔, Any new contact i input kept disappearing after i exit PyCharm. So I did a little research and found out about python's built-in function called JSON which turned out to be a life saver 😅😃 How it was written 👇🏽 📁 Started by creating the module file that contains logic (PhoneBook.py) which handles the backend operations—creating, reading, and clearing data. In this file: ~ I imported "json" which is a built-in python library used to save data to a file and load it back later🔥, FILE_NAME = "contacts.json" defines the file name as a constant. ~ Then I defined a function named loadContacts() that attempts to open the JSON file in read mode ("r"). if u watch the video you would find a function written beneath it called json.load(file) that converts the inputted user text inside the file back into a usable dictionary. ~ saveContacts(contacts) was also defined and it is the function that opens the file in write mode ("w"). This overwrites the existing file with new data using json.dump() ~ The addContact(contacts, name, phone) function adds a new key-value pair (Name -> Number) to the dictionary. ~ saveContacts(contacts) immediately saves the updated dictionary to the file so data isn't lost and clearContacts() calls back saveContacts({}) passing an empty dictionary in it {} which effectively overwrites the file thereby deleting all contacts ✅ 📁 The second file (main.py) which is the interface and easiest to write 😅 simply handles the user experience (input/output) and menu loop ✨.main.py generally takes the input and calls the recquired functions for updating, deleting and saving of data. I'm glad i was able to successfully make the data persistent. Even if the program closes, the contacts remain saved ✨🔥😚 It feels so rewarding to build with already learned concepts and see the projects come alive. Seeing how modules interact with one another and gave me a much clearer understanding of how real-world software is structured ✨..
