Today, let's start with the first topic in Python Programming Roadmap:
✅ 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)
💡Useful Tips
* Run each program
* Change input values
* Break it on purpose and fix it
🧠 Daily Rule:
* Code at least 60 mins
* Type every line manually
* Don’t copy-paste — build muscle memory
I have decided to give some quizzes after this post to test your knowledge
