Welcome to the Journey!
Today marks Day 1 of your ambitious 100-Day Python Adventure! You’ve made the decision to learn the most versatile and in-demand programming language in the world, and that’s a huge step. Give yourself a moment to celebrate. You're officially a coder.
The first step in any epic journey is always the simplest, yet the most foundational. It’s a moment of proof, a confirmation that you are ready.
Your Very First Program
Every coder, from the creator of Python to the engineers at Google, starts here: with "Hello, World!"
This program confirms three things:
- Python is installed correctly.
- You know how to open your interpreter or code editor.
- You can execute a command.
The Action:
To run your first program, all you need is the print() function. This is your code’s voice—the way it speaks back to you.
Type the following line exactly as you see it into your Python interpreter, terminal, or code editor:
print("Hello, World!")The Result:
When you hit Enter or run the script, your screen should proudly display:
Hello, World!💬 What's Next?
That tiny command is your official launch. It’s proof of concept, and it opens up a world of possibilities.
Over the next 99 days, we will move from this single line to mastering:
- Storing information with Variables and Data Structures (Lists, Dictionaries).
- Giving your programs intelligence with Logic and Control Flow (
if/else,forloops). - Writing reusable, clean code with Functions.
- Interacting with the real world using Files and Modules.
Your Challenge for Day 1:
What are you hoping to build in the next 100 days? A website? A data analysis tool? A simple game? Share your goal in the comments below!
This journey won't always be easy, but it will be rewarding. Let's make every day count!
