Nano

What is Nano?

Think of Nano as a notebook inside Termux — but a special kind of notebook.

It’s where you can write your Python code and save it as a file.

Let me explain it in a way that feels super easy.

Example Story:

Let’s say you open Termux and type your Python directly:

python

Then inside Python you type:

print("Hello, Dimma!")

That works! But when you close Termux, that code disappears — it’s not saved anywhere.

So, what if you want to save your code and come back to it later?

That’s where Nano comes in!

Nano helps you:

Create a file (like a notebook),

Type your code inside it,

Save it to your phone,

Run it anytime later.

How Nano Works (step by step):

1. In Termux Type:

nano my_first_code.py

What this means:

nano = open the Nano text editor

my_first_code.py = the name of your new file

(the “.py” part means it’s a Python file).

2. Now, Termux will open a blank page — that’s your coding notebook.

You can start typing your Python code inside it, like:

print("Hello, Dimma!")

print("Welcome to Python")

3. When you’re done typing, press:

CTRL + O → (to “write out” or save your work)

Then press Enter → (to confirm the file name)

Then press CTRL + X → (to exit Nano and go back to Termux)

4. Now, your file is saved!

To run it, type:

python my_first_code.py

And you’ll see:

Hello, Emelda!

Welcome to Python

So, simply put:

Tool & What it does:

• Termux - Lets your phone behave like a computer.

• Python - The language you’ll use to tell your computer what to do.

• Nano - Simple text editor where you write and save your Python programs.

So you can think of Nano as:

“The paper where you write your code before you run it.”
