What Python is good at here
Tiny tools. Questions and answers. Reading a battery number. Writing a to-do line into a file. All of that can live in Termux.
What it is not: the usual language of Play Store apps. Those later rooms speak Kotlin or Java.
First language
A .py file is just text with a label on the end.
Python is a recipe format the computer already knows. You will start with print, input, and a sticky note called a variable. If, loops, lists, and functions wait for weeks 2 and 3. This page does not dump them.
Sticky notes
Tap a note. The value changes. That is all a variable is: a labeled scrap that can hold a new thing later.
The first three lines
print shows text.
input asks a question and waits.
name = ... parks the answer on a sticky note.
Later, not now
Week 2: if/else (choices), loops (repeat this), lists (a row of sticky notes). Week 3: functions (a named mini-recipe) and files. Come back to those words when a practice page names them.
Next step
JSON is packed data, not an app language.
