From Blocks to Text — Part 8

See how block code maps to text code.

What you'll learn

You will learn to read text-based code and understand that syntax rules (spelling, colons, indentation) matter.

Words to know

Text code: Code written as words and symbols. Python is text code. Spelling and indentation matter.
Syntax: The rules for how to write code correctly (colons, indentation, etc.).
Indent: Adding spaces at the start of a line. Code inside a loop or if must be indented.

Try it: run the code, then change it

1This is text-based code (not block-based). You type it out with words and symbols. Spelling and spacing matter!
2Notice the colon : after range(3) and the indentation (spaces) before print. These are Python's syntax rules.
3The loop runs 3 times. The output would be: Line 1, Line 2, Line 3, Done. Can you trace through it?
4Reading code is a skill. Practice by going line by line and predicting what the output would be BEFORE checking!

Auto-run is on: change the code and the result updates by itself.
