From Blocks to Text — Part 15
Same ideas in text code. This is part 15 of 20.
What you'll learn
You will learn to read text-based code and understand that syntax rules (spelling, colons, indentation) matter.
Steps
- 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!
