Comment

As explained in Learn AI-Assisted Python Programming, Second Edition

A source-code annotation that is ignored during program execution and can provide human-readable information or instructions.

A comment is source-code text that the computer ignores during execution. Programmers use comments to summarize code for people, and tools such as Copilot can also use them as instructions for generating code. section 2.6.1

Describe an output task

Write `# output "Hello Copilot" to the screen` above `print("Hello Copilot")`. The first line documents the task without executing, while the second line performs it. section 2.6.1

# output "Hello Copilot" to the screen
print("Hello Copilot")

Compare a human-readable comment with the executable statement it helps describe. section 2.6.1

How Learn AI-Assisted Python Programming, Second Edition covers it

How deep it goes
Defines execution behavior, human-readable summaries, and Copilot prompting, without descending into language implementation details.
Examples
Uses hash-prefixed output instructions alongside Python print statements, including a Hello Copilot example.
What it assumes
Starts from zero by explaining the hash marker and distinguishing comments from executable code.
What you can do after
Apply comments to document Python code and prompt Copilot with plain-language programming instructions.
How it connects
Ties comments to source code, program execution, Python, VS Code, and code completion.
