Python Roadmap

Before you start: A terminal and a text editor.

Build or practice: Filter unhealthy servers from a CSV file.

• Explain mutable and immutable values.

• Check empty, malformed, and missing input.
• Explain the expected output and failure behavior.

Before you start: Finish the production scripting bridge and EC2 report lab.

Build or practice: Extend the inventory reporter to a second region.

• Read all response pages.
• Keep credentials outside source code.
• Set timeouts and bounded retries, and return a failure exit code.

Before you start: Comfort reading and testing automation scripts.

Build or practice: Investigate a slow or failing service and explain the evidence.

• Reproduce a failure before changing code.
• Separate transient failures from invalid requests.
• Propose a fix and a test that catches a regression.

Before you start: Attempt the chapter knowledge checks first.

Build or practice: Answer a quiz without notes and explain each missed answer.

• Explain why an answer is correct.
• Identify and revisit weak topics.
• Apply the corrected concept in a small script.

Before you start: Complete one end-to-end project and scenario.
