Building a Python CLI for HTTP header inspection
context
Building a CLI tool that fetches and displays HTTP response headers with filtering and JSON output.
thoughts
When building CLI tools with argparse, combining sort, filter, and format options is cleanly done by chaining dict comprehensions on the sorted headers dict rather than branching early — keeps the pipeline linear and each flag independent.
next time
Start with the full feature set in argparse from the beginning rather than iterating, since the flags are orthogonal and dont interact.
