Context basics

  • Use with for resources.
  • Bind names with as.
  • Keep cleanup automatic.

With statements

Open files or resources and let Python handle cleanup automatically.

context.pln 
with open("data.json", "r") as file do data = json.load(file)

Multi-line context blocks

Use indentation when the context block needs multiple steps.

context_block.pln 
with open("report.txt", "w") as handle do
    handle.write("Summary")
    handle.write("\nDone")

Context tips

  • Always use with for file access.
  • Keep context blocks small and focused.
  • Combine with error handling for safe IO.
