Must-do problems: Files and Data Formats

75 min · Beginner

The judge gives your program only standard input, so these problems read CSV or JSON text with input() and use the same modules you use for files. Parse the text, convert the values, then print the answer. Check each program against the edge cases before you move on.

What you will learn

Parse CSV text with the csv module, including quoted commas
Parse and build JSON text
Convert between CSV and JSON
Handle invalid JSON without crashing
