Log Parser in Python

MediumPython

Problem

Write a log parser in Python.

Asked in the Technical Evaluation stage.

Implement parse_logs(lines). Each valid line has the format <timestamp> <level> <message>, where timestamp is an ISO-8601 UTC value ending in Z, and level is one of INFO, WARN, ERROR, or DEBUG. Return a dictionary containing valid parsed records in input order, counts by level, and the number of malformed lines. Ignore malformed lines rather than raising an exception.

Constraints

1 <= len(lines) <= 1000
Each line contains at most 500 characters
A valid timestamp uses the form YYYY-MM-DDTHH:MM:SSZ
Valid levels are INFO, WARN, ERROR, and DEBUG
A valid message contains at least one character
