Build Dynamic Log Filters with Loguru Callables

Problem

Logging is informative, but unnecessary logs can distract from the important ones. While you can filter by log level, sometimes you need to filter by some specific metric values.

Solution

Loguru allows you to add a custom callable filter to your logger based on your specific criteria. This is significantly easier than setting up a custom filter class with standard logging.

Other features of Loguru:

• Beautiful logging output out of the box
• Significantly simpler to use than standard logging
• Rich exception tracebacks with variable values

Whenever: Python DateTime Done Right

Problem

Standard library datetime arithmetic ignores Daylight Saving Time (DST) transitions, producing incorrect results.

Your time calculations can be off by an hour during DST changes.

Solution

Whenever’s ZonedDateTime automatically accounts for Daylight Saving Time during time calculations.

Why use Whenever:

• Type-safe datetime operations prevent mixing errors
• DST transitions handled automatically (no surprises)
• Faster performance than standard library, Arrow and Pendulum
• Drop-in replacement for standard library
