Have you ever written Python code like this?

To extract a deeply nested value from a dictionary or JSON data, we’re forced to write long, unwieldy chains of safety checks. This is not only error-prone but also extremely difficult to read and maintain.

If you find the above scenario utterly frustrating, then glom this is the savior you’ve been searching for.

glom is a third-party Python library that provides a function called glom, along with a series of powerful operational patterns. Its core mission is singular: to make processing nested data in Python declarative, intuitive, and safe.

“Declarative” means you only need to tell glom what you want, rather than instructing it step-by-step on how to do it, like imperative code does. This greatly enhances code conciseness and readability.
