Lo-Dash Differences¶

Naming Conventions¶

pydash adheres to the following conventions:

Function names use snake_case instead of camelCase.
Any Lo-Dash function that shares its name with a reserved Python keyword will have an _ appended after it (e.g. filter in Lo-Dash would be filter_ in pydash.
Lo-Dash’s toArray() is pydash’s to_list().
Lo-Dash’s functions() is pydash’s callables(). This particular name difference was chosen in order to allow for the functions.py module file to exist at root of the project. Previously, functions.py existed in pydash/api/ but in v2.0.0, it was decided to move everything in api/ to pydash/. Therefore, In to avoid import ambiguities, the functions() function was renamed.

There are a few differences between extra callback style support:

Lo-Dash’s property style callback form uses shallow property access while the same form in pydash uses deep property access via the deep path string.
Pydash has an explicit shallow property access of the form ['some_property'].

In addition to porting Lo-Dash, pydash contains functions found in lodashcontrib, lodashdeep, lodashmath, and underscorestring.

Some of pydash’s functions behave differently:

pydash.utilities.memoize() uses all passed in arguments as the cache key by default instead of only using the first argument.
