where

where(predicate)

The where method applies the predicate lambda expression as a filter in the Enumerable collection. This method is not an executing function.

Parameters:

predicate: lambda expression that is used to test each element for a condition.

Returns:

An Enumerable object that contains elements from the input sequence that satisfy the condition.

Example

from py_linq import Enumerable

marks = Enumerable([25, 49, 50, 80, 90])
passing = marks.where(lambda x: x >= 50) # results in [50, 80, 90]
