Python filter(lambda)

  • by

Python filter(lambda) is possible because you can use the Lambda function inside the filter() built-in function. The filter method filters elements from an iterable that meets a specific condition.

The lambda functions inline and anonymous functions in Python. These functions can be used along with the filter method.

filter(lambda x: x , inp_list)

Python filter lambda example

Simple example code filters all the values from the list that is less than or equal to 20. Each value of the list is passed to the lambda function. If it returns True, the value is added to the result; otherwise, not.

lst = [11, 23, 13, 4, 15, 66, 7, 8, 99, 10]
res = list(filter(lambda x: x <= 20, lst))
