Python's filter is a built-in function that allows you to process an iterable and extract those items that satisfy a given condition. This process is commonly known as a filtering operation. With filter, you can apply a filtering function to an iterable and produce a new iterable with the items that satisfy the condition at hand. In Python, filter is one of the tools you can use for

The python filter function is a built-in function that filters the given sequence with the help of a function that tests each element in the sequence to be true or not. In this tutorial we learned about the python filter method, starting from getting familiar with its syntax to solving different examples using the filter function.

The lambda function returns true if the number is even, else it returns false.. When to Use the Built-in Filter Function. The built-in filter function takes two arguments a function and a list..

Basic usage of filter. The first argument of filter is a callable object such as a function to be applied, and the second argument is an iterable object such as a list.

iterable The iterable you want to filter e.g., list, tuple, set. The result is a filter object, which can be converted into a list, tuple or another iterable type. Let us see a few examples of the filter function in Python. Using filter with lambda. For concise conditions, we can use a lambda function instead of defining a named function
