Python provides 3 useful global functions we can use to work with collections:
Tip: sometimes list comprehensions make more sense and are generally considered more pythonic
filter() takes an iterable and returns a filter object, which is another iterable, but without some of the original items.
You do so by returning
False from the filtering function:
numbers = [1, 2, 3] def isEven(n): return n % 2 == 0 result = filter(isEven, numbers) print(list(result)) # 
You can use a lambda function to make the code more concise:
numbers = [1, 2, 3] result = filter(lambda n: n % 2 == 0, numbers) print(list(result)) #
