Question
Write the recursive version of the function filter which returns a list and takes in
f - a one-argument function that returns True if the passed in argument should be included in the
resulting list or False otherwise
seq
seq- a list of values
.
Note that this is different from the built in filter function we learned previously, which returns a filter
object, not a list.
def filter (f, seq):
"""Filter a sequence to only contain values allowed by filter.
>>> def is_even(x):
return x % 2 == 0
>>> def divisible_by5(x):
return x % 5 == 0
>>> filter (is_even, [1,2,3,4])
[2, 4]
>>> filter (divisible_by5, [1, 4, 9, 16, 25, 100])
[25, 100]
