I take it "map" is just a built in python function/method?

Haven't had a chance to finish reading but will do so soon

(http://www.autoadmit.com/thread.php?thread_id=3675368&forum_id=2#33777941)

names = ["Alice", "Bob", "Carol"]

def length_string(x):

return len(x)

result = map(length_string,names)

print(list(result))

2.

numbers = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ]

def sum_nums(x):

return x[0]+x[1]+x[2]

result = map(sum_nums,numbers)

print(list(result))

3.num = [2, 3, 4, 5, 6, 7, 8, 9, 10]

def check_prime(x):

y = 2

if x <= 3:

return "true"

while x / y >= 2:

if x % y == 0:

return "false"

y = y + 1

return "true"

result = map(check_prime,num)

print(list(result))
