It looks like there's a couple errors in your code. First off, in the place where you're defining x and y, it needs to be on separate lines. In other words, change
x = list(map(itemgetter('followers'), data)) y = list(map(itemgetter('name') ,data))
to
x = list(map(itemgetter('followers'), data))
y = list(map(itemgetter('name') ,data))
to be on separate lines. Also, since that is the only error in your code it looks like, what is it that you are trying to achieve with this code? Since when I run it, all it outputs is name : [['Brian'], ['Brian', 'Gosh', 'Anne'], []]  follow : ['Anne', 'Cindy', 'Dave']. Other than that, good luck with your programming adventures!
data = [{"name":"Anne", "followers":["Brian"]}, {"name":"Cindy", "followers":["Brian","G
osh","Anne"]},{"name":"Dave", "followers":[]}]
output :  [{"name": ["Brian"] , "follows":["Anne","Cindy"]},...] etc...
my code from now :
from operator import itemgetter
data = data = [{"name":"Anne", "followers":["Brian"]}, {"name":"Cindy", "followers":["Brian","Gosh","Anne"]},{"name":"Dave", "followers":[]}]
x = list(map(itemgetter('followers'), data))
y = list(map(itemgetter('name') ,data))
print("name : " + str(x), " follow : " + str(y))
