using map function

[DeaD_EyE]

The first argument of map is the function which is called repeatedly with the elements of the iterable. Don't call the function when you pass it to a map function.

def name_split(name):
    return name.split()

people = ['Dr. Christopher Brooks', 'Dr. Kevyn Collins-Thompson', 'Dr. VG Vinod Vydiswaran', 'Dr. Daniel Romero']
splitted_names = list(map(name_split, people))
print(splitted_names)
