Python to sort out words in ascending order

sent = "mary has a very beautiful dog"
# Split on space.
my_arr = sent.split(" ")
print(my_arr)

# Create a new array using the sorted method
new_arr = sorted(my_arr)

print(new_arr)

# This time, my_arr won't change in place, rather, it'll be sorted 
# and a new instance will be assigned to new_arr
print(my_arr)
