Python Code Challenges: Lists (Advanced) 4th

Hello!
I am doing Python Code Challenges: Lists (Advanced) 4th, given solution code was like this:

def double_index(my_list, index): # Checks to see if index is too big if index >= len(my_list): return my_list else: # Gets the original list up to index my_new_list = my_list[0:index] # Adds double the value at index to the new list my_new_list.append(my_list[index]*2) # Adds the rest of the original list my_new_list = my_new_list + my_list[index+1:] return my_new_list

Mine solution was like this:

#Write your function here def double_index(my_list, index): if index >= len(my_list): return my_list else: num = my_list[index] * 2 my_list.insert(index, num) my_list.pop(index+1) return my_list #Uncomment the line below when your function is done print(double_index([3, 8, -10, 12], 2))

Does anyone see any problem that may arise with my code? Or why should I do it like the given solution? It is my 6th day learning this, so I’m checking with experienced people.

Specification:

The function should return a new list

``````# Solution Code:
x = [3, 8, -10, 12]
y = double_index(x, 2)

print(y) # [3, 8, -20, 12]
print(x) # [3, 8, -10, 12]
# Original List is unchanged
