Hey everyone!

During the exercise n° 4 of the Python Code Challenges: Lists (Advanced), I found probably another solution to solve the exercise in a more easier way (I’m a newcomer to Python3, so I’m not so sure ).

The original solution was:

```
def double_index(lst, index):
# Checks to see if index is too big
if index >= len(lst):
return lst
else:
# Gets the original list up to index
new_lst = lst[0:index]
# Adds double the value at index to the new list
new_lst.append(lst[index]*2)
# Adds the rest of the original list
new_lst = new_lst + lst[index+1:]
return new_lst
print(double_index([3, 8, -10, 12], 2))
```

And my solution is:

```
def double_index(lst, index):
if index + 1 <= len(lst):
lst[index] *= 2
return lst
print(double_index([3, 8, -10, 12], 2))
```

Someone can review this few lines of code?

Thank you very much in advance.

Have a nice day
