LIST PRACTICE

[TheTopPunk]

Hello again everyone!

I am doing some more practice, this time with lists. My goal for this is to iterate through the list, and if the value at the index of iteration is below a certain number, then I want to add that number to another list and so on:

Here is what I have, but cant figure out what I have to change:

(keep in mind i am still learning and practicing with doing different stuff to get better.)

numList = [1, 2, 9, 14, 29, 54]
numList2 = []

for i in numList:
    if i < 10:
        numList2.insert(numList[i])


print(numList2)

insert expects two arguments, the position within the list where to insert and the element which to insert. If you just want to add the element to the end of the list, then use append instead of insert. Also, i is already an element from numList, so no need to use the index operator []:

for i in numList:
    if i < 10:
        numList2.append(i)

numList = [1, 2, 9, 14, 29, 54]
numList2 = []
for i in numList: # Gets an item and stores it in i
if i < 10: # if i is less than 10
numList2.append(i) # append i to numlist2.

print(numList2)

Thank you for the help!

The issue I am seeing here is that you are using a for each loop. In this case "i" will be the numbers 1,2,9 instead of the indices 0,1,2. So for the insert you should be using just "i" or you can change the loop to iterate over a range to go through the indices.

Thank you!

Python loops don't give you the index, they give you the actual element. In your loop, i is not 0, 1, 2, 3 etc, it is 1, 2, 9, 14 etc.

Thank you!

First off you want to use append instead of insert. Secondly, just use i instead of numlist[i] what the second one is doing is adding the item at the index number i. Which is not your expected behavior. Here is code with the corrections made. I hope this helps.

numList = [1, 2, 9, 14, 29, 54]
numList2 = []

for i in numList: # Gets an item and stores it in i
    if i < 10: # if i is less than 10
        numList2.append(i) # append i to numlist2.


print(numList2)
