Can anyone help?. Why does the code below outputs an error ? itm = [] itm [0] = "cat" print (itm)

Question

Updating an empty list

Answer 1

The way you initialized this list, it has no slots available. It prints an error because itm[0] is not a place in the list yet. To add a slot to this list, use itm.append("cat"). Now you can also do itm[0] because its available in the list.

Thank you all for the quick response 👍

Answer 3

~ swim ~ I found out that itm.append("cat") and itm += "cat"
aren't all that thesame.
I checked with this code.

words = ["hello", "world", "spam", "eggs"]
itm = []
itm2 = []
for a in words :
itm += a
itm2.append(a)
print (itm)
print (itm2)
