why do we need the for loop before the .insert() statement?

Hello Bhaktipriya,

Suppose you put multiple items in your new_list. If we don't loop over the new_list and write .insert(spot, new_list) instead, we will just insert the whole list (as a complete list) into the shopping_list. This will give problems later on, I think, when we want to print our shopping_list. The .insert(spot, item.strip()) will be executed multiple times, one time for every item in our new_list. For example when the shopping_list is ['banana', 'pear'] and we would like to insert the new_list ['apple', 'peach'] into the shopping_list on spot 1, then we will first get ['banana', 'apple', 'pear'] on the first iteration and then ['banana', 'peach', 'apple', 'pear'] on the second iteration. If we don't include the for-loop but just write .insert(spot, new_list) we would get ['banana', ['apple','peach'], 'pear'].
