Hi this is my first question on stack overflow, have a feeling I am going to use this site a lot more in future :/. Just learnt about lists today, and I read that popped elements of a list can still be operated on despite being removed so I tested it out with the code above, but I had an attribute error pop up. Why is this and how can I fix it?

Here is the error:

AttributeError: 'str' object has no attribute 'insert'

Thanks in advance whoever answers :)

You are storing string value in new_shopping_list. The new_shopping_list variable stores data which are pop from list not the whole list. You can use this snippet.

shopping_list = ['food','drinks']
shopping_list.pop(0)
print(shopping_list)
shopping_list.pop(0)
shopping_list.insert(0,'fruits')
print(shopping_list)

If you check type of new_shopping_list using type(new_shopping_list). it is a str. It does not have any attribute 'insert'. I think you wanted to insert in original list shopping_list

CodePudding user response：

If you delete : New_shopping_list=shopping_list.pop(0) And write: Shopping_list.insert(0,'friuts') Print(shopping_list) Will countinue easily without erorrs.
