Today I got a lesson to learn about array in Python 3.8.2. And I create an int array and I want to insert more items into it.
import array as arr
a = arr.array('i', [1, 2, 3])
a.insert[4, 5]
But I got an error: TypeError: 'builtin_function_or_method' object is not subscriptable
Traceback (most recent call last):
File "main.py", line 3, in <module>
a.insert[1, 4]
TypeError: 'builtin_function_or_method' object is not subscriptable
I don't know why the error occurs!!
Thanks for any suggestions.

I think you need to check again syntax of the array.
Syntax:
list_name.insert(index, element)
Parameters:
- index: the index at which the element has to be inserted.
- element: the element to be inserted in the list.
import array as arr a = arr.array('i', [1, 2, 3]) a.insert(3, 4) // 1st: index of array, 2nd: value of index.I hope it helpful for you!!

You can use
append()method:import array as arr a = arr.array('i', [1, 2, 3]) a.append(4) print(a[3]) # output 4seems easy!!
