Answer from AI
In Python, the main differences between list (list) and array (array) are:
-
Data types of elements:
listcan contain elements of different types (numbers, strings, objects).arrayfrom thearraymodule is designed to store elements of the same type, which saves memory and speeds up operations.
-
Performance:
- Arrays generally work faster and occupy less memory when working with large volumes of homogeneous data.
-
Functionality:
- Lists are more versatile and have more built-in methods.
- Arrays are limited in functionality but support efficient numerical operations.
Example of creating an array:
import array
# Array of integers
arr = array.array('i', [1, 2, 3, 4])
Example of a list:
lst = [1, 'two', 3.0, True]
In Flutter (Dart), lists (List) are dynamic collections, and there is no separate array type.
