Advantages of Arrays
The following are some advantages of arrays:
-
Arrays are similar to lists. The main difference is that arrays can store only one type of elements; whereas, lists can store different types of elements. When dealing with a huge number of elements, arrays use less memory than lists and they offer faster execution than lists.
-
The size of the array is not fixed in Python. Hence, we need not specify how many elements we are going to store into an array in the beginning.
-
Arrays can grow or shrink in memory dynamically (during runtime).
-
Arrays are useful to handle a collection of elements like a group of numbers or characters.
-
Methods that are useful to process the elements of any array are available in 'array' module.
