Python Array Indexing - GeeksforGeeks

We can access elements from the beginning of the array using positive indices: Let's explore python array indexing in detail: In Python, arrays support negative indexing where the last element of the array is accessed with index -1, the second-to-last element with index -2 and so on. Here's an example: Explanation:

Modify the value of the first array item: Use the len() method to return the length of an array (the number of elements in an array). Return the number of elements in the cars array: Note: The length of an array is always one more than the highest array index. You can use the for in loop to loop through all the elements of an array.
