Python Access Array Item - GeeksforGeeks

In this article, we will explore how to access array items using the array module in Python. Once array is created, we can access its items just like accessing elements in a list. Here are some ways to access array items: Arrays in Python are zero-indexed. The first element is at index 0, the second at index 1 and so on.

5 Easy Ways To Extract Elements From A Python List

Here, we used the numpy import function to print the index specified in variable ‘sx’ from the elements present in list ‘ax’ using np.array library function. This example uses variable storing index positions and another variable storing numbers in an array.

numpy.extract — NumPy v2.2 Manual

Return the elements of an array that satisfy some condition. This is equivalent to np.compress(ravel(condition), ravel(arr)). If condition is boolean np.extract is equivalent to arr[condition]. Note that place does the exact opposite of extract. An array whose nonzero or True entries indicate the elements of arr to extract.
