NumPy provides powerful tools for data processing and filtering. In this article, we will explore some essential techniques that can help you efficiently manipulate and filter data using NumPy arrays.

Sorting: One common task in data processing is sorting the elements of an array. NumPy provides a sort function that can sort arrays along a specific axis. For example, if we have a 2D array arr, we can sort its rows by calling np.sort(arr).

Averaging: Another important operation is calculating the average of an array. NumPy offers the mean function to compute the mean along a specified axis. Suppose we have a 1D array data, we can find its average by calling np.mean(data).

Filtering: Filtering allows us to extract specific elements from an array based on certain conditions. NumPy provides a powerful method called boolean indexing, which allows us to create a boolean array based on a condition and then use it to filter the data. For example, to filter out all the values greater than 5 from an array arr, we can use the expression arr[arr > 5].

These are just a few examples of the data processing and filtering capabilities in NumPy. By mastering these techniques, you can efficiently manipulate and filter your data with ease.

Remember, practice makes perfect! Keep exploring and applying these techniques to solve real-world problems. Happy coding!
