Can anyone list down different methods to find the ‘nth’ largest values using NumPy only? I wanted to implement this functionality in my code assignment but I am facing an issue to implement this using NumPy, the only method I do know of is how to extract the ‘nth’ largest value using a Python for loop (pasting below for reference), which is not efficient at all.

Hello @safiaa.02, if you want to find the n
largest values in a NumPy array using NumPy, you can use the np.sort()
function along with array slicing. Here is an example code that finds the 3
largest values in an array:
- The
np.sort()
function sorts the array in ascending order by default. - To get the largest values, the code reverses the sorted array using the
[::-1]
slicing syntax. - Finally, the first
n
elements of the reversed array are selected to get then
largest values.
I hope this code helps!
