When we applynp.argsort()in Python to an array, it computes the indices of the array’s elements in sorted order. However, it’s important to note that it does not change the original array. Instead, it provides a way to access the elements in the order that would sort the array in...
When you’re working with an array, each “dimension” can be thought of as an axis. This is sort of like the Cartesian coordinate system, which has an x-axis and a y-axis. The different “directions” – the dimensions – can be calledaxes. ...
