Example 1 : argmax() Function in One-Dimensional Array The following code uses the argmax() function from the NumPy package to return the index of the largest value in the one-dimensional array named "my_array". In this array, the maximum value is 10 which lies at the 2nd index. Keep...

The Numpy argmax function often confuses people, but it starts to make sense once someone explains it clearly (which I’m going to try to do). Essentially, the argmax function returns the index of the maximum value of a Numpy array. It’s somewhat similar tothe Numpy maximum function, b...
