If the values are strings, an alphabetically comparison is done. Python Array maximum. This is where the argmin and argmax functions that are specific to NumPy arrays come in. Here we converted the numpy arr to another array by picking values from two different lists based on the condition on original numpy array arr. The arguments of NumPy arange() that define the values contained in the array correspond to the numeric parameters start, stop, and step. In other words, you may need to find the indices of the minimum and maximum values.

NumPy Random Object Exercises, Practice and Solution: Write a NumPy program to create a 5x5 array with random values and find the minimum and maximum values. In case of multiple occurrences of the maximum values, the indices corresponding to the first occurrence are returned. The return value of min() and max() functions is based on the axis specified. I would like a similar thing, but returning the indexes of the N maximum values. The max() function returns the item with the highest value, or the item with the highest value in an iterable.. So, let’s directly jump into the example. The min() and max() functions from the NumPy library help you find the minimum and maximum values in NumPy arrays, respectively. finfo (dtype). You have to pass at least one of them. Numpy proposes a way to get the index of the maximum value of an array via np.argmax.. max_value = numpy.amax(arr, axis) If you do not provide any axis, the maximum of the array is returned. In this video, learn how to use NumPy's min() and max() functions when working with NumPy arrays. >>> This one is pretty simple. To get the indices of the four largest elements, do >>> a = np.array([9, 4, 4, 3, 3, 9, 0, 4, 6, 0]) >>> ind = np.argpartition(a, -4)[-4:] >>> ind >>> a[ind] Related questions +1 vote.
