Explanation:
Detailed explanation-1: -ptp() The numpy. ptp() function returns the range (maximum-minimum) of values along an axis.
Detailed explanation-2: -Python provides different inbuilt function. min() is used for find out minimum value in an array, max() is used for find out maximum value in an array. index() is used for finding the index of the element.
Detailed explanation-3: -The numpy. argmin() method returns indices of the min element of the array in a particular axis. Return : Array of indices into the array with same shape as array.
Detailed explanation-4: -You can use this built-in max() to find the maximum element in a one-dimensional NumPy array, but it has no support for arrays with more dimensions.
