Best answer: How do you find the index of the minimum value in an array in Python?

How do you find the minimum index of a Numpy array?

Find index of minimum value :

  1. # Get the indices of minimum element in numpy array.
  2. result = numpy. where(arr == numpy. amin(arr))
  3. print(‘Returned tuple of arrays :’, result)
  4. print(‘List of Indices of minimum element :’, result[0])

How do you find the minimum value in Python?

The Python min() function returns the lowest value in a list of items. min() can be used to find the smallest number in a list or first string that would appear in the list if the list were ordered alphabetically.

How do you find the index of the maximum value in an array in Python?

How to find the index of the max value in a list in Python

  1. number_list = [1, 2, 3]
  2. max_value = max(number_list) Return the max value of the list.
  3. max_index = number_list. index(max_value) Find the index of the max value.
  4. print(max_index)

How do you find the minimum value of an array?

For an array of ascending order the first element is the smallest element, you can get it by arr[0] (0 based indexing). If the array is sorted in descending order then the last element is the smallest element,you can get it by arr[sizeOfArray-1].

What is the way to find the maximum number in the NumPy array?

Find maximum value:

  1. # Get the maximum element from a Numpy array.

  3. print(‘Max element from Numpy Array : ‘, maxElement)

How do I turn a list into a NumPy array?

To convert a Python list to a NumPy array, use either of the following two methods:

  1. The np. array() function that takes an iterable and returns a NumPy array creating a new data structure in memory.
  2. The np. asarray() function that takes an iterable as argument and converts it to the array. The difference to np.

What is Max () in Python?

As the name suggests the Max function in Python is used to return the largest (Maximum) element. Although the value returned is always the largest the methods it uses to arrive at it is based on the arguments passed as a parameter. And depending on the parameter, there are two syntaxes.

What does find () mean in Python?

Definition and Usage

The find() method finds the first occurrence of the specified value. The find() method returns -1 if the value is not found. The find() method is almost the same as the index() method, the only difference is that the index() method raises an exception if the value is not found. (

How do you find the minimum and maximum value in Python?

Use max() and min() to find the maximum and minimum of a list

  1. a_list = [5, 2, 7, 6, 3, 1, 9]
  2. maximum = max(a_list)
  3. print(maximum)
  4. minimum = min(a_list)
  5. print(minimum)

What is a Numpy array?

A numpy array is a grid of values, all of the same type, and is indexed by a tuple of nonnegative integers. The number of dimensions is the rank of the array; the shape of an array is a tuple of integers giving the size of the array along each dimension.

How do you find the second highest value in Python?

Approach to find second largest number in a list
