In this tutorial, we will discuss methods to get the index of the maximum and minimum value of a list in Python.

max()Get the index of the maximum value in a list using and list.index()functions in Python

max()The function gives the maximum value in a Python list. list.index(x)The method gives xthe index of in a list. The following code example shows us how to get the index of the maximum value of a list using the max()and list.index()functions in Python.

list1 = [10, 12, 13, 0, 14]

tmp = max(list1)
index = list1.index(tmp)

print(index)

Output:

4

In the code above, we first use max()the function to get list1the maximum value in the list and store it in tmp, and then get the index of the maximum value by tmppassing to list1.index()the method. If we only want to display the index of the maximum value, the above code can be shortened.

list1 = [10, 12, 13, 0, 14]

print(list1.index(max(list1)))

Output:

4

min()Get the index of the minimum value in a list using and list.index()functions in Python

min()The function gives the minimum value in a Python list. list.index(x)The method has been discussed in the previous section. The following code example shows us how to get the index of the minimum value of a list using the min()and functions in Python.list.index()

list1 = [10, 12, 13, 0, 14]

tmp = min(list1)
index = list1.index(tmp)

print(index)

Output:

3

In the above code, we first use min()the function to get list1the minimum value within the list and store it in tmp, and then tmppass to list1.index()the function. The above code can be shortened if we only want to display the index of the minimum value.

list1 = [10, 12, 13, 0, 14]

print(list1.index(min(list1)))

Output:

3

numpy.argmax()Get the index of the maximum value of a list using the function in Python

NumPyThe get_maximum_value function from the package numpy.argmax()provides us with the index of the maximum value in a list or array as an argument passed to the function as a parameter. The following code example shows us how to numpy.argmax()get the index of the maximum value of a list using the get_maximum_value function in Python.

import numpy

list1 = [10, 12, 13, 0, 14]
maxindex = numpy.argmax(list1)

print(maxindex)

Output:

4

In the code above, we use numpy.argmax()the function to get list1the index of the maximum value in the list .

Use the function in Python numpy.argmin()to get the index of the minimum value of a list

NumPyThe function in the package numpy.argmin()provides us with a list or array to pass as an argument to the function. The following code example shows us how to numpy.argmin()get the index of the minimum value of a list using the function in Python.

import numpy

list1 = [10, 12, 13, 0, 14]
minindex = numpy.argmin(list1)

print(minindex)

Output:

3

In the code above, we use numpy.argmin()the function to get list1the index of the minimum value in the list .
