return index of max value python code example

Example 1: python index of max value in list

# any list
a = [1, 7, 3, 12, 5]

# index of minimum element
# if more than 1 minimum, 
# first index is returned
min_index = a.index(min(a))

# index of maximum element
max_index = a.index(max(a))

Example 2: python how to return max num index

import numpy as np

x=[1,2,3,4,5]

max_index=np.argmax(x) 
# return the index of the maximun element
# max_index has the value 4

Example 3: max of list with index

a.index(max(a))

Example 4: find location of max value in python list

>>> m = max(a)
>>> [i for i, j in enumerate(a) if j == m]
[9, 12]

Example 5: index of maximum value in list python

[i for i, x in enumerate(l) if x == max(l)]
