get index of max value 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: index to min python

import numpy as np
index_min = np.argmin(values)

Example 3: find location of max value in python list

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

Example 4: how to get index of max n values in an array

In [1]: import numpy as np

In [2]: arr = np.array([1, 3, 2, 4, 5])

In [3]: arr.argsort()[-3:][::-1]
Out[3]: array([4, 3, 1])
