.log()

The .log() function returns an element-wise natural logarithm of an array.

numpy.log(array)

.log() returns an ndarray with each element as the natural logarithm of the corresponding element in array.

The following example creates a ndarray and applies .log() to it:

import numpy as np

nd = np.array([[1,2.71828],[2.71828,1]])

print(nd)
print(np.log(nd))

This produces the following output:

[[1.      2.71828]
 [2.71828 1.     ]]

 [[0.         0.99999933]
 [0.99999933 0.        ]]
