numpy mean in python code example
Example 1: numpy mean
>> import numpy as np
>> a=[1,2,3,4,5]
>> np.mean(a)
3.0
Example 2: mean of a vector in python
>>> import numpy
>>> numbers = [3, 2, 8, 7]
>>> mean = numpy.mean(numbers)
>>> mean
5.0
Example 3: numpy average
import numpy as np
a = np.arange(6).reshape(3,2)
average = np.average(a)
Example 4: python mean ndarray
# define ndarray a
a = np.array([[1, 2], [3, 4]])
# get the mean
np.mean(a, axis=None)
