Python Finding the average of a list Stack Overflow
Instead of installing the whole numpy package for just avg mean if using python 3 we can get this thing done using statistic module just by from statistic import mean or if on python 2 7 or less the statistic module can be downloaded from src hg python cpython file default Lib statistics py doc docs python dev library statistics htm

NumPy mean Mean of Array Python Examples
1 Mean of a numpy array In this example we take a 2D NumPy Array and compute the mean of the Array Python Program import numpy as np Initialize array A np array 2 1 5 4 Compute mean output np mean A print output Run Code Copy Output 3 0 Mean Mean 2 1 5 4 4 12 4 3 0 2 Mean of numpy array along an axis
NumPy mean Calculate the Average of Elements in an Array, How it works First create an array that has three numbers a np array 1 2 3 Code language Python python Second calculate the average of elements in the array a using the mean function average np mean a Code language Python python Third display the average print average Code language Python python

Code 1 import numpy as np arr 20 2 7 1 34 print arr arr print mean of arr np mean arr Output arr 20 2 7 1 34 mean of arr 12 8 Code 2 import numpy as np arr 14 17 12 33 44 15 6 27 8 19 23 2 54 1 4 print nmean of arr axis None np mean arr Numpy mean in Python GeeksforGeeks. Mean of entire array 3 5 Mean of only even elements 4 0 Mean of numbers greater than 3 5 0 Example 5 Use out to Store the Result in Desired Location The out parameter allows to specify an output array where the result will be stored When you run that code you ll find that the values are being stored as integers int64 to be precise Now let s use numpy mean to calculate the mean of the numbers mean output np mean np array 1d int Now we can check the data type of the output mean output
