Calculating arithmetic mean one type of average in Python

Question

Is there a built-in or standard library method in Python to calculate the arithmetic mean (one type of average) of a list of numbers?

Answer 1

There are ways to calculate mean in Python
For Example:

cal_mean = [2,3,4,5,6,7]
print(sum(cal_mean)/ len(cal_mean))

Output

4.5

Another way to calculate mean in Python is by using Numpy 

import numpy as np
cal_mean = [2,3,4,5,6,7]
np.mean(cal_mean)

Output

4.5
