python mean function code example

Example 1: how to calculate mean in python

import statistics

a = [1,2,3,4,5]

mean = statistics.mean(a) 
#Similar for other values such as variance, standard deviation

Example 2: python mean

# Probably the most convenient set of statistics functions are found
# in the Numpy package

# Basic syntax:
import numpy as np
np.mean(your_list) # Calculate mean
np.median()	# Calculate median
np.std()	# Calculate standard deviation
np.var()	# Calculate variance

Example 3: mean python code

>>> import statistics

>>> statistics.mean([4, 8, 6, 5, 3, 2, 8, 9, 2, 5])
5.2

Example 4: mean python

import numpy as np
values=[1,10,100]
print(np.mean(values))
values=[1,10,100,np.nan]
print(np.nanmean(values))

Example 5: mean python code

>>> def my_mean(sample):
...     return sum(sample) / len(sample)
...

>>> my_mean([4, 8, 6, 5, 3, 2, 8, 9, 2, 5])
5.2
