파이썬 평균 구하기

1 개요

파이썬 average()

Python 3

nums = [1, 2, 3, 4]
print( sum(nums)/len(nums) )
# 2.5
nums = [1, 2, 3, 4, 5]
print( sum(nums)/len(nums) )
# 3.0

Python 2

nums = [1, 2, 3, 4]
print( sum(nums)/len(nums) )
# 2
nums = [1, 2, 3, 4, 5]
print( sum(nums)/len(nums) )
# 3

nums = [1, 2, 3, 4]
print( 1.0*sum(nums)/len(nums) )
# 2.5
nums = [1, 2, 3, 4, 5]
print( 1.0*sum(nums)/len(nums) )
# 3.0

NumPy

import numpy as np
a = np.array([1,2,3,4])
print( a.mean() )
# 2.5
