파이썬 평균 구하기
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

2 NumPy

NumPy mean() 문서를 참고하십시오.

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