[Python] Numpy 행별 열별 max, min, sum, mean 구하는 방법

#1 행별, 열별 합

#2 행별, 열별 최대값

#3 행별, 열별 최소값

#4 행별, 열별 평균

 

#1 행별, 열별 합

import numpy as np

temp_list = [[1,3,5,7,9], [2,4,6,8,10]]
temp_np_array = np.array(temp_list)

print(temp_np_array, temp_np_array.shape)
print(temp_np_array.sum(axis=1))
print(temp_np_array.sum(axis=0))

 

#2 행별, 열별 최대값

import numpy as np

temp_list = [[1,3,5,7,9], [2,4,6,8,10]]
temp_np_array = np.array(temp_list)

print(temp_np_array, temp_np_array.shape)
print(temp_np_array.max(axis=1))
print(temp_np_array.max(axis=0))

 

#3 행별, 열별 최소값

import numpy as np

temp_list = [[1,3,5,7,9], [2,4,6,8,10]]
temp_np_array = np.array(temp_list)

print(temp_np_array, temp_np_array.shape)
print(temp_np_array.min(axis=1))
print(temp_np_array.min(axis=0))

 

#4 행별, 열별 평균

import numpy as np

temp_list = [[1,3,5,7,9], [2,4,6,8,10]]
temp_np_array = np.array(temp_list)

print(temp_np_array, temp_np_array.shape)
print(temp_np_array.mean(axis=1))
print(temp_np_array.mean(axis=0))
