실수 넘파이 배열을 소수점 자리 맞추어 공백없이 쉼표구분으로 출력하기

numpy 배열의 데이터를 원본 csv 파일에서 찾을 목적으로 만들었던 코드였는데 간단한 데이터로 예제코드를 만들어봤습니다.

import numpy as np 


a = np.linspace(0.01, 1.00, 9).reshape(3, 3)

print('original')
print(a)
print()

print('new')
np.set_printoptions(suppress=True)
print('\n'.join(','.join(str(format(cell,"0.3f")) for cell in row) for row in a))

 

original [[0.01    0.13375 0.2575 ]  [0.38125 0.505   0.62875]  [0.7525  0.87625 1.     ]] new 0.010,0.134,0.258 0.381,0.505,0.629 0.752,0.876,1.000
