Python_EX-003. how to extract a condition dataset

import numpy as np

# INPUT : SCORE

ClassA = [10, 50, 70, 30]

ClassB = [30, 40, 50, 60]

ClassC = [76, 78, 92, 30]

ClassD = [32, 45, 64, 42]

A = np.array(ClassA).reshape(1,4)

B = np.array(ClassB).reshape(1,4)

C = np.array(ClassC).reshape(1,4)

D = np.array(ClassD).reshape(1,4)

Score = np.concatenate( (A, B, C, D), axis=0)

print("""Score :

""", Score)

#path = ''

#data = np.loadtxt(path, delimiter=',')

cond = Score[:,0] > 55

out = Score[cond, :]     #Extract Data that can meet the given condition

print("""

First Score > 55:

""", out)

 

RESULT

Score :
 [[10 50 70 30]
 [30 40 50 60]
 [76 78 92 30]
 [32 45 64 42]]

First Score > 55:
 [[76 78 92 30]]
