Python - 讀取txt檔案並存成1D array 或 2D array

==============================
'''
'1.txt' => A,B,C
'2.txt' => 1,2,3
'3.txt' => 6,7,8
'''

import os
import numpy as np

Dirlist = []
CC = []

EE = np.empty((0,3))                                                     

Dirlist = os.listdir("C:\\Users\\Ricky\\Desktop\\Test")                                                              # 這個目錄下的資料

print("Dirlist=",Dirlist)

for i in range (len(Dirlist)):
    with open("C:\\Users\\Lightel-Ricky\\Desktop\\Test\\"+Dirlist[i],"r") as f   :                      # 一個一個打開資料
      # newList = f.read().split(",")                                                                                              # String用","分割成 list
      # newList = DD.split(",")
      newList = f.read().split(",") 
      CC = np.concatenate((CC ,newList),axis=0)                                                                     # 一個一個打開資料後存到Array裡面
      EE = np.vstack([EE,newList])
print ("CC=",CC)
print ("EE=",EE)
