Question

我正在尝试从hi.txt文件中读取数据，hi.txt的内容显示在我上传的图片中。

我要做的是让数据看起来完全像下面的

X = [[0, 0], [0, 1], [1, 0], [1, 1]]
Y = [[0], [1], [1], [0]]

我的代码中包含的内容是

X=[]
Y=[]

和，hi.txt位于c：看起来像

#XOR
#X1 X2 Y
0 0 0
0 1 1
1 0 1
1 1 0

而且，我应该做些什么来通过阅读来创建这样的数据结构 txt数据..？

Answer 1

我认为应该这样做。

[Route("~/")]

Answer 2

使用numpy.loadtxt：

In [30]: arr = np.loadtxt('Desktop/a.txt')

In [31]: X, Y = arr[:,:2], arr[:,2:]

In [32]: X
Out[32]: 
array([[ 0.,  0.],
       [ 0.,  1.],
       [ 1.,  0.],
       [ 1.,  1.]])

In [33]: Y
Out[33]: 
array([[ 0.],
       [ 1.],
       [ 1.],
       [ 0.]])

Answer 3

with open("hi.txt") as f:
    X ,Y = [], []
    for line in f:
        if not line.startswith("#"):
            x1, x2, y1 = line.strip().split()
            X.append([x1, x2])
            Y.append([y1])

Answer 4

X = [[None for x in range(2)] for y in range(4)]
Y = [[None] for y in range(4)]
i=0
with open('hi.txt', 'r') as file:
    for row in file:
        if row[0]!="#":
            a, b, c = row.split()
            print ("\nReading row # %d from file: %s") %(i, row)
            X[i]=[int(a),int(b)]
            Y[i]=[int(c)]
            i+=1
            print "X[] is now:", X
            print "Y[] is now:", Y

print ("\n\nFinal Output:")
print (X)
print (Y)
