在python中读取时，将文本的所有值转换为int

Question

当我试图将值转换为int时，我在python中遇到了这个错误。你知道吗

invalid literal for int() with base 10: '0,72367,72565,73005,73087,73113,73129,73313,73661,74049,74222,74350,74403,74501\n'

我要的不是这个

0,72367,72565,73005,73087,73113,73129,73313,73661,74049,74222,74350,74403,74501

存储在int的numpy数组中

我的密码是

f = open('points.txt')
# reading the lines of the file
line = f.readline()
while line:
    points = np.array([], dtype=int)
    #print("voxel", voxel_label, " : ", line)
    points = np.append(points, line)
    line = f.readline()
    voxel_label += 1

当我把点转换成int时，它给了我一个错误。我想从文本文件中读取行，并将其作为int值放入numpy数组点中。你知道吗

points    array(['0,1883,1965,2176,2236,2273,2502,2528,2542,2963,2979,3288,3519\n'],
          dtype='<U62')

我想把这个'points'numpy数组转换成int类型。我不明白为什么结尾有。你知道吗

如何将“points”numpy转换为int

Answer 1

如果您的文件纯粹由逗号分隔的数字组成，则需要以下内容：

numbers = []
with open('points.txt', 'r') as f:
    for line in f:
        numbers.extend([int(num)
                       for num in line.split(',')])

# ... do whatever with the numbers list
