在6列python上打印一个数字列表

我在一行中打印了一个或多个这样的列表:0.232 2.34234 ... 1.2232。总共有156个数字。我想在一行中只打印其中的6个:

a b c d e f

g h i j k l

...

到目前为止我已尝试过这个,我的数字在line.dat:

with open('line.dat') as file:
File = file.readlines()
for i in range(len(File)/6+1):
    print ''.join(File[i*6:(i+1)*6]) 

然而,这仍然是在一行中打印数字。请有人帮我这个!感谢。

我可以在同一列中打印前52个数字,依此类推(仍然是6列)。这次我有很多数字,我想在同一列中保留前52个等数字。所以最后我有:

1 53 105 157 209 261

2

...

52 104 156 208 260 312

313 ...... ...... ...... ......

......(另外52个数字等等)

答案 0 :(得分:1)

你需要split空格上的数据,你不能切割字符,因为你会切掉部分数字,取六个字符与取六个数字是不一样的,除非你知道确切的长度然后,您需要使用split:

将每个数字子字符串分隔成单个子元素
with open('line.dat')) as f:
    line = f.read().split()
    print("\n".join([" ".join(line[i:i+6]) for i in xrange(0, len(line)-5, 6)]))

答案 1 :(得分:1)

import itertools as it

with open('data') as f:
    lines = f.readlines()


k = lines[0].split()

i = iter(k)

for j in range(len(k) // 6):
    print(list(it.islice(i, 0, 6)))

如果文件行是范围(156) 的输出
