我有两个5乘1的垂直阵列
x = [[1]
[2]
[3]
[4]
[5]]
y = [[92]
[93]
[94]
[95]
[96]]
我需要在文本文件中输出(belo)
1 92
2 93
3 94
4 95
5 96
我的脚本看起来像这样
x= numpy.vstack((z))
y= numpy.vstack((r))
numpy.savetxt('fin_lower.dat', ??, fmt='%.4e')
感谢任何帮助

制作2个数组:
In [117]: x=np.arange(1,6).reshape(-1,1)
In [119]: y=np.arange(92,97).reshape(-1,1)
因为它们是2d,concatenate
效果很好; hstack
和column_stack
。
In [122]: xy=np.concatenate((x,y),axis=1)
In [123]: xy
Out[123]:
array([[ 1, 92],
[ 2, 93],
[ 3, 94],
[ 4, 95],
[ 5, 96]])
In [124]: xy=np.hstack((x,y))
现在我有一个2d数组(5行,2列),可以以所需的格式保存:
In [126]: np.savetxt('test.txt',xy)
In [127]: cat test.txt
1.000000000000000000e+00 9.200000000000000000e+01
2.000000000000000000e+00 9.300000000000000000e+01
3.000000000000000000e+00 9.400000000000000000e+01
4.000000000000000000e+00 9.500000000000000000e+01
5.000000000000000000e+00 9.600000000000000000e+01
In [128]: np.savetxt('test.txt',xy, fmt='%.4e')
In [129]: cat test.txt
1.0000e+00 9.2000e+01
2.0000e+00 9.3000e+01
3.0000e+00 9.4000e+01
4.0000e+00 9.5000e+01
5.0000e+00 9.6000e+01
In [131]: np.savetxt('test.txt',xy, fmt='%d')
In [132]: cat test.txt
1 92
2 93
3 94
4 95
5 96
