如何将 3d 数组写入文本文件

Question

我有这样的数组：

[[-3.75536609e+00  9.41899478e-01  1.59805989e+00 -8.97728577e-02

  -3.67324662e+00  2.85971731e-01]

 [-1.48593640e+00  6.56555116e-01  6.41966641e-01 -2.62360811e-01

  -4.66498184e+00 -8.62938017e-02]

 [ 7.05197873e-03 -4.12116805e-03 -1.30933505e-02  5.76611329e-03

  -6.51661423e-04 -9.73143987e-03]

 ...

 [ 7.28487849e-01 -2.02445209e-01 -1.56245055e-02 -1.48709917e+00

  -4.94436502e+00 -1.88474905e+00]

 [ 6.85976565e-01 -1.20424531e-01 -2.20480785e-01 -1.23380101e+00

  -3.60452390e+00 -1.54651344e+00]

 [ 1.47314686e-02  1.42228836e-02 -1.20135369e-02 -4.32784623e-03

  -8.07471294e-03  2.29109559e-04]]

[-0.6025902  -0.31237862 -1.2150506   3.072987   -1.3560013  -1.0883616 ]

我希望能够将此数组写入文本文件。每个元素都应逐行打印。例如，第一个看起来像这样

-3.75536609e+00 

 9.41899478e-01 

 1.59805989e+00 

-8.97728577e-02

 -3.67324662e+00 

 2.85971731e-01

我该怎么做呢？

Answer 1

如果这些是numpy数组，您可以使用np.savetxtwith delimiter='\n'，并枚举您的数组：给定数组x：>>> xarray([[-3.75536609e+00,  9.41899478e-01,  1.59805989e+00,        -8.97728577e-02, -3.67324662e+00,  2.85971731e-01],       [-1.48593640e+00,  6.56555116e-01,  6.41966641e-01,        -2.62360811e-01, -4.66498184e+00, -8.62938017e-02],       [ 7.05197873e-03, -4.12116805e-03, -1.30933505e-02,         5.76611329e-03, -6.51661423e-04, -9.73143987e-03]])用：[np.savetxt(f'array{n}.txt',i,delimiter='\n') for n,i in enumerate(x)]你会得到 3 个文本文件：array0.txt 将：-3.755366089999999879e+009.418994779999999567e-011.598059890000000038e+00-8.977285769999999998e-02-3.673246620000000018e+002.859717310000000068e-01等等...[编辑]看来我误解了你的问题。如果您只想要一个 txt 文件，请使用：np.savetxt('array.txt', x.flatten(), delimiter='\n')这将给出array.txt：-3.755366089999999879e+009.418994779999999567e-011.598059890000000038e+00-8.977285769999999998e-02-3.673246620000000018e+002.859717310000000068e-01-1.485936399999999935e+006.565551160000000497e-016.419666410000000045e-01-2.623608110000000271e-01-4.664981840000000268e+00-8.629380170000000572e-027.051978730000000098e-03-4.121168050000000374e-03-1.309335049999999986e-025.766113290000000370e-03-6.516614230000000382e-04-9.731439870000000575e-03
