打印不带括号的Numpy数组 [英] Printing Numpy arrays without brackets

问题描述

predictions  = [x6,x5,x4,x3,x2,x1]
predictions

调用上面的列表将产生以下数组:

Calling the above list yields the following arrays:

[array([782.36739152]),
 array([783.31415872]),
 array([726.90474426]),
 array([772.08910103]),
 array([728.79734162]),
 array([753.67887657])]

但是我只想打印或调用内部的数字，数字周围没有数组或方括号.

Yet I would like to print or call just the numbers inside, no array or brackets around the numbers.

使用下面的函数可以将数字干净地保存为CSV，但是我不想保存数字，我想在iPython中调用它们:

Using the function below cleanly saves just the numbers to CSV, but I DON'T want to save the numbers, I want to call them inside iPython:

np.savetxt("P:/Earnest/Old/R/OutputPython.csv", predictions, delimiter=",")

我该如何实现?

推荐答案

如果将predictions更改为numpy数组，则可以使用print(*predictions.flatten(), sep=', ').

If you change predictions to numpy array then, you can use print(*predictions.flatten(), sep=', ').

您可以尝试以下操作:

import numpy as np

predictions = np.array([np.array([782.36739152]),
                        np.array([783.31415872]),
                        np.array([726.90474426]),
                        np.array([772.08910103]),
                        np.array([728.79734162]),
                        np.array([753.67887657])])


print(*predictions.flatten(), sep=', ')

输出:

782.36739152, 783.31415872, 726.90474426, 772.08910103, 728.79734162, 753.67887657
