如何使用python将3D数组导出到excel中的单行

Question

I am attempting to export a large array of 3D points into excel.

import numpy as np
import pandas as pd

d = np.asarray(data)
df = pd.Dataframe(d)
df.to_csv("C:/Users/Fred/Desktop/test.csv")

This exports the data into rows as below:

3.361490011 -27.39559937 -2.934410095
4.573401244 -26.45699201 -3.845634521

.....

Each line representing the x,y,z coordinates. However, for my analysis, I would like that the 2nd row is moved to columns beside the 1st row, and so on, so that all the coordinates for one shape are on the one row of the excel. I tried turning the data into a string but this returned the above too.

The reason is so I can add some population characteristics to the row for each 3d shape. Thanks for any help that anyone can give.

Answer 1

您可以使用x = df.to_numpy().flatten()来展平数据，然后使用np.savetxt将其保存到 csv 中。
