如何将多个 python 数据帧转储/写入一个文本文件并保留它们的标题行？

Question

I have multiple pandas dataframes each with a different shape. Some dataframes have 2 lines of header lines, some have only 1 header line. Each a different number of columns.

How to dump/write multiple python dataframes to a text file keeping their header lines?

Answer 1

I just tried this and it worked :

df1.to_csv(r"C:\Users\sb512911\Desktop\All\Applications\VDR\output\out.txt", sep = ' ', mode = 'a')

df2.to_csv(r"C:\Users\sb512911\Desktop\All\Applications\VDR\output\out.txt", sep = ' ', mode = 'a')

Please see if this works for you as well.

Answer 2

Thanks, I did in the old manner. Without thinking in dataframes, I read file and write line by line.
