Orgmode tables are handy and powerful. I was copying and pasting few column arrays from a spreadsheet application to orgmode, and I wasn't able to concatenate the vectors to an org-table. So, I assigned the vectors to variables in python and I exported them both in orgmode and to a tsv file.
#+NAME: decimal | 10 | | 20 | | 30 | | 40 | | 50 | | 60 | | 70 |
#+NAME: hexadecimal | 0xA | | 0x14 | | 0x1e | | 0x28 | | 0x32 | | 0x3c | | 0x46 |
The code below is a way to join vectors in a 2D org-table. Also is a demonstration to export tsv using python.
#+BEGIN_SRC python :exports both :var decs=decimal hexs=hexadecimal import csv file = open('test', 'w') data =  for i in range(0,7): data.append([decs[i], hexs[i]]) # use TAB delimiter to write tsv file writer = csv.writer(file, delimiter='\t') for item in data: writer.writerow(item) file.close() return data #+END_SRC
#+RESULTS: | 10 | 0xA | | 20 | 0x14 | | 30 | 0x1e | | 40 | 0x28 | | 50 | 0x32 | | 60 | 0x3c | | 70 | 0x46 |
Pandas is a data analysis library in python, with handy functionality.
#+BEGIN_SRC python :exports both import pandas as pd bpm = pd.read_csv('test', sep='\t', header=None, names=['Dec', 'Hex']) return bpm.tail() #+END_SRC
Now, notice that the leftmost column is an enumeration produced by pandas.
#+RESULTS: : Dec Hex : 2 30 0x1e : 3 40 0x28 : 4 50 0x32 : 5 60 0x3c : 6 70 0x46
