在Python中从文本文件形成元组/列表

Question

I have file of format:

C1  A1
C2  A2
C3  A3  
C1  A4
C4  A5

Each line is separted by a tab. Can I get this file in array/list/tuple directly so that the columns of each line can be accessible through index? Like [(c1,a1),(c2,a2)..] Any python functions allows us to do this?

Answer 1

This should do :

with open('filename.txt') as file:
  result = [line.split() for line in file]

It outputs :

>>> with open('filename.txt') as file:
...   result = [line.split() for line in file]
... 
>>> result
[['C1', 'A1'], ['C2', 'A2'], ['C3', 'A3'], ['C1', 'A4'], ['C4', 'A5']]
