在python上读取txt文件的列 [英] Reading columns of a txt file on python

问题描述

我正在处理一个 .txt 文件.这有 100 行和 5 列.我需要将它分成五个长度为 100 的向量，每列一个.我正在尝试遵循:从文本文件中读取特定列在python中.

I am working with a .txt file. This has 100 rows and 5 columns. I need to divide it in five vectors of lenght 100, one for each column. I am trying to follow this: Reading specific columns from a text file in python.

但是，当我将其实现为:

However, when I implement it as:

token = open('token_data.txt','r')
linestoken=token.readlines()
resulttoken=[]
for x in linestoken:
    resulttoken.append(x.split(' ')[1])
token.close()

我不知道这是如何存储的.如果我写 print('resulttoken')，屏幕上不会出现任何内容.

I don't know how this is stored. If I write print('resulttoken'), nothing appears on my screen.

谁能告诉我我做错了什么?

Can someone please tell me what I am doing wrong?

谢谢.我的文本文件的一部分

推荐答案

x.split(' ') 没有用，因为文本文件的列被多个空格分隔.使用 x.split() 忽略空格:

x.split(' ') is not useful, because columns of your text file separated by more than one space. Use x.split() to ignore spaces:

token = open('token_data.txt','r')
linestoken=token.readlines()
tokens_column_number = 1
resulttoken=[]
for x in linestoken:
    resulttoken.append(x.split()[tokens_column_number])
token.close()
print(resulttoken)
