Question

我有以下文件salida.txt，在此示例中列数不同，只有2个。

cil HUF, M1 NSS,
442, 1123,
20140130, 2014012,
20140131, 2014014,

我想读取文件并将每列添加到新数组中。我不想这样：

['cli HUF', '442', '20140130', '20140131']
[' M1 NSS', '1123', '2014012', '2014014']

到目前为止我尝试过：

file = open('salida.txt', 'r')
for line in file:
    // add them to the arrays

我遇到了处理数组数量的问题（它不总是2，取决于文件的列数），并从行中取出每个单词以添加到正确的数组中。如果我放入de loop print line[0]，它会打印整行，我想逐字处理。

Answer 1

删除最后一个逗号，然后在中心逗号中分割该行：

list1, list2 = [], []
file = open('salida.txt', 'r')
for line in file:
    w1, w2 = line.strip(',').split(', ')
    list1.append(w1)
    list2.append(w2)

Answer 2

你去了：

file = open('salida.txt', 'r')
lines = file.readlines()
file.close()
arrays = []
words = lines[0].split(",")
for i in range(0,len(words)):
    arrays.append([words[i]])
for i in range(1,len(lines)):
    words = lines[i].split(",")
    for j in range(0,len(words)):
        arrays[j].append(words[j])

Answer 3

arrays = []
with open('salida.txt', 'r') as wordfile:
    for line in wordfile:
        # Split the line on commas.
        words = line.split(',')
        for count, word in enumerate(words):
            # Remove any whitespace.
            word = word.strip()
            # That might leave a blank string, e.g. at the end.
            if word:
                # Do we need to add another array to our list of arrays?
                if count == len(arrays):
                    arrays.append([])
                arrays[count].append(word)
print arrays

Answer 4

import csv

with open('salida.txt') as f:
    whatYouWant = zip(*list(csv.reader(f)))[:-1]

读取文件并使用每列的单词创建数组
