Python：在csv中为许多行写两列

Question

我有两个参数，例如filename和time，我想将它们写在csv文件的列中。这两个参数位于for-loop中，因此它们的值在每次迭代中都会更改。

我当前的python代码是下面的代码，但生成的csv不是我想要的：

import csv
import os
with open("txt/scalable_decoding_time.csv", "wb") as csv_file:   
    writer = csv.writer(csv_file, delimiter=',')
    filename = ["one","two", "three"]
    time = ["1","2", "3"]
    zipped_lists = zip(filename,time)
    for row in zipped_lists:
        print row
        writer.writerow(row)

我的csv文件必须如下所示。 ,必须是分隔符。所以我必须得到两列。

one,   1
two,   2
three, 3

我的csv文件现在如下图所示。数据存储在一列中。

你知道如何解决这个问题吗？

Answer 1

嗯，这里的问题是，您使用的是writerows而不是writerow

import csv
import os
with open("scalable_decoding_time.csv", "wb") as csv_file:   
    writer = csv.writer(csv_file, delimiter=',')
    level_counter = 0
    max_levels = 3
    filename = ["one","two", "three"]
    time = ["1","2", "3"]
    while level_counter < max_levels:
        writer.writerow((filename[level_counter], time[level_counter])) 
        level_counter = level_counter +1 

这给了我结果：

one,1
two,2
three,3

输出：

Answer 2

这是另一种解决方案

将以下代码放入我们将调用sc-123.py

的python脚本中

filename = ["one","two", "three"]
time = ["1","2", "3"]

for a,b in zip(filename,time):
    print('{}{}{}'.format(a,',',b))

一旦脚本准备就绪，就像那样运行

python2 sc-123.py > scalable_decoding_time.csv

您将按照您希望的方式格式化结果

one,1
two,2
three,3
