编写两个列表以分隔 csv 列

Question

我正在尝试将 json 解析为 csv，分成单独的列，但它不断合并为一个。

人们在下面提出了几种解决方案，但无济于事。我在代码下方发布了我正在使用的数据。

它一直说我需要添加更多细节，但就是这样。只需要一些帮助来弄清楚如何将 json 写入 csv 中的两列...

喂？谁能帮帮我？

replies_final,original_final = [],[]

  for i in data['items']:
    original = i['snippet']['topLevelComment']['snippet']['textOriginal']
    original_final.append(original)
    if 'replies' in i: 
      x = i['replies']['comments'][0]['snippet']['textOriginal']
      replies_final.append(x)
 

    with open('test.csv',"a+", newline='',encoding="utf-8") as csv_file:
        writer = csv.writer(csv_file)
        for item in original_final,replies_final:
            writer.writerows([item])
            writer.writerows([item])

 csv_file.close()

Answer 1

试试这个：

with open('test.csv', "a+", newline='', encoding="utf-8") as csv_file:
    writer = csv.writer(csv_file)
    writer.writerows(zip(original_final,replies_final))

Answer 2

您需要考虑各种事项，例如，如果您的项目包含多个回复，您可以将它们全部存储到一个临时数组中，如果它不包含任何回复，您可以稍后将其附加到您的 replies_final 对象将保持为空，即使为空，您仍然可以使用与每个项目的 1:1 关系填充您的 replies_final 数组

  for i in data['items']:
    original = i['snippet']['topLevelComment']['snippet']['textOriginal']
    original_final.append(original)
    item_replies = []
    if 'replies' in i: 
        # Here you can iterate over the replies and add them to a temp array
        for reply in i['replies']:
            x = i['replies']['comments'][0]['snippet']['textOriginal']
            item_replies.append(x)
    replies_final.append(item_replies)

然后您可以使用 zip 函数获取两个数组并将它们转换为可以迭代的单个对象，这很好，因为您已经知道对于每个项目，您已经拥有一个 cmets 列表，即使它是空的信息现在将混合。然后你调用了错误的函数而不是使用writerows() 你必须使用writerow() 一次插入一个

with open('test.csv',"a+", newline='',encoding="utf-8") as csv_file:
    writer = csv.writer(csv_file)
    for i in zip(arr,arr2):
        (item, replies) = i
        writer.writerow([item, replies]))

 csv_file.close(
```

Answer 3

我对 csv.writer() 对象如何工作的实验是这样的

writer.writerow([['a', 'b', 'c'], ['d', 'e', 'f']]) 生成 CSV 文件：

a, b, c
d, e, f

当您有 for item in original_final, replies_final 时，在第一次迭代中，items 是一个等于 original_final 的列表，而在第二次迭代中，它是 replies_final，因此它会生成一个包含 original_final 的列，然后是 replies_final

你想要的是第一次迭代，item 有两个元素：

[original_final[0], replies_final[0]]

在第二次迭代中，它应该是 [original_final[1], replies_final[1]]

等等

为此，您可以使用zip 函数，如下所示

for item in zip(original_final, replies_final):

现在，您的下一个问题是 original_final 和 replies_final 必须具有相同的长度，否则 zip 函数将根据两者中最短的一个来裁剪结果

所以你可以做的就是像这样修改你的if 语句

if 'replies' in i: 
  x = i['replies']['comments'][0]['snippet']['textOriginal']
  replies_final.append(x)
else:
  replies_final.append('')

我觉得应该可以

此外，使用with 语句，您无需执行csv_file.close()。你可以把它拿出来

这是最后的代码块

replies_final,original_final = [],[]

for i in data['items']:
    original = i['snippet']['topLevelComment']['snippet']['textOriginal']
    original_final.append(original)
    if 'replies' in i: 
       x = i['replies']['comments'][0]['snippet']['textOriginal']
       replies_final.append(x)
    else:
       replies_final.append('')


    with open('test.csv',"a+", newline='',encoding="utf-8") as csv_file:
        writer = csv.writer(csv_file)
        for item in zip(original_final,replies_final):
            writer.writerows([item])

如果这不起作用，请告诉我

编辑：既然它不适合你，这个最小的例子给你什么？

import csv

f=open('test.csv', 'a+', newline='', encoding='utf-8')

la=['a', 'b', 'c', 'd']
lb=['A', 'B', 'C', 'D']

writer=csv.writer(f)

for item in zip(la, lb):
    writer.writerows([item])

f.close()
