如何将两个列表中的数据写入csv中的列？

I want to write data that I have to create a histogram into a csv file. I have my 'bins' list and I have my 'frequencies' list. Can someone give me some help to write them into a csv in their respective columns?

我想写一些数据，我必须在csv文件中创建一个直方图。我有我的'箱'列表，我有'频率'列表。有人可以给我一些帮助，将它们写入各自列中的csv吗？

ie bins in the first column and frequency in the second column

即第一列中的箱和第二列中的频率

This example uses izip (instead of zip) to avoid creating a new list and having to keep it in the memory. It also makes use of Python's built in csv module, which ensures proper escaping. As an added bonus it also avoids using any loops, so the code is short and concise.

此示例使用izip（而不是zip）来避免创建新列表并将其保留在内存中。它还使用了Python内置的csv模块，可以确保正确的转义。作为额外的奖励，它还避免使用任何循环，因此代码简洁明了。

import csv
from itertools import izip

with open('some.csv', 'wb') as f:
    writer = csv.writer(f)
    writer.writerows(izip(bins, frequencies))

Note that in Python 3.0 and later, you don't need izip anymore—the builtin zip now does what izip used to do.

请注意，在Python 3.0及更高版本中，您不再需要izip - 内置zip现在可以执行izip以前的操作。
