Renaming series in pandas
提问by user1867185
I am working with series, and I was wondering how I can rename the series when writing to a file. For example, my output csv consists of the following:
我正在使用系列，我想知道如何在写入文件时重命名系列。例如，我的输出 csv 包含以下内容：
Gene_Name,0
A2ML1,15
AAK1,8
I want it to be the following:
我希望它如下：
Gene_Name,Count
A2ML1,15
AAK1,8
Note: I don't want my header to be "Gene_Name,0" but "Gene_Name,Count." How can I accomplish this?
注意：我不希望我的标题是“Gene_Name,0”而是“Gene_Name,Count”。我怎样才能做到这一点？

To make "Count" the name of your series, just set it with your_series.name = "Count"and then call to_csv like this: your_series.to_csv("c:\\output.csv", header=True, index_label="Gene_Name").
要将“计数”作为您系列的名称，只需将其设置为your_series.name = "Count"，然后像这样调用 to_csv：your_series.to_csv("c:\\output.csv", header=True, index_label="Gene_Name")。

Another way to do it:
另一种方法：
s.to_frame("Count").to_csv("output.csv", header=True, index_label="Gene_Name")
or
或者
s.reset_index(name="Count").to_csv("output.csv", header=True, index_label="Gene_Name")
