pandas 系列的名称参数是什么? [英] What is the name parameter in Pandas Series?

问题描述

在系列的文档中，不解释name和fastpath的参数.他们是做什么的?

In the doc of Series, the use parameter of name and fastpath is not explained. What do they do?

推荐答案

name参数允许您为Series对象(即列)命名.这样，当您将其放入DataFrame时，该列将根据name参数来命名.

The name argument allows you to give a name to a Series object, i.e. to the column. So that when you'll put that in a DataFrame, the column will be named according to the name parameter.

示例:

In [1]: s = pd.Series(["A","B","C"], name="foo")

In [2]: s
Out[2]: 
0    A
1    B
2    C
Name: foo, dtype: object

In [3]: pd.DataFrame(s)
Out[4]: 
  foo
0   A
1   B
2   C

如果不给Series提供name，它将自动命名.这是dataframe对象中的0:

If you don't give a name to your Series it will be named automatically. Here it will be a 0 in the dataframe object:

   0
0  A
1  B
2  C

对于fastpath，它是一个内部参数，并且已经报告了一个问题:

For the fastpath, it's an internal parameter and an issue has already been reported :
