Pandas Series to Excel
提问by ojdo
The pandas.Series object does have many to_*functions, yet it lacks a to_excelfunction. Is there an easier/better way to accomplish the export in line 3 of this snippet? It feels clunky to first convert the Series to a DataFrame simply for a simple I/O:
pandas.Series 对象确实有很多to_*功能,但它缺少一个to_excel功能。是否有更简单/更好的方法来完成此代码段第 3 行中的导出?首先将 Series 转换为 DataFrame 只是为了一个简单的 I/O,感觉很笨拙:
import numpy as np
import pandas as pd
s = pd.Series([1,3,5,np.nan,6,8])
pd.DataFrame(s).to_excel('s.xlsx', 's')
回答by Phillip Cloud
You can either:
您可以:
1. construct a DataFramefrom the start,
1.DataFrame从一开始就构造一个,
in which case you've already answered your own question.
在这种情况下,您已经回答了自己的问题。
2. Use Series.to_frame()
2. 使用 Series.to_frame()
s.to_frame(name='column_name').to_excel('xlfile.xlsx', sheet_name='s')

New in 0.20: Series.to_excel()
0.20 中的新功能:Series.to_excel()
Beginning with pandas version 0.20, Series now supports to_exceldirectly (see PR #8825for details):
从 pandas 0.20 版本开始,Series 现在to_excel直接支持(详见PR #8825):
import pandas as pd
s = pd.Series([0, 1, 2, 4, 8, 16], name='a_series')
s.to_excel('foo.xlsx')
Contents of file foo.xlsx:
文件 foo.xlsx 的内容:
