如何在Python

Question

a= [1,2,3,4,5]
df=DataFrame(a)

.... #setup excelwriter和dataframe

df.to_excel(writer, sheet_name=sheetname,startrow=1, startcol=1, header=False, index=False)

输出：

1\n
2\n
3\n
4\n
5

如何获得输出：

1    2    3    4    5

Answer 1

您可以先转置，然后保存到Excel：

df

   0
0  1
1  2
2  3
3  4
4  5

df.T.to_excel(writer, 
              sheet_name=sheetname,
              startrow=1, 
              startcol=1, 
              header=False, 
              index=False)

1   2   3   4   5

Answer 2

在数据框上使用transpose（）将列转换为行。

import pandas as pd

a= [1,2,3,4,5]
df=pd.DataFrame(a)
df = df.transpose()

print(df)

结果：

   0  1  2  3  4
0  1  2  3  4  5

Answer 3

要在一行中输出，请使用：

df = df.transpose()

完整代码：

#!/usr/bin/python
import pandas as pd 
import xlsxwriter as xlsw

a = [1,2,3,4,5]
df = pd.DataFrame(a)
df = df.transpose()
xlsfile = 'pandas_simple.xlsx'
writer = pd.ExcelWriter(xlsfile, engine='xlsxwriter')

df.to_excel(writer, sheet_name="Sheet1Name",startrow=1, startcol=1, header=False, index=False)
