python添加空行_python – 使用pandas在数据框中追加一个空行

我试图在数据帧的末尾附加一个空行,但无法这样做,甚至试图理解pandas如何使用追加功能而仍然没有得到它.

这是代码：

import pandas as pd

excel_names = ["ARMANI+EMPORIO+AR0143-book.xlsx"]

excels = [pd.ExcelFile(name) for name in excel_names]

frames = [x.parse(x.sheet_names[0], header=None,index_col=None).dropna(how='all') for x in excels]

for f in frames:

f.append(0, float('NaN'))

f.append(2, float('NaN'))

有两列和随机数的行.

在for循环中使用“print f”获取：

0 1
