将数据帧写入csv

Question

我正在尝试使用!cat将数据帧写入csv文件，但我遇到了一些错误。

代码：

data.to_csv(r'C:\Users\Downloads\pydata\pydata-book-2nd-edition\examples\out.csv')
!cat C:\Users\Pruthvish\Downloads\pydata\pydata-book-2nd-edition\examples\out.csv
,something,a,b,c,d,message
0,one,1,2,3.0,4
1,two,5,6,,8,world
2,three,9,10,11.0,12,foo

错误：

'cat' is not recognized as an internal or external command, operable program or batch file.

      4 1,two,5,6,,8,world
      5 2,three,9,10,11.0,12,foo

NameError: name 'something' is not defined

我甚至尝试了!type和!more，但名称错误仍然存​​在。我该如何解决这个错误？
