infy.head() and infy.tail() show he right table, with columns, but when I run the next part, I get the following error:



infy_close = infy [['Date','close']]

infy_close.set_index('Date', inplace=True)

infy_close

You can try slicing using loc property.



Try this:



infy_close = infy.loc[:,['Date','close']] 

infy_close.set_index('Date', inplace=True) 

infy_close
