I entered:

e, s, t= var('e s t')

and Sage returned

File " " , Line 1, in <module>

what does it mean and how can I correct it?

I can not reproduce your problem, perhaps did you type a special character instead of a space somewhere. Try to retype everything, and do not put any space before your command.

What operating system? What version of Sage? How was it installed? How are you using it: terminal, Jupyter notebook, other? What is the complete error message?

thank you @slelievre and @tmonteil . I use it in Oracle VM VirtualBox. I wanted to paste the codes and the errors here but it could not be pasted and I do not know why!!!!!!!! Do you know how it works? Is there another way of "copping and pasting"?

Maybe try a screenshot instead. Please also answer the other questions of @slelievre, so that you can be helped.

This looks like the error that appears when calling "var" inside python, not inside sage..

As Frédéric suggests, you need to run Sage and not Python. If you are using the terminal, run sage; if you are using the SageNB notebook, select Sage mode.
