Hello.
In here http://mail.python.org/pipermail/tutor/2001-February/003385.html
You had written how to ger root in python. The way is: "from math import
sqrtprint sqrt( 49 )".
I noticed that if I write just "print sqrt(49)" I get nothing. So why I need to write "from
math import sqrt" instead of write just "print sqrt( 49 )"?
P.S. Sorry about english-I'm lithuanian. :)
