[Tutor] about import statement

[arun kumar]

Hi Friends,

I'm Arun Kumar from India, Just a month ago i started learning
programming .learned some basics of python. I'm really enjoying
programming in python.

I have some doubts in python. When we write programs,we write some
import statements at the beginning of the code. how to know that we
should import something. How do we know that certain classes are in
particular module?

Thanks

Arun Kumar
