import and reload problem python

Question

I learned the basics of Python with other resources and then decided to read Mark Lutz's book. At the second task I was asked to import file with simple code by example: 

» from imp import reload 
» reload(script1) 
*some code* 
» 
And yes, I know that there's importlib instead of imp (they didn't change it to 5th edition). I actually tried to write this in different combinations but still nothing. When I do as it probably should be it goes: 

»from importlib import reload 
»reload(script1) 
Traceback (most recent call last): 
File "<pyshell#1>", line 1, in <module> 
reload(script1) 
NameError: name 'script1' is not defined 

I've read that it can have to do something with where the file is saved but I did it with different files even in a folder where Python IDLE and other stuff are downloaded. There's no problem with code itself. 
I most likely don't see the answer under my nose so I would like to ask you to help me

Answer 1

Do you have a script named "script1"

Answer 2

No, script1 definitely exists I even rewrote it and put copies in different folders. And yes, I reloaded IDLE after changing the file.
