I'm trying to get the code for IF ELSE to work... and it's fine till 'else' appears and then it gives me an error-

for each_item in movies:
	if isinstance (each_item, list):
		for nested_item in each_item:

SyntaxError: invalid syntax

Any idea why this is happening?

Consequently, I also tried playing with
in the python / IDLE shell and it gave me the following error-

Traceback (most recent call last):
File "<pyshell#97>", line 1, in <module>
NameError: name '_builtins_' is not defined

I'm stuck! :blink: Please Haaaalllllppppp!

The "builtins" name has two underscores before and after, so it's __builtins__ not _builtins_.

WRT your use of "else:", note that your indentation is off... the "else:" statement has to be indented at the same level as the "if" it is associated with. Check out the code on page 28 for an example.

Hope this helps.
