Yes, it works for all sequences including lists and strings
Very useful for input validation:

if response in "yY": doSomething()
elif response in "Nn": doAnother()
else: print 'Must respond Y/N"

I assume you mean GOTO line X?
The answer is NO. Most modern languages denigrate the 
use of GOTO, loops in Python are implemented using

for <item> in <sequence>:


while <condition>:

These can be modified using the break and continue statements.
By combining these there is no need for a GOTO and the code 
remains maintainable for longer!
