Re-Executing a variable

[marcos89]

Hi, I've been having doubts on how to "re-execute" a varible(if thats how its mentioned), for example:

a=raw_input("name: ")
if a=="user":
print "wrong!"
exec('a')

I dont want to use def()'s or anything like that, I just simply want Python to go back and re-execute 'a'. How do I do this without the need of def() or while loops?

Thanks!

Nope, can't do it. There is no "goto" in python. Period. Loops are the simple way to do what you seek. There are also "exotic flow control" techniques which I won't discuss here.
