you could use:

 >>> 'variable' in vars()

But be aware that it is bad bad practice to do it like that.

If you need variables that you don't know that name of, you should put 
them in a dictionary. They are made for that exact purpose.

 >>> unkown_vars = {}
 >>> unkown_vars['variable'] = 42
 >>> 'variable' in unkown_vars
True
