How can I use the self.max_freq and self.min_freq like a global variable? 
I want to use it in the def main_loop(tb):
but if I use it

That's the given error:
Traceback (most recent call last):
  File "./spectrum_output.py", line 309, in <module>
    main_loop(tb)
  File "./spectrum_output.py", line 246, in main_loop
    print min_freq, max_freq
NameError: global name 'min_freq' is not defined

I tried to put
max_freq = self.max_freq 
min_freq = self.min_freq
in the 
class my_top_block(gr.top_block):

    def __init__(self):
        gr.top_block.__init__(self)

where it's the first time it's used.
