Yes, class A can access main.  The name "main" will be defined at the 
top level of the module, and is considered a global for that module.  
Code within that module can access it simply as "main".  Code in other 
modules would have to import the module in order to use symbols within 
it.  For example...

### myModule.py ####

class A:
  def m():
    main()

def main():
  pass


### other.py ###

import myModule

def main():
  pass

class B:
  def o():
    main() # calls main() in this module
    myModule.main() # calls main in myModule
