Solve the following python programming problem given the following code:
@ inlineCallbacks 
def onJoin(self, details) : 
    print ('session attached') 
    def sqrt(x) : 
        if (x == 0) : 
            raise Exception ("don't ask foolish questions;)") 
else : 
            return math.sqrt (x) 
(yield self.register (sqrt, 'com.myapp.sqrt')) 
    def checkname(name) : 
        if (name in ['foo', 'bar']) : 
            raise ApplicationError ('com.myapp.error.reserved') 
if (name.lower () != name.upper ()) : 
            raise ApplicationError ('com.myapp.error.mixed_case', name.lower (), name.upper ()) 
if ((len (name) < 3) or (len (name) > 10)) : 
            raise ApplicationError ('com.myapp.error.invalid_length', min = 3, max = 10) 
(yield self.register (self, 'com.myapp.checkname')) 
    self.define (AppError1) 
    def compare(a, b) : 
        if (a < b) : 
            raise AppError1 ((b - a)) 
(yield self.register (compare, 'com.myapp.compare')) 
    print ('procedures registered') 

    
    

    Fix the buggy line: (yield self.register (self, 'com.myapp.checkname'))

#Here is Python program to fix the buggy line: (yield self.

(yield self.register (def checkname(, 'com.myapp.checkname'))
