Solve the following python programming problem given the following code:
def asFloat(self, maxval = 1.0) : 
    'Return image pixels as per :meth:`asDirect` method, but scale
        all pixel values to be floating point values between 0.0 and
        *maxval*.
        ' 
    (x, y, pixels, info) = self.asDirect () 
    sourcemaxval = ((2 ** info ['bitdepth']) - 1) 
    del info ['bitdepth'] 
    info ['maxval'] = float (maxval) 
    factor = (float (maxval) / float (info)) 
    def iterfloat() : 
        for row in pixels : 
            (yield [(factor * p) for p in row]) 
return (x, y, iterfloat (), info) 

    
    

    Fix the buggy line: factor = (float (maxval) / float (info))
assistant
#Here is Python code to fix the buggy line: factor = (float (maxval) / float (info))
.

factor = (float (maxval) / float (sourcemaxval))
