Solve the following python programming problem given the following code:
@ staticmethod 
def computeFSum(X, y, classZeroLabel) : 
    nRows = X.shape [0] 
    def columnSum(column) : 
        def f(rowIx) : 
            if (y [rowIx] == classZeroLabel) : 
                return float (column [rowIx]) 
return 0.0 
return sum ((f (rowIx) for rowIx in xrange (nRows))) 
return numpy.array ([columnSum (y) for column in X.columns ()]) 

    
    

    Fix the buggy line: return numpy.array ([columnSum (y) for column in X.columns ()])

#Here is Python code to fix the buggy line: return numpy.

return numpy.array ([columnSum (column) for column in X.columns ()])
