Solve the following python programming problem given the following code:
def _create_slice_cb_closure(c) : 
    src = c.src_node._signalvalue 
    dest = c.dest_node._signalvalue 
    src_addr = (dest_bits.src_slice if (c.src_slice != None) else slice (None)) 
    dest_bits = (dest [c.dest_slice] if (c.dest_slice != None) else dest) 
    def slice_cb() : 
        dest_bits.v = src [src_addr] 
return slice_cb 

    
    

    Fix the buggy line: src_addr = (dest_bits.src_slice if (c.src_slice != None) else slice (None))

#Here is Python code to fix the buggy line: src_addr = (dest_bits.

src_addr = (c.src_slice if (c.src_slice != None) else slice (None))
