Solve the following python programming problem given the following code:
def hexdump(data) : 
    def _cut(sequence, size) : 
        for i in xrange (0, len (sequence), size) : 
            (yield sequence [i : (i + size)]) 
_hex = (lambda seq : ['{0:02x}'.format (b) for b in seq]) 
    _chr = (lambda seq : [(chr (b) if (32 <= b <= 126) else '.') for b in seq]) 
    raw_data = map (ord, data) 
    hexpanel = [' '.join (line) for line in _cut (_hex (raw_data), 16)] 
    chrpanel = [''.join (line) for line in _cut (_chr (raw_data), 16)] 
    hexpanel [(- 1)] = (hexpanel [(- 1)] + (chr (32) * (47 - len (hexpanel [(- 1)])))) 
    chrpanel [(- 1)] = (chrpanel [(- 1)] + (chr (32) * (16 - len (chrpanel [(- 1)])))) 
    return '
'.join ((('%s  %s' % (data, c)) for (h, c) in zip (hexpanel, chrpanel))) 

    
    

    Fix the buggy line: return '
'.join ((('%s  %s' % (data, c)) for (h, c) in zip (hexpanel, chrpanel)))
assistant
#Here is Python code to fix the buggy line: return '
.

return '
'.join ((('%s  %s' % (h, c)) for (h, c) in zip (hexpanel, chrpanel)))
