Solve the following python programming problem given the following code:
def erlang_config(hash, depth = 1) : 
    def printable(item) : 
        (k, v) = item 
        if isinstance (v, string_types) : 
            p = ('"%s"' % v) 
else : 
            if isinstance (v, dict) : 
                p = erlang_config (v, (depth + 1)) 
else : 
                if isinstance (v, bool) : 
                    p = ('%s' % v).lower () 
else : 
                    p = ('%s' % v) 
return ('{%s, %s}' % (k, p)) 
padding = ('    ' * depth) 
    parent_padding = ('    ' * (printable - 1)) 
    values = (',
%s' % padding).join (map (printable, hash.items ())) 
    return ('[
%s%s
%s]' % (padding, values, parent_padding)) 

    
    

    Fix the buggy line: parent_padding = ('    ' * (printable - 1))
assistant
#Here is Python program to fix the buggy line: parent_padding = ('    ' * (printable - 1))
.

parent_padding = ('    ' * (depth - 1))
