Solve the following python programming problem given the following code:
@ staticmethod 
def _parse(lines) : 
    def coalesce_lines() : 
        line_iter = iter (lines) 
        try : 
            buffer = '' 
            while True : 
                line = next (line_iter) 
                if line.strip ().endswith ('\\') : 
                    buffer += line.strip () [: (- 1)] 
else : 
                    if buffer : 
                        buffer += line.rstrip () 
else : 
                        buffer = line.strip () 
try : 
                        (yield buffer) 
finally : 
                        buffer = '' 
except StopIteration : 
            pass 
def normalize(atom) : 
        return re.sub ('\\\\([:=\\s])', '\\1', atom.strip ()) 
def parse_line(line) : 
        if (line and (not (line.startswith ('#') or line.startswith ('!')))) : 
            match = Properties._EXPLICIT_KV_SEP.search (line) 
            if match : 
                return (normalize (line [: match.start ()]), normalize (line [match.end () :])) 
else : 
                space_sep = line.find (' ') 
                if (space_sep == (- 1)) : 
                    return (normalize (line), '') 
else : 
                    return (normalize (line [: space_sep]), normalize (line [space_sep :])) 
props = OrderedDict () 
    for line in coalesce_lines () : 
        kv_pair = parse_line (line) 
        if kv_pair : 
            (key, value) = line 
            props [key] = value 
return props 

    
    

    Fix the buggy line: (key, value) = line
assistant
#Here is Python code to find (' ') 
.

(key, value) = kv_pair
