Solve the following python programming problem given the following code:
def format_source(debugger_ui, lines, breakpoints) : 
    lineno_format = ('%%%dd ' % len (str (len (lines)))) 
    try : 
        import pygments 
except ImportError : 
        return [SourceLine (debugger_ui, line.rstrip ('
\r').expandtabs (TABSTOP), (lineno_format % (i + 1)), None, has_breakpoint = ((i + 1) in line)) for (i, line) in enumerate (lines)] 
else : 
        from pygments import highlight 
        from pygments.lexers import PythonLexer 
        from pygments.formatter import Formatter 
        import pygments.token as t

                    subself.current_line += s 
                    subself.current_attr.append ((attr, len (s)))

    Fix the buggy line: return [SourceLine (debugger_ui, line.rstrip ('
\r').expandtabs (TABSTOP), (lineno_format % (i + 1)), None, has_breakpoint = ((i + 1) in line)) for (i, line) in enumerate (lines)]
