Solve the following python programming problem given the following code:
@ property 
def content(self) : 
    def prefixed(prefix, values) : 
        return [(prefix + x) for x in values] 
flags = ['-x', 'c++'] 
    flags.extend (prefixed.deps_build_info.cppflags) 
    flags.extend (self.build_info.cppflags) 
    flags.extend (prefixed ('-D', self.deps_build_info.defines)) 
    flags.extend (prefixed ('-D', self.build_info.defines)) 
    flags.extend (prefixed ('-I', self.build_info.include_paths)) 
    flags.extend (prefixed ('-I', self.deps_build_info.include_paths)) 
    return self.template.format (default_flags = (("'" + "', '".join (flags)) + "'")) 

    
    

    Fix the buggy line: flags.extend (prefixed.deps_build_info.cppflags)

#Here is Python program to fix the buggy line: flags.

flags.extend (self.deps_build_info.cppflags)
