  • 如果传入的是一个对象，׃昄q个对象的类型的帮助?/span>

比如输入help(’print’)Q它?yu)׃L?#8217;print’为名的模块，c，{，找不到就会看到提CZ息。而print在python里是一个保留字Q和pass,return同等Q而非对象Q所以help(print)也会出错((kkkkkkk))?/span>

foo(int a)一看就知道传入整Şq回字符Ԍ换成Python变成了 foo(a)Q只能读文档才能搞清楚了。可能我q没习惯的原因吧Q感觉有时文对它们的类型也说的不太清楚?br><br>M感觉Python一些风格像C。写起代码来Q感觉很快，很清楚，q是很不错的 I love the feeling :)</div><br><br><div style="border: 1px solid
