[D]python type() 函数问题

[zz8880]

我怎么把一个变量的类型写入文件？
a = 3
type(a)
貌似返回的是type类型，不能打印，也不能用文件的write怎么半，或者怎么转换成srt之类的？

转字串表示，一般通用就是repr()，或者type类型有个__name__属性：
>>> repr(type(3))
"<class 'int'>"
>>> type(3).__name__
'int'
>>>

如果你是要保存数据，试试pickle模块，可免去这些琐碎的解析...

print(type(a))

用__dict__打印所有内置属性,找到你需要的__name__后print出来就行了

>>> ================================ RESTART ================================
>>> for k,v in type.__dict__.items():
	print k,v
