将 python 'type' 对象转换为字符串 [英] Convert a python 'type' object to a string

问题描述

我想知道如何使用 python 的反射功能将 python 'type' 对象转换为字符串.

I'm wondering how to convert a python 'type' object into a string using python's reflective capabilities.

例如，我想打印一个对象的类型

For example, I'd like to print the type of an object

print "My type is " + type(someObject) # (which obviously doesn't work like this)

推荐答案

print type(someObject).__name__

如果这不适合您，请使用此:

If that doesn't suit you, use this:

print some_instance.__class__.__name__

示例:

class A:
    pass
print type(A())
# prints <type 'instance'>
print A().__class__.__name__
# prints A

此外，在使用新式类与旧式(即从 object 继承)时，type() 似乎存在差异.对于新式类，type(someObject).__name__ 返回名称，而对于旧式类，它返回 instance.

Also, it seems there are differences with type() when using new-style classes vs old-style (that is, inheritance from object). For a new-style class, type(someObject).__name__ returns the name, and for old-style classes it returns instance.
