在Python中测试变量类型

我正在为类'Room'创建一个初始化函数,并发现程序无法接受我对输入变量的测试。

为什么会这样呢?

def __init__(self, code, name, type, size, description, objects, exits):
    self.code = code
    self.name = name
    self.type = type
    self.size = size
    self.description = description
    self.objects = objects
    self.exits = exits
            #检查输入错误:
    if type(self.code) != type(str()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:110'
    elif type(self.name) != type(str()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:111'
    elif type(self.type) != type(str()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:112'
    elif type(self.size) != type(int()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:113'
    elif type(self.description) != type(str()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:114'
    elif type(self.objects) != type(list()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:115'
    elif type(self.exits) != type(tuple()):
        print '在rooms.py模块中发现错误!'
        print '错误编号:116'

当我运行这个程序时,我得到了这个错误:

Traceback (most recent call last):
  File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa   I/rooms.py", line 148, in 
    myRoom = Room(101, 'myRoom', 'Basic Room', 5, '', myObjects, myExits)
  File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa I/rooms.py", line 29, in __init__
    if type(self.code) != type(str()):
TypeError: 'str' object is not callable

---- 感谢你的帮助,但是: -----

这是否适用于isinstance(item, list)或isinstance(item, tuple)?
