在Python中测试变量类型

为什么是这样？

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
            #Check for input errors:
    if type(self.code) != type(str()):
        print 'Error found in module rooms.py!'
        print 'Error number: 110'
    elif type(self.name) != type(str()):
        print 'Error found in module rooms.py!'
        print 'Error number: 111'
    elif type(self.type) != type(str()):
        print 'Error found in module rooms.py!'
        print 'Error number: 112'
    elif type(self.size) != type(int()):
        print 'Error found in module rooms.py!'
        print 'Error number: 113'
    elif type(self.description) != type(str()):
        print 'Error found in module rooms.py!'
        print 'Error number: 114'
    elif type(self.objects) != type(list()):
        print 'Error found in module rooms.py!'
        print 'Error number: 115'
    elif type(self.exits) != type(tuple()):
        print 'Error found in module rooms.py!'
        print 'Error number: 116'

当我运行这个时,我收到此错误：

Traceback (most recent call last):
  File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa   I/rooms.py",line 148,in <module>
    myRoom = Room(101,'myRoom','Basic Room',5,'<insert description>',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

—-感谢您的帮助,但是：—–

这适用于isinstance(item,list)或isinstance(item,tuple)吗？
