Python的type函数结果你知道嘛

type() 不会认为子类是一种父类类型，不考虑继承关系。
isinstance() 会认为子类是一种父类类型，考虑继承关系。
如果要判断两个类型是否相同推荐使用 isinstance()。

import time
import random
import asyncio
import collections
# 基本数据类型
print(type(1))  # <class 'int'>
print(type(3.14))  # <class 'float'>
print(type("hello"))  # <class 'str'>
print(type([1, 2]))  # <class 'list'>
print(type((1, "a")))  # <class 'tuple'>
print(type({"name": "tom"}))  # <class 'dict'>
print(type(False))  # <class 'bool'>
print("*" * 30)
# <class 'module'>
print(type(time))
print(type(random))
print(type(asyncio))
print("*" * 30)
# <class 'type'>
print(type(type))
print(type(int))
print(type(float))
print(type(bool))
print(type(str))
print(type(dict))
print(type(list))
print(type(tuple))
print(type(set))
print("*" * 30)

# 自定义的类型：<class '__main__.XXX'>

print(type(a.__init__()))
print(type(a.run()))
print(type(a.say()))
print(type(a.live()))
print(type(a.sleep))
print(type(A.x))  # <class 'int'> 与初始值类型一致
print(type(a.x))  # <class 'int'> 与初始值类型一致
print("*" * 30)
# <class 'builtin_function_or_method'>
print(type(None))
print(type(bin))
print(type(len))
print(type(min))
print(type(dir))
print("*" * 30)
data = "message"
result = collections.Counter(data)
dict1 = collections.OrderedDict({"name": "Tom", "age": 25, "address": "CN"})

print(type(deq1))  # <class 'collections.deque'>

from types import LambdaType, MethodType, GeneratorType, FunctionType, BuiltinFunctionType
test1 = lambda x: x + 1
# 判定是否是lambda类型。需要注意的是lambda就是函数类型，本质是一样的
print(type(test1) == LambdaType)  # True
# 判定是否是函数类型
print(type(test1) == FunctionType)  # True
# 判定是否是内置函数类型
print(type(bin) == BuiltinFunctionType)  # True

class Test2:
    def run(self):
        pass

test2 = Test2()
# 判定是否是方法
print(type(test2.run) == MethodType)
# 判定生成器类型
a = (x * x for x in range(1, 10))
print(type(a) == GeneratorType)
