代码

#int内部功能
name=‘Kamil.Liu‘
age=18
num=-11
print(dir(age))
print(age.bit_length())#返回表示当前数字占用的最少位数
print(num.__abs__())#__abs__:返回绝对值（或abs（-11））
print(age.__add__(num)) 
‘‘‘
__add__:相加（+）   
__bool__：转换为布尔值     
__divmod__:相除，得到商和余数组成的元祖 
__and__：与运算
‘‘‘
print(age.__eq__(18)) #__eq__:  等于（==）
print(type(age.__float__())) #__float__：根据原有数据，创建新的浮点型数据
‘‘‘
__floordiv__：地板除（//）
__ge__：大于等于
__gt__:大于
__init__:构造方法
__pow__：幂运算
__init__:构造方法
‘‘‘
