int-整数+bool-布尔功能介绍

int

#创建和转换 
#a = 123
#a = int(123)
#转换 
#Age = “22”
#Age = int(22)

#1.当前整数用二进制表示的最小位数

# age = 50
# v = age.
# print(v)

举例

    def bit_length(self): # real signature unknown; restored from __doc__
        """
        int.bit_length() -> int

        Number of bits necessary to represent self in binary.
        >>> bin(37)
        '0b100101'
        >>> (37).bit_length()
        6
        """
        return 0

bit_length

#2.获取当前数据的字节表示

# age = 15
# v = age.to_bytes(4,b
# v1 = age.to_bytes(4,
# print(v)
# print(v1)
#执行结果
#b'\x00\x00\x00\x0f'
# b'\x0f\x00\x00\x00'

举例

 def to_bytes(self, length, byteorder, *args, **kwargs): # real signature unknown; NOTE: unreliably restored from __doc__
        """
        int.to_bytes(length, byteorder, *, signed=False) -> bytes

        Return an array of bytes representing an integer.

        The integer is represented using length bytes.  An OverflowError is
        raised if the integer is not representable with the given number of
        bytes.

        The byteorder argument determines the byte order used to represent the
        integer.  If byteorder is 'big', the most significant byte is at the
        beginning of the byte array.  If byteorder is 'little', the most
        significant byte is at the end of the byte array.  To request the native
        byte order of the host system, use `sys.byteorder' as the byte order value.

        The signed keyword-only argument determines whether two's complement is
        used to represent the integer.  If signed is False and a negative integer
        is given, an OverflowError is raised.
