使用Python内置函数:bin()、oct()、int()、hex()可实现进制转换。 先看Python官方文档中对这几个内置函数的描述: bin(x) Convert an integer number to a binary string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that ...
a = int(input("Enter 1 for denary into binary, 2 for binary into denary, or 3 to quit..."))b = []c = []while a != 3: if a == 1: print("You have selected denary to binary.") b = int(input("Enter the denary number you want to convert into binary: ")) if type(b)...
hex(x) Convert an integer number to a hexadecimal string. The result is a valid Python expression. If x is not a Python int object, it has to define an __index__() method that returns an integer. ↓ 2进制 8进制 10进制 16进制 2进制 - bin(int(x, 8)) bin(int(x, 10)) bin(...
hex(x) Convert an integer number to a lowercase hexadecimal string prefixed with “0x”, for example If x is not a Python int object, it has to define an __index__() method that returns an integer. 说明: 1. 函数功能将10进制整数转换成16进制整数。

若将十进制的浮点数转化为二进制,是否可以用bin()?不能!官方文档中很明确地指出:Convert an integer number to a binary string prefixed with “0b”.(https://docs.python.org/3/library/functions.html#bin),还可以试试: 代码语言:javascript
