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 Pyth
接着我们测试了一个补码转换的例子,并输出结果。 关系图 下面是补码转换成十进制的关系图: erDiagram BINARY_CODE { string binary_code } DECIMAL_NUMBER { int decimal_number } BINARY_CODE ||--|| DECIMAL_NUMBER : Convert to 结论 通过本文介绍的方法和代码示例,我们可以很方便地将Python的补码转换成十...
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 returns an integer. oct(x) Convert an integer number to an octal string. The result is a valid Python expression. If...
Run Code Here, we can see above that1(integer) is converted into1.0(float) for addition and the result is also a floating point number. Explicit Type Conversion We can also use built-in functions likeint(),float()andcomplex()to convert between types explicitly. These functions can even con...

int_value = int(binary_num, 2) print(int_value) In the above code: The binary number “1111” is initialized and stored in the variable “binary_num”. The “int()” function takes the variable “binary_num” and base value “2” as an argument to convert the binary into an integer...
以下函数都是在Built-in Functions里面 hex(x) Convert an integer number to a lowercase hexadecimal string prefixed with “0x”. If x is not a Python int object, it has to define an __index__() method that returns an integer bin(x) Convert an integer number to a binary string prefixed...
decimal = int(binary, 2) print(decimal) Output: 240 In this program, we define a binary number as a string. We then use the int() function to convert the binary number to an integer. The first parameter of the int() function is the binary number, and the second parameter is the ba...
