该程序将一个16进制字符串转换为字符串,并打印出转换结果。 defhex_to_string(hex_str):# 将16进制字符串转换为整数integer=int(hex_str,16)# 将整数转换为字符串string=chr(integer)returnstring hex_str="48656c6c6f"result=hex_to_string(hex_str)print(result)# 输出:Hello 1. 2. 3. 4. 5. 6....
int(STRING,BASE)将字符串STRING转成十进制int,其中STRING的基是base。该函数的第一个参数是字符串 int('0x10', 16) ==> 16 类似的还有八进制oct(), 二进制bin() 16进制字符串转成二进制 hex_str='00fe' bin(int('1'+hex_str, 16))[3:] #含有前导0 # 结果 '0000000011111110' bin(int(hex_s...
There are several ways to represent integers in Python. In this quick and practical tutorial, you'll learn how you can store integers using int and str as well as how you can convert a Python string to an int and vice versa.
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 ...

前面讲到了,我们可以使用变量来指定不同的数据类型,对网工来说,常用的数据类型的有字符串(String), 整数(Integer), 列表(List), 字典(Dictionary),浮点数(Float),布尔(Boolean)。另外不是很常用的但需要了解的数据类型还包括集合(set), 元组(tuple)以及空值(None),下面一一举例讲解。
