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 ...
我们可以使用这个函数将两个字符组成的字符串转换为16进制。 defconvert_to_hex(string):hex_string=""foriinrange(0,len(string),2):ifi+1<len(string):combined=string[i:i+2]hex_value=hex(int(combined.encode().hex(),16))hex_string+=hex_value[2:]# 去掉0x前缀returnhex_string# 示例str="Hel...
string="Hello, World!"integer=int.from_bytes(string.encode(),'big')hexadecimal=hex(integer)print(hexadecimal) 1. 2. 3. 4. 上述代码中,我们首先使用字符串的encode()方法将字符串转换为字节数组,然后使用int.from_bytes()函数将字节数组表示的整数转换为整数类型。最后,我们使用hex()函数将整数转换为十六...
