hex_string=binascii.b2a_hex(byte_array) 1. 最后,我们将十六进制字符串保存到文本文件中。 withopen('hex_string.txt','w')asfile:file.write(hex_string.decode()) 1. 2. 完整的代码如下所示: importbinasciiwithopen('image.jpg','rb')asfile:
If your hex string has a prefix'0x'in front of it, you can convert it into a bytearray object by using slicing operationhex_string[2:]to get rid of the prefix before converting it usingbytearray.fromhex(hex_string[2:]). hex_string ='0x0f' print(bytearray.fromhex(hex_string[2:]))...
