StringIO操作的只能是str,如果要操作二进制数据,就需要使用BytesIO。 BytesIO实现了在内存中读写bytes,我们创建一个BytesIO,然后写入一些bytes: >>> from io import BytesIO >>> f = BytesIO() >>> f.write('中文'.encode('utf-8')) # 6 >>> print(f.getvalue()) # b'\xe4\xb8\xad\xe6\x...

5. Convert Bytes Array to String To convert a byte array to a string, you can use thebytes()constructor to create a bytes object from the array, and then use thedecode()method to convert the bytes object to a string. # Create a byte arraybyte_array=bytearray([115,112,97,114,107]...
