How to use decode function

The decode function is used to convert a byte stream or byte array into a string. Under different encoding methods, the byte stream can represent different character sets, and the decode function can convert the byte stream into the corresponding string according to the specified encoding method.

In Python, the decode function can be used in the following ways:

bytes_object.decode(encoding, errors)

Among them, bytes_object is the byte stream or byte array to be converted, encoding is the specified encoding method, and errors can be Optional parameter, used to specify the processing method when decoding errors occur. The default is "strict", which means an exception is thrown when an error is encountered.

For example, if there is a string represented by a byte stream, the encoding method is UTF-8, you can use the decode function to decode:

byte_stream = b'\xe4\xb8\xad\xe6\x96\x87'  # UTF-8编码的字节流
decoded_string = byte_stream.decode('utf-8')  # 解码为字符串
print(decoded_string)  # 输出：中文

It should be noted that the decoding should be based on the actual situation Select appropriate parameters for the encoding method, otherwise garbled codes or decoding errors may occur.
