Decode the bytes object to produce a string:
>>> b"abcde".decode("utf-8")
'abcde'
The above example assumes that the bytes object is in UTF-8, because it is a common encoding. However, you should use the encoding your data is actually in!

Decode the byte string and turn it in to a character (Unicode) string.
Python 3:
encoding = 'utf-8'
b'hello'.decode(encoding)
or
str(b'hello', encoding)
Python 2:
encoding = 'utf-8'
'hello'.decode(encoding)
or
unicode('hello', encoding)

Try this: line = ser.readline().strip() values = line.decode('ascii').split(',') a, b, c = [int(s) for s in values] The call to .strip() removes the trailing newline. The call .decode('ascii') converts the raw bytes to a string. .split(',') splits the string on commas. Finally the call [int(s) for s in value] is called a list comprehension, and produces a list of integers. More on reddit.com

It's interesting that though the question might seem reasonable, it's not that easy to figure out a practical reason why I would need to convert a StringIO into a BytesIO. Both are basically buffers and you usually need only one of them to make some additional manipulations either with the bytes or with the text.
I may be wrong, but I think your question is actually how to use a BytesIO instance when some code to which you want to pass it expects a text file.
In which case, it is a common question and the solution is codecs module.
The two usual cases of using it are the following:
Compose a File Object to Read
In [16]: import codecs, io
In [17]: bio = io.BytesIO(b'qwe\nasd\n')
In [18]: StreamReader = codecs.getreader('utf-8') # here you pass the encoding
In [19]: wrapper_file = StreamReader(bio)
In [20]: print(repr(wrapper_file.readline()))
'qwe\n'
In [21]: print(repr(wrapper_file.read()))
'asd\n'
In [26]: bio.seek(0)
Out[26]: 0
In [27]: for line in wrapper_file:
...: print(repr(line))
...:
'qwe\n'
'asd\n'
Compose a File Object to Write To
In [28]: bio = io.BytesIO()
In [29]: StreamWriter = codecs.getwriter('utf-8') # here you pass the encoding
In [30]: wrapper_file = StreamWriter(bio)
In [31]: print('ะถะฐะฑะฐ', 'ัะฐะฟ', file=wrapper_file)
In [32]: bio.getvalue()
Out[32]: b'\xd0\xb6\xd0\xb0\xd0\xb1\xd0\xb0 \xd1\x86\xd0\xb0\xd0\xbf\n'
In [33]: repr(bio.getvalue().decode('utf-8'))
Out[33]: "'ะถะฐะฑะฐ ัะฐะฟ\\n'"

self.errors = errors or text_io_buffer.errors or 'strict'

raw_method = getattr(self.raw, method_name)
val = raw_method(*args, **kwargs)
return val.encode(self.encoding, errors=self.errors)

Hi Kraj,
Youโre almost there, you have to convert the bytes from base64 to a string:
as_string = str(base64.b64encode(signature), 'utf8')
And back:
signature == base64.b64decode(bytes(enc, 'utf8'))

Hi Raj,
Iโm not sure what you want to do here, but know that you only can verify a (received) signature by generating it again using the same technique and then compare it with what you created. You cannot โdecodeโ a signature.

UTF-8 is the default encoding, but other encodings can be used. We can also convert a string to a bytes object using the string method .encode() with various encodings:

February 23, 2024 - In this snippet, TextIOWrapper wraps around a BytesIO object to deal seamlessly with encoding. This is particularly useful for complex text processing that involves different encodings and newline handling. This approach is slightly more complex and involves creating a memoryview object from the bytes data before decoding it. This method can be efficient for large data sets as it provides a way to work with a slice of the bytes without copying the original data. ... from io import StringIO bytes_data = b'This is a memoryview example' memory_view = memoryview(bytes_data) string_data = memory_view.tobytes().decode('utf-8') string_io = StringIO(string_data) print(string_io.getvalue())
