![]() ![]() ![]() Ls command may produce output that can't be interpreted as text. To interpret a byte sequence as a text, you have to know theĬorresponding character encoding: unicode_text = code(character_encoding) Lines.append(code('utf-8', 'slashescape')) #print err, dir(err), err.start, err.end, err.objectĬodecs.register_error('slashescape', slashescape) returnĪ tuple with a replacement for the unencodable part of the inputĪnd a position where encoding should continue""" It should be slower than the cp437 solution, but it should produce identical results on every Python version. UPDATE 20170119: I decided to implement slash escaping decode that works for both Python 2 and Python 3. See Python’s Unicode Support for details. That works only for Python 3, so even with this workaround you will still get inconsistent output from different Python versions: PY3K = sys.version_info >= (3, 0) UPDATE 20170116: Thanks to comment by Nearoo - there is also a possibility to slash escape all unknown bytes with backslashreplace error handler. UPDATE 20150604: There are rumors that Python 3 has the surrogateescape error strategy for encoding stuff into binary data without data loss and crashes, but it needs conversion tests, -> ->, to validate both performance and reliability. ![]() See the missing points in Codepage Layout - it is where Python chokes with infamous ordinal not in range. ![]() The same applies to latin-1, which was popular (the default?) for Python 2. UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 2: invalid String_bytes = base64.If you don't know the encoding, then to read binary input into string in Python 3 and Python 2 compatible way, use the ancient MS-DOS CP437 encoding: PY3K = sys.version_info >= (3, 0)īecause encoding is unknown, expect non-English symbols to translate to characters of cp437 (English characters are not translated, because they match in most single byte encodings and UTF-8).ĭecoding arbitrary binary input to UTF-8 is unsafe, because you may get this: > b'\x00\x01\xffsd'.decode('utf-8') We can also decode a base64 string using the base64 module. We use the decode() method to get the encoded string from this byte-like object. Next, we have encoded it into base64 encoding using the base64 module which gives us a byte-like object. In the above program, we have first converted the given string into byte-like objects. Output: Base64 Encoded String: Q29kZXNwZWVkeSBpcyBmdW4u Print("Base64 Encoded String: ", b64_string) import base64ī64_bytes = base64.b64encode(string_bytes) Have a look at the Python program given below. Python provides us with a module named ‘base64’ to encode and decode strings. Next, we will see how we can encode strings to Base64 and decode Base64 strings using Python. We can use the below Base64 encoding table to align the values. Now, convert the 6-bit character chunks to decimal value.Regroup the digits to convert 8-bit character chunk into 6-bit character chunk.Get the 8-bit binary equivalent of obtained ASCII value.We can easily convert a given string into a Base64 string by following the below steps for every character: How to convert a string into a Base64 string? The available characters in Base64 encoding are given below: In Base64 encoding, we convert the given bytes into ASCII characters. In this post, we will learn Base64 encoding and decoding for strings in Python. ![]()
