Convert string to bytes python12/18/2023 In case of failure, a UnicodeDecodeError exception may occur. ![]() Use encode () to convert a String to UTF-8 The encode () method returns the encoded version of the string. As the input string is so short, the output is also short and contains just one byte. Single Char String to a Byte The string in this example contains just one character 'a'. Add a Whitespace Select this option to add a whitespace char after each byte. import six def bytestostr (s, encoding'utf-8'): '''Returns a str if a bytes object is given.''' if six.PY2 and isinstance (s, bytes): return s. In : recovered_text = ast.literal_eval(recovered_from_json). Therefore, in order to convert the plain string to utf-8, we will use the encode () method to convert a string to utf-8 in python 3. Use Full Bytes If a byte is less than 0xf, make it 0x0f. It is intended to support codebases that work on both Python 2 and 3 without modification. Second is argument for error handling, default is ‘strict’ handling. It accepts two parameters : First is bytes that needs to be converted. It is also used to convert bytes to a string in python. In : # and if you have data like this in files/databases you need to recover: Convert Bytes to String using the code () method The decode () is a function of the codec module in Python. This function internally points to the CPython library, which implicitly calls the encoding function to convert the string to the specified encoding. In : recovered_from_json = json.loads(json_data) Python Convert string to bytes Michael Zippo Method 1: Using bytes (str, enc) A string can be converted to bytes using the generic byte function. The bytes data types allow values only from 0 to 255. When we want to represent a group of byte values then we can consider bytes data types. # as you can see, it is doubly escaped, and it is mostly useless in this form We will convert the string to a bytes object using the byte () built-in function and encode () method. I will print the result from each step so you can undestand the transforms that are taking place. # text is a Unicode text string ready to be used!Īs you are doing, you are probably gettint the text doubly-encoded - I will mimick it on the Python 3 console. # code to transmit json string by network or file as it is. # No str-encode-decode dance needed here.ĭata = json.dumps() In short: to pass data around, simply encode your original text as JSON in the first program, and do not botter with any decoding after json.load on the target Python 2 program: # my first program Python's JSON load methods already decode the contents of json data into text-strings: so a decode method is not to be expected at all. By calling str(.) on it, you are just putting a escaping layer on this bytes object, and turning it back to a string - but when this string is written as is to a file, or transmited over the network, it will be encoded again - any non-ASCII tokens are usually escaped with the \u prefix and the codepoint for each character - but the original Chinese chracters themselves are now encoded in utf-8 and doubly-escaped. ![]() encode step in program 1, you have a bytes object. The most important part to properly answer this is the information on how you pass these objetcts to the Python2 program: you are using JSON.Īfter you do the.
