Str_encoded= str.encode('utf_16','strict') In both the cases, the encoding used is the 'utf_16' and the error used is 'strict'.
The decoded string is obtained as output and printed using the print() function. The encoded string is now taken and the decode() function is invoked to that string. In the following example, a string "Hello! Welcome to Tutorialspoint." is created and it is encoded using the encode() function. If the error is specified as 'strict', then the encoding errors raise a UnicodeError. The python string decode() method that takes 'utf_16' as its encoding has a variable length encoding done.
The python string decode() method returns a decoded string. Other possible values are 'ignore', 'replace', 'xmlcharrefreplace', 'backslashreplace' and any other name registered via codecs.register_error(). The default for errors is 'strict' which means that the encoding errors raise a UnicodeError. For a list of all encoding schemes, please visit: Standard Encodings.Įrrors − This parameter specifies an error handling scheme. The following are the parameters of the python string decode() function.Įncoding − This parameter specifies the encodings to be used. Str.decode(encoding='UTF-8',errors='strict') The syntax of the python string decode() method is as follows. In the following section, we will be learning more details about the python string decode() method. Finally, this method returns the decoded string. During this process, different error handling schemes can be set using the errors parameter. Based on the specified encoding, the string is decoded. There are various types of standard encodings such as base64, ascii, gbk, hz, iso2022_kr, utf_32, utf_16, and many more. This function works based on the parameters specified which are encoding and the error. The encoded string can be decoded and the original string can be obtained with the help of this function.
#Python encode decode code
Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.The python string decode() method decodes the string using the codec registered for its encoding. The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".
In other words, calling an object method means thinking in terms "let the object gives me the wanted result". In my opinion, this is a nice example that show the alternative thinking about technically the same thing. It depends on mental picture of the solved problem.Īnyway, the feature mentioned in the question is probably a by-product of the language implementation/design. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. more natural and more versatile than pure OO or pure procedural languages. A programming language is considered good if it contains constructs that one needs. It may also look that the second way is a syntactic sugar for the third approach.Ī programming language is a means to express abstract ideas formally, to be executed by the machine. To add to Lennart Regebro's answer There is even the third way that can be used: encoded3 = str.encode(original, 'utf-8')Īnyway, it is actually exactly the same as the first approach. Now my question is, why are there 2 methods that seem to do the same thing, and is either better than the other (and why?) I've been trying to find answer to this on google, but no luck. U'something'.encode('utf-8') will generate b'something', but so does bytes(u'something', 'utf-8').Īnd b'bytes'.decode('utf-8') seems to do the same thing as str(b'bytes', 'utf-8'). So the idea in python 3 is, that every string is unicode, and can be encoded and stored in bytes, or decoded back into unicode string again. I've read some good posts, that made it all much clearer, however I see there are 2 methods on python 3, that handle encoding and decoding, and I'm not sure which one to use. I am new to python3, coming from python2, and I am a bit confused with unicode fundamentals.
