Reason for that is when dealing with text, people mostly used ASCII characters, which are just one byte. For example you need to represent your Ẁ character in utf-8 format in order to work with them. This is the most common reason I encountered.Ģ- Some text editors only supports utf-8. Non-ascii characters can not be represented by a single byte so we need a special representation for them (utf-16 or utf-8 with more than one byte). Apart from displaying issues, here are some actual reasons and examples:ġ- When you transfer data over internet/network (eg with a socket), information is transferred as raw bytes. Some terminals/command lines or text editors may not support them. The environment you are working on may support those characters, in addition to that your terminal(or whatever you use to see output) may support displaying those characters. But some silly thing for encode and decode, details refer to Why do we need to encode and decode in python? ![]() In python2, str is byte strings, unicode is unicode string. What is the difference between encode/decode in Python 2/3 Again, with separate byte and string types in Python 3, this is no longer an issue. You are right, though: the ambiguous usage of "encoding" for both these applications is. Used like this, str().encode() is also superfluous.īut there is another application of the latter method that is useful: there are encodings that have nothing to do with character sets, and thus can be applied to 8-bit strings in a meaningful way: > s.encode('zip') ![]() UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 0:įor str().encode() it's the other way around - it attempts an implicit decoding of s with the default encoding: > s = 'ö' Unicode().decode() will perform an implicit encoding of s using the default (ascii) codec. It is mainly there for historical reasons, i think. The decode method of unicode strings really doesn't have any applications at all (unless you have some non-text data in a unicode string for some reason - see below). What is the difference between encode/decode?
