C. unicode is for strings of unicode code points. Note. Just what the dickens is Unicode One mistake that people encountering this issue for the first time make is. In python, the unicode type stores an. Each code point. represents a grapheme. By contrast, byte str stores. Each unicode encoding UTF 8, UTF 7, UTF 1. UTF 3. 2. etc maps different sequences of bytes to the unicode code points. What does that mean to you as a programmer When youre dealing with text. When dealing with IO, reading to and from the disk, printing to. In the python. 2 world many APIs use these two classes interchangably but there. APIs where only one or the other will do the right. When you give the wrong type of string to an API that wants the other. Unicode. Decode. Error. Unicode. Encode. Error.

Python File Write Ascii Codec Can Encode Character' title='Python File Write Ascii Codec Can Encode Character' />However, these exceptions arent always raised. Frustration 1 Inconsistent ErrorsAlthough converting when possible seems like the right thing to do, its. A programmer can test out their. Thequickbrownfoxjumpedoverthelazydog. But when they release their software into the. Isatdownforcoffeeatthecaf and. The reason The mechanism that converts. ASCII characters. Once you throw non ASCII characters into your strings, you have to. So, if I manually convert everything to either byte str or. I be okay The answer is. Frustration 2 Inconsistent APIsThe problem you run into when converting everything to byte str or. API quite. often this includes the APIs in the python standard library and find that the API will only. Or worse. that the code will accept either when youre dealing with strings that consist.

Thus the programmer that wants to. You must keep track of what type your sequences of text are. Does. mysentence contain unicode or str If you dont. Anytime you call a function you need to evaluate whether that function will. Sending. the wrong value here will lead to a Unicode. Error being thrown when. ASCII characters. Note. There is one mitigating factor here. The python community has been. APIs. Although there. APIs that you need to send byte str to in order to be. APIs. Frustration 3 Inconsistent treatment of outputAlright, since the python community is moving to using unicode. Sounds good most of the time but. Anytime you output text to. Python will try to implicitly convert from unicode to. ASCII stringunicoderawinput,utf. Traceback most recent call last. File lt stdin, line 1, in lt module Unicode. Encode.

When you attempt to write non ASCIIunicode strings to a file like object you get a traceback everytime. But what happens when you use print The terminal is a file like object. The answer to that is. No exception. Okay, were fine then We are until someone does one of the following Runs the script in a different locale LCALLC python Note if youre using a good terminal program when running in the C locale The terminal program will prevent you from entering non ASCII characters python will still recognize them if you use the codepoint instead printucafxe.

Now why does redirecting to a file cause problems Its because print in python. Whereas the other. ASCII unless you set. When. print is not outputting to the terminal being redirected to a file.
