The Nineteenth Byte

R. Kap

06:11

So, what unicode encoding do you think chr() uses in Python 3.5.1 on Mac OS X in English?

Alex A.

UTF-8

Dr Green Eggs and Ham DJ

Not by default.

Alex A.

No?

Dr Green Eggs and Ham DJ

You have to specify to get utf-8.

R. Kap

Utf-8? Which Locale uses ASCII?

Alex A.

06:12

@DrGreenEggsandHamDJ I thought that was a Python 3 thing

Dr Green Eggs and Ham DJ

Oh, yeah you're right.

R. Kap

@DrGreenEggsandHamDJ Then what would be default?

Dr Green Eggs and Ham DJ

@R.Kap For python 3, UTF-8. For python 2, ASCII.

Man, I need to get with the times and stop using python 2.

Alex A.

But for practical purposes ASCII ⊂ UTF-8 so it doesn't matter for ASCII data

R. Kap

@DrGreenEggsandHamDJ So Python 2 uses ASCII. Then I am guessing you can't use values more than 128 with chr() in Python 2.

Dr Green Eggs and Ham DJ

06:14

Well, you can but you get ugly string literals like "\xab"

Alex A.

>>> chr(9082)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: chr() arg not in range(256)

Dr Green Eggs and Ham DJ

@Alex, is that 2 or 3?

Alex A.

2

Dennis

2

Alex A.

>>> chr(9082)
'⍺'

3

R. Kap

06:15

In Python 3, chr(9082) returns '⍺'

Very interesting...

Dr Green Eggs and Ham DJ

How should I give V utf-8 support? Right now, it expects latin8 which is kindof a pain.

I'd like it to handle both, e.g. UTF-8 for convenience, latin8 for golfing.

Dennis

Python 3 doesn't use UTF-8 by default; it honors the system's locale. Virtually every sane OS is configured to use UTF-8 out of the box, but that's beside the point.

$ LANG=en_US.UTF8
$ python3 -q
>>> chr(256)
'Ā'
>>> print(chr(256))
Ā
>>>
$ LANG=en_US
$ python3 -q
>>> chr(256)
'\u0100'
>>> print(chr(256))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'latin-1' codec can't encode character '\u0100' in position 0: ordinal not in range(256)

R. Kap

Apparently, utf-8 supports values up to 1114111. Or in hexadecimal terms, 0x10ffff.

Dr Green Eggs and Ham DJ

@R.Kap Really? I thought UTF8 supports up to four byte width chars.

Alex A.

1114111 is 3 bytes

Dennis

06:18

It does, but it has a lot of redundancy.

Dr Green Eggs and Ham DJ

10 ff ff

Alex A.

I elevened

R. Kap

Well, at least that's what it says in help for chr()

`chr(i, /)`
`Return a Unicode string of one character with ordinal i; 0 <= i <= 0x10ffff.`

Dr Green Eggs and Ham DJ

@AlexA. wat

Alex A.

¯\_(ツ)_/¯

Dennis

06:19

Also, UTF-8 supports 2^32 characters, but Unicode got shortened to 17 * 2^16.

R. Kap

If you try chr() with anything more than 1114111, you get a ValueError.

Alex A.

Good night!

Dr Green Eggs and Ham DJ

Good knight!

R. Kap

Dr Green Eggs and Ham DJ

Wow, I'm bad with chat markup.

R. Kap

Good night!

Dr Green Eggs and Ham DJ

I am ~~bad~~ okay with chat markup.

Dennis

@R.Kap To answer your question, it doesn't use an encoding at all. It simply returns a Unicode string, which only needs to be encoded when converted to a byte string or when printed.

Dr Green Eggs and Ham DJ

Hey, does anyone have thoughts on this before I post it?
http://meta.codegolf.stackexchange.com/a/9000/31716

R. Kap

@Dennis But UTF-8 is the default encoding when it's printed, right?

@DrGreenEggsandHamDJ I like it.

Alex A.

06:26

@DrGreenEggsandHamDJ Looks good to me

Dr Green Eggs and Ham DJ

Cool. BRB, posting

Dennis

@R.Kap No, Python's default is ASCII, but it gets overridden by your system's locale.

R. Kap

Anybody have any thoughts on mine?: meta.codegolf.stackexchange.com/questions/2140/…

Yeah, I just checked. Apparently, all I have to use is sys.getdefaultencoding(), and the output was utf-8.

Alex A.

You just linked to Dr Ham's...

Dr Green Eggs and Ham DJ

@R.Kap I like it!

R. Kap

Ok, here it is: meta.codegolf.stackexchange.com/a/9009/52405 What do you think?

@Dennis So I am assuming, in IDLE, when chr() is used on any integer, str() is first executed on the output, and then the output is returned in that default encoding. And, if the output is not recognizable by the default encoding, an exception is thrown. Interesting...

mınxomaτ

> Some people think "I know, I'll use threads!" and then two they hav erpoblesms.

Dennis

Haha, been there.

R. Kap

What?...

Dennis

06:36

@R.Kap I've never used IDLE, but executing chr with any valid code point should never result in an exception. The encoding only matters if you execute .encode() or if you print.

Alex A.

@mınxomaτ Then they think, "I have too many problems, I'll do everything in serial." Legend has it they're still waiting for their code to finish executing.

Race condition

A race condition or race hazard is the behavior of an electronic, software or other system where the output is dependent on the sequence or timing of other uncontrollable events. It becomes a bug when events do not happen in the order the programmer intended. The term originates with the idea of two signals racing each other to influence the output first. Race conditions can occur in electronics systems, especially logic circuits, and in computer software, especially multithreaded or distributed programs. == Electronics == A typical example of a race condition may occur in a system of logic gates...

Q: How many 14ers did I climb?

In mountaineering terminology, a "14er" is any mountain with an elevation of 14,000 feet or more. However, there is another distinction. For a peak to count as a 14er, it must also have a "geographic prominence" of 300 or more feet. This means that to move from one 14er to another, you must first...
