[Numpy-discussion] Greek Letters
Hello all, I was wondering how I could print the chi-squared symbol in python. I have been looking at the Unicode docs, but I figured I would ask for assistance here while I delve into it. Thanks for any help in advance.

Re: [Numpy-discussion] Greek Letters
I have found that the python 'unicode name' escape sequence, combined
with the canonical list of unicode names ( http://unicode.org/Public/
UNIDATA/NamesList.txt ), is a good way of getting the symbols you
want and still keeping the python code legible.
From the above list, we see that the symbol name we want is GREEK
SMALL LETTER CHI, so:
chi = u'\N{GREEK SMALL LETTER CHI}'
will do the trick. For chi^2, use:
chi2 = u'\N{GREEK SMALL LETTER CHI}\N{SUPERSCRIPT TWO}'
Note that to print these characters, we usually need to encode them
somehow. My terminal supports UTF-8, so the following works for me:
import codecs
print codecs.encode(chi2, 'utf8')
giving (if your mail reader supports utf8 and mine encodes it
properly...):

With some GUI? Assuming that you have a Unicode-capable terminal, you can find out the encoding it uses by looking at sys.stdout.encoding. Encode your Unicode string with that encoding, and print it. E.g., I use iTerm on OS X and set it to use UTF-8 as the encoding: In [5]: import sys In [6]: sys.stdout.encoding Out[6]: 'UTF-8' In [7]: print u'\u03a7\u00b2'.encode(sys.stdout.encoding) Χ² -- Robert Kern I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth. -- Umberto Eco ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion

Thanks for all the info. That website with all the codes is great.

Re: [Numpy-discussion] Greek Letters
Oh. I am using CygWin, and the website I just went to: http://www.cygwin.com/faq/faq_3.html stated that: The short answer is that Cygwin is not Unicode-aware Not sure if this is going to apply to python in general, but I suspect it will. Ugh, I dislike Windows a lot, but it pays the bills. The interesting thing to note is that the print out to gui interface is 'UTF-8' so it works. It just wont work on my terminal where I do all of my testing. I might just have to put a try statement in and put a chi-square in the except.
