which one is more efficient
I have type variable which may have been set to 'D' or 'E'
Now, which one of following statements are more efficient
if type =='D' or type == 'E':
or
if re.search("D|E", type):
Please let me know because the function is going to called 10s of millions

What *is* INT64? It's not a builtin type of standard C, it isn't defined by Microsoft C, and it isn't predefined by Python. So it must be something that you have defined, and apparently incorrectly. How did you define it? Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list

I assume you print to the terminal (cmd.exe). This cannot work;
the terminal (usually) does not interpret the characters in UTF-8.
Instead, you should print a Unicode string, e.g.
print u"\N{GREEK CAPITAL LETTER DELTA}"
or
print u'\u0394'
This should work as long as your terminal supports printing
the letter at all.

Martin

Yes, when writing to a file, you need to define an encoding, e.g.
self.file.write(data.encode("utf-8"))
You can use codecs.open() instead of open(),
so that you can just use self.file.write(data)
Alternatively, you can find out what sys.stdout.encoding is,
and use that when encoding data for the terminal (falling back
to "utf-8" when .encoding is not available on the file).

Your version of Windows uses a code page that supports Chinese
characters in the byte-oriented character set. These are normally
encoded using the "mbcs" encoding (except that the terminal likely
uses a different encoding). So if you use "mbcs" instead of "utf-8",
you might be able to read the text as well.

Re: How to print this character u'\u20ac' to DOS terminal

The problem is that your terminal uses (some form of) the GBK encoding; see http://zh.wikipedia.org/wiki/GBK for details on GBK. It seems that GBK (or, rather, code page 936) supports the delta character, but not the euro sign. To change that, you can use "chcp" in your terminal window. For example, if you do "chcp 850", you should be able to display the euro sign (but will simultaneously use the ability to display the letter delta, and the chinese letters). I don't know whether the terminal supports an UTF-8 code page; you can try setting the terminal's code page to 65001 (which should be UTF-8).

Try removing the definition of Py_DEBUG that is implied by _DEBUG. Notice, however, that it is risky to mix different CRT versions (debug and nodebug) in a single application; this could cause memory leaks and crashes. In particular, it *will* cause crashes if you pass FILE* opened by the debug CRT to PyRun_File and friends. That's an inherent limitation of Windows DLLs, and the way Microsoft set up global variables in the VC CRT. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
