Assuming Python sees the name as a normal string, you’ll first have to decode it to unicode: >>> name ‘Christensen Sk\xf6ld’ >>> unicode(name, ‘latin-1′) u’Christensen Sk\xf6ld’ Another way of achieving this: >>> name.decode(‘latin-1′) u’Christensen Sk\xf6ld’ Note the “u” in front of the string, signalling it is uncode. If you print this, the accented letter is … Read more

The string you’re trying to parse as a JSON is not encoded in UTF-8. Most likely it is encoded in ISO-8859-1. Try the following: json.loads(unicode(opener.open(…), “ISO-8859-1”)) That will handle any umlauts that might get in the JSON message. You should read Joel Spolsky’s The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode … Read more
In Python versions prior to 3.0 there are two kinds of strings “plain strings” and “unicode strings”. Plain strings (str) cannot represent characters outside of the Latin alphabet (ignoring details of code pages for simplicity). Unicode strings (unicode) can represent characters from any alphabet including some fictional ones like Klingon. So why have two kinds … Read more
If you create the following file xx.in: test line 1 test line 2 and run the following Python program, you’ll see exactly why the match is failing: file = open(‘xx.in’) for line in file: print ‘[%s]’ % (line) The output is: [test line 1 ] [test line 2 ] showing that the newline characters are … Read more
You can just use image to index into lut if lut is 1D. Here’s a starter on indexing in NumPy: http://www.scipy.org/Tentative_NumPy_Tutorial#head-864862d3f2bb4c32f04260fac61eb4ef34788c4c In [54]: lut = np.arange(10) * 10 In [55]: img = np.random.randint(0,9,size=(3,3)) In [56]: lut Out[56]: array([ 0, 10, 20, 30, 40, 50, 60, 70, 80, 90]) In [57]: img Out[57]: array([[2, 2, 4], … Read more
super() is not broken — it just should not be considered the standard way of calling a method of the base class. This did not change with Python 3.x. The only thing that changed is that you don’t need to pass the arguments self, cls in the standard case that self is the first parameter … Read more
zip computes all the list at once, izip computes the elements only when requested. One important difference is that ‘zip’ returns an actual list, ‘izip’ returns an ‘izip object’, which is not a list and does not support list-specific features (such as indexing): >>> l1 = [1, 2, 3, 4, 5, 6] >>> l2 = … Read more
The right answer (using Python 2.7 and later, since check_output() was introduced then) is: py2output = subprocess.check_output([‘python’,’py2.py’,’-i’, ‘test.txt’]) To demonstrate, here are my two programs: py2.py: import sys print sys.argv py3.py: import subprocess py2output = subprocess.check_output([‘python’, ‘py2.py’, ‘-i’, ‘test.txt’]) print(‘py2 said:’, py2output) Running it: $ python3 py3.py py2 said: b”[‘py2.py’, ‘-i’, ‘test.txt’]\n” Here’s what’s wrong … Read more
The crucial requirement on repr is that it should round-trip; that is, eval(repr(f)) == f should give True in all cases. In Python 2.x (before 2.7) repr works by doing a printf with format %.17g and discarding trailing zeroes. This is guaranteed correct (for 64-bit floats) by IEEE-754. Since 2.7 and 3.1, Python uses a … Read more
