I have tried to use Python's ConfigParser module to save settings. For my app it's important that I preserve the case of each name in my sections. The docs mention that passing str() to ConfigParser.optionxform() would accomplish this, but it doesn't work for me. The names are all lowercase. Am I missing something? <~/.myrc contents> [rules] Monkey = foo Ferret = baz Python pseudocode of what I get: import ConfigParser,os def get_config(): config = ConfigParser.ConfigParser() config.optionxform(str()) try: config.read(os.path.expanduser('~/.myrc')) return config except Exception, e: log.error

I have a generator function like the following: def myfunct(): ... yield result The usual way to call this function would be: for r in myfunct(): dostuff(r) My question, is there a way to get just one element from the generator whenever I like? For example, I'd like to do something like: while True: ... if something: my_element = pick_just_one_element(myfunct()) dostuff(my_element) ... Create a generator using g = myfunct() Everytime you would like an item, use next(g) (or g.next() in Python 2.5 or below). If the generator exits, it will raise StopIteration . You can either catch this

I have the following code inside a function: stored_blocks = {} def replace_blocks(m): block = m.group(0) block_hash = sha1(block) stored_blocks[block_hash] = block return '{{{%s}}}' % block_hash num_converted = 0 def convert_variables(m): name = m.group(1) num_converted += 1 return '<%%= %s %%>' % name fixed = MATCH_DECLARE_NEW.sub('', template) fixed = MATCH_PYTHON_BLOCK.sub(replace_blocks, fixed) fixed = MATCH_FORMAT.sub(convert_variables, fixed) Adding elements to stored_blocks works fine, but I cannot increase num_converted in the second subfunction: UnboundLocalError: local variable 'num

Possible Duplicate: How do I treat an ASCII string as unicode and unescape the escaped characters in it in python? How do convert unicode escape sequences to unicode characters in a python string I have a string that contains unicode characters e.g. \u2026 etc. Somehow it is not received to me as unicode , but is received as a str . How do I convert it back to unicode? >>> a="Hello\u2026" >>> b=u"Hello\u2026" >>> print a Hello\u2026 >>> print b Hello… >>> print unicode(a) Hello\u2026 >>> So clearly unicode(a) is not the answer. Then what is? Unicode escapes only work in unicode strings, so

I'm trying to use the example code from here: http://www.pymssql.org/en/latest/pymssql_examples.html I installed the pymmsql module using pip . I also see it in the site-packages folder C:\Python27\Lib\site-packages\pymmsql.pyd But, when I execute the code, I get the following error: Traceback (most recent call last): File "C:\Android\android_workspace\pythonProject\test.py", line 2, in <module> import pymssql ImportError: DLL load failed: The specified module could not be found. What am I missing? Update Due to negative feedback from the user community regarding the 2.1.2 change, pymssql 2.1

I've a strange issue in Python: the division is not performed correctly: print pointB[1] print pointA[1] print pointB[0] print pointA[0] print (pointB[1]-pointA[1]) / (pointB[0]-pointA[0]) These are the results: 100 50 100 40 0 thanks user225312 The above behavior is true for Python 2. The behavior of / was fixed in Python 3. In Python 2 you can use: from __future__ import division and then use / to get the result you desire. >>> 5 / 2 2 >>> from __future__ import division >>> 5 / 2 2.5 Since you are dividing two integers, you get the result as an integer. Or, change one of the numbers to a
