Instagram API Comments Created using Python (ERROR: AttributeError)
python,api,python-2.7,instagram,instagram-api
Unfortunately, Instagram is not very consistent in their API. The creation time of a media object is called created_time, but for a comment it is created_at. Also note there's no need to request the comments separately: they are already available for each media object, in media.comments....

Python: Terminate subprocess = Success, but it's still running (?)
Two processes are created because you call Popen with shell=True. It looks like the only reason you need to use a shell is so you make use of the file association with the interpreter. To resolve your issue you could also try: from subprocess Popen, PIPE, STDOUT pyTivoPath = "c:\pyTivo\pyTivo.py"...

random.randint not generating random values
You seem to be confused between defining a function and calling it and how parameters work. def blackjack(A,B): print "Welcome to Blackjack!" print "Your cards are",name[A-1],"&",name[B-1] total = value[A-1] + value[B-1] print "Your card total is",total In your function A and B are place holders.

What is the difference between <> and == in python?
The operator "<>" means 'not equal to', and the operator "==" means 'equal to'. The former evaluates to true if two things being compared are not equal, and the latter evaluates to true if two things being compared are equal. http://www.tutorialspoint.com/python/comparison_operators_example.htm...
Slicing a Python OrderedDict
python-2.7,slice,ordereddictionary
The ordered dict in the standard library, doesn't provide that functionality. Even though libraries existed for a few years before collections.OrderedDict that have this functionality (and provide essentially a superset of OrderedDict): voidspace odict and ruamel.ordereddict (I am the author of the latter package, which a reimplementation of odict in...
Python code not executing in order? MySQLdb UPDATE commits in unexpected order
python,python-2.7,threadpool,mysql-python
A finally clause is guaranteed to execute, even if the try clause raises an exception. What is probably happening here is that an exception is being raised, preventing the update from being committed, but the threads are triggered anyway. This doesn't really seen to be an appropriate use of try/finally....
Problems with tk entry and optionmenu widget in currency converter
My answer didn't satisfy me so I solved your problem. Changes: Added self keyword to currAmount1, currAmount2, and reflected this change everywhere in the script. (currAmount1 -> self.currAmount1) Called .get() on the Tkinter variables at the start of curr_search(): cur1 = self.curr_start1.get() cur2 = self.curr_start2.get() amount = self.currAmount1.get() Instead of...
Adding time/duration from CSV file
python,python-2.7,csv,datetime
Use datetime.timedelta() objects to model the durations, and pass in the 3 components as seconds, minutes and hours. Parse your file with the csv module; no point in re-inventing the character-separated-values-parsing wheel here. Use a dictionary to track In and Out values per user; using a collections.defaultdict() object will make...
PySerial client unable to write data
Obviously, /dev/tnt0 is not a serial device, or there is something wrong with that. Otherwise, your code looks valid.
Python root logger messages not being logged via handler configured with fileConfig
python,python-2.7,logging,configuration-files
A potential problem is that you are importing the module before you set up the logger configuration. That way, the module requests a logger before the logging is setup. Looking a fileConfig()'s documentation, the reason subsequent logging to the pre-obtained loggers fails is the default value for its disable_existing_loggers argument:...

How can I detect a URL really exists despite a 301 or 302 redirect?
Use the steps outlined in diveintopython (copied and slightly cleaned bellow) if you want to use stdlib only. Otherwise, use something more nuanced (like Mechanize) to follow redirects. class SmartRedirectHandler(urllib2.HTTPRedirectHandler): def http_error_301(self, req, fp, code, msg, headers): result = urllib2.HTTPRedirectHandler.http_error_301( self, req, fp, code, msg, headers) result.status = code return...
How to find Unused Security Groups of all AWS Security Groups?

How to find longest consistent increment in a python list?
One problem (but not the only one) with your code is that you are always adding the elements to the same possible_list, thus the lists in bigger_list are in fact all the same list! Instead, I suggest using [-1] to access the last element of the list of subsequences (i.e....
Simulating Fibonacci's Rabbits with multiple offsprings using python

Need workaround to treat float values as tuples when updating “list” of float values
python-2.7,matplotlib,computer-science,floating-point-conversion
You can't append to a tuple at all (tuples are immutable), and extending to a list with + requires another list. Make curveList a list by declaring it with: curveList = [] and use: curveList.append(curve) to add an element to the end of it. Or (less good because of the...
