which one is the right definition of data-descriptor and non-data descriptor?
The second quote is correct. The second quote comes from the Python language reference (though you've provided the wrong link), and the language reference is considered more authoritative than how-to guides. The language reference also explains why Set doesn't override the instance dict for a.b: If it does not define...
How do you plot a graph consisting of extracted entries from a nested list?
plot,list-comprehension,python-3.4,nested-lists
You need to build two new lists. You can do this with list comprehensions: x = [sub[0] for sub in nested_list] y = [sub[2] for sub in nested_list] plt.plot(x,y) Your code tried to access one level of nesting too many (you can only address nested_list[k][0], not nested_list[k][0][0]) or tried to...
Loop through downloading files using selenium in Python
python,selenium,selenium-webdriver,web-scraping,python-3.4
You need to pass the filename into the XPath expression: filename = driver.find_element_by_xpath('//a[contains(text(), "{filename}")]'.format(filename=f)) Though, an easier location technique here would be "by partial link text": for f in fname: filename = driver.find_element_by_partial_link_text(f) filename.click() ...
does the order when defining functions in classes in python matter
python,function,class,python-3.4
The order of class attributes does not matter except in specific cases (e.g. properties when using decorator notation for the accessors). The class object itself will be instantiated once the class block has exited.
Drawing pentagon,hexagon in Pygame

NetworkX Graph object not subscriptable
python,python-3.x,python-3.4,networkx
Analysis of your current approach You are using subscript notation via the square brackets. Normally, you would type my_object[key], which is translated as a first approximation* into my_object.__getitem__(key). In particular, if the type(my_object) does not define the __getitem__ attribute, then you effectively get an error that says that type(my_object) is...

Why is this Python 3 asyncio client sending the bytes only after the Python process is interrupted?
python,client-server,python-3.4,python-asyncio
The problem is likely that you're calling reader.read() on the server-side (and also on the client-side), which will block until an EOF is sent from the server. But presumably you're not doing that - you're just sending some bytes over and keeping the connection open. Instead, you need either to...

Content-Length should be specified for iterable data of type class 'dict'
urllib.request does not support passing in unencoded dictionaries; if you are sending JSON data you need to encode that dictionary to JSON yourself: import json json_data = json.dumps(payload).encode('utf8') request = urllib.request.Request(url, data=payload, method='PUT', headers={'Content-Type': 'application/json'}) You may want to look at installing the requests library; it supports encoding JSON for...
multiprocessing.Pool.imap_unordered with fixed queue size or buffer?

Since processing is fast, but writing is slow, it sounds like your problem is I/O-bound. Therefore there might not be much to be gained from using multiprocessing. However, it is possible to peel off chunks of data, process the chunk, and wait until that data has been written before peeling...
Response Time Accuracy

What's the correct way to clean up after an interrupted event loop?

When you CTRL+C, the event loop gets stopped, so your calls to t.cancel() don't actually take effect. For the tasks to be cancelled, you need to start the loop back up again. Here's how you can handle it: import asyncio @asyncio.coroutine def shleepy_time(seconds): print("Shleeping for {s} seconds...".format(s=seconds)) yield from asyncio.sleep(seconds)...

The path of managed.py looks unusual to me. managed.py is usually at the top level project directory.

The simplest solution is to make string global: def printtext(): global e global string string = e.get() text.insert(INSERT, string) When you do that, other parts of your code can now access the value in string. This isn't the best solution, because excessive use of global variables makes a program hard...
How can I read a reg_qword in winreg in python 3.4?

The code you wrote interprets the value as a big-endian-stored integer. However, REG_QWORD is stored as a little-endian number. There's a much easier way to convert the bytes value of a 64-bit integer: using struct.unpack(). The format '<q' will read a signed 64-bit little-endian integer: >>> struct.unpack('<q', b'\x10\xba\xef\xa7S\x12\x00\x00') (20150509091344,) And...
