python-2.7

问题 I am just trying to add background colors as gradient colors! This may look my Tkinter-GUI more attractive than common color codes. Is there any way to achieve this in python, can anyone please help me Can it incorporate something like this? bg="40%,#207cca 40%,#2989d8 50%" def createwidgets(self): master_f = Tkinter.Frame (objMG.root, relief='sunken', bd=2,height =10,bg='#54596d') master_f.pack (side='top', fill='both', expand=1) self.Up_frame = Tkinter.Frame(master_f,relief='sunken',height

问题 I know there are a ton of how-to import Python modules not in path, but I have yet to come across using Python's __init.py__ vs sys.path.insert. Which method is better? Are there any obvious drawbacks to either, like performance? Is one more "Pythonic?" One scenario I can think of, is I have a program that users download and put in whatever directory, so I don't know the absolute path (unless I get it programatically). The folder structure is working dir __init__.py foo.py src/ my_utils.py _

问题 I'm looking to make a fan chart type line plot in Python which resembles the Bank of England Interest Rate fan charts like this one: I'm quite well practiced with using matplotlib for standard line/bar/scatter plots, however this seems like it would require something of a more custom implementation. I've Google'd about and cannot seem to find any standard libraries for Python that do this sort of thing at all or even any code that describes how this might be done. Any help on how this could

问题 I've got two separate functions. Each of them takes quite a long time to execute. def function1(arg): do_some_stuff_here return result1 def function2(arg1, arg2, arg3): do_some_stuff_here return result2 I'd like to launch them in parallel, get their results (knowing which is which) and process the results afterwards. For what I've understood, multiprocessing is more efficient than Threading in Python 2.7 (GIL related issue). However I'm a bit lost whether it is better to use Process, Pool or

问题 I am trying to get whether a word is in singular form or in plural form by using nltk pos_tag. But the results are not accurate. So, I need a way to find how can get whether a word is in singular form or in plural form? moreover I need it without using any python package. 回答1: For English, every word should somehow have a root lemma where the default plurality is singular. Assuming that you have only nouns in your list, you can try this: from nltk.stem import WordNetLemmatizer wnl =
