问题 I have fired up a WSGI application using Spyne for some SOAP services that I'm trying to build. I'm absolutely new to SOAP and Spyne in general and I can't seem to figure out how to return a JSON/Python dict as XML. This is what I've done. class Fruits(ServiceBase): @rpc(_returns=Iterable(Unicode)) def fruitify(self): fruits = {"apple" : "1", "orange" : ["2","3","4"]} return fruits I think the problem lies in the decorator I'm specifying using _returns . I tried reading the docs again and

问题 I want to get the data of json folders using Python 3.7.2. This is my json file: {"device": [ {"name": "device1", "status": 0}, {"name": "device2", "status": 1}, {"name": "device2", "status": 1} ] } For my project I need following variables: variable of all devices gathered in a list: devices = ["device1", "device1", "device1"] status of devices saved in different variables: status_device1 = 0 status_device2 = 1 status_device3 = 1 It is possible to change the structure of the json file, but

问题 I have a list made of lists, to create a matrix, mostly filled with zeros and some other numbers like this a = [[0,0,0,1,0,0,0,0], [3,0,0,2,1,0,0,0], [3,0,0,0,0,1,0,0], [3,5,0,4,0,0,0,0]] how could I make a function that takes that variable, and find if there is a number repeated 3 times in the diagonals? For example that It returns True because of the 1. I tried to implement a function like this: def find_diagonal(matriz): for x in range(len(matrix)): for for a in range(len(x)): if matriz[x]

问题 I'm facing a KeyError I can't explain or understand. I have a notebook, in which I define a variable PREFIX in a cell: PREFIX = "/home/mavax/Documents/info/notebook/log_study" which is simply a path to a folder containing logs, so people using the notebook just need to change the path if they want to execute the code below. Then, later (quite a bunch of cells beneath), I use it, without any problem: for basename in ["log_converted_full.txt", "log_converted_trimmed.txt"]: entries = load_log

问题 This probably an easy question but I just can't seem to make it work consistently for different permutations. What is the Python3 equivalent of this? print >> sys.stdout, "Generated file: %s in directory %s\n" % (name+".wav", outdir) I've tried print("String to print %s %s\n", file=sys.stdout % (var1, var2)) and print("String to print {} {}\n".format(var1, var2), file=sys.stdout) What is the best way to do this in Python3 now that the >> operator is no more. I know the % () has the be within

问题 I'm trying to understand the performance of list comprehensions in Python, and the trade-offs of using them versus for loops to create lists. One of the known performance costs of using a for loop to append elements to a list is that at each iteration it is O(k) (where k is the length of the list) because the append needs to get to the end of the list to add an additional element. How does this work for list comprehensions? At each iteration does it need to get to the end of the new list to

问题 I'm installing my module with pip. The following is the setup.py: from setuptools import setup, find_packages with open('requirements.txt') as f: required = f.read().splitlines() print(required) setup( name='glm_plotter', packages=find_packages(), include_package_data=True, install_requires=required ) and MANIFEST.in: recursive-include glm_plotter/templates * recursive-include glm_plotter/static * When installing, the directories and files seem to get installed: ... creating build/lib/glm

问题 I want to design my own HTML template with tags like JSP or Jade and then pass data from python to it and let it generate full html page. I don't want to construct document at python side like with DOM. Only data goes to page and page tempalte decides, how data lays out. I don't want to serve resulting pages with HTTP, only generate HTML files. Is it possible? UPDATE I found Jinja2, but I has strange boilerplate requirements. For example, they want me to create environment with env =

问题 So I have a Label where when a button is pressed, it changes the name of the text to display another label below the existing label. It pretty much just prints the same label with a different text on the row below. When the Delete Text button is pressed, it will delete the new label that has been created but how do I delete the label before the new label? I can also only remove the label via destroy and not forget. I tried changing the text of the variable back to what it says on the window
