attributes

问题 Firstly, apologies for how obvious these two questions seem to be; I'm very very new to this and don't have a clue what I'm doing. I'm trying to write something to apply the Scipy function for spline interpolation to an array of values. My code currently looks like this: import numpy as np import scipy as sp from scipy.interpolate import interp1d x=var x1 = ([0.1,0.3,0.4]) y1 = [0.2,0.5,0.6] new_length = 25 new_x = np.linspace(x.min(), x.max(), new_length) new_y = sp.interpolate.interp1d(x, y

问题 How can I get all tbody > tr that doesn't have this style attribute: display: none ? 回答1: $("tbody > tr:visible") Should do it, by using the :visible selector. 回答2: The accepted answer works, and is very useful, but not technically what the OP directly asked. I'm splitting hairs, admittedly, but I needed to find only tr elements which literally did not contain display: none within their style attribute, because the parent element might be hidden, thus returning no elements. So I wrote the

问题 I am using Foolproof library in ASP.Net MVC project and in some cases I need to check a property within a member class of my model using attribues . For example I have a user class which has a property of type Address and I need to check for the City in the Address. The attributes need to have the name of the property in a dot notation for my example you could say "Address.City". Of course this suffers from refactoring issues if I need to change either names later on (Address or City) I need

问题 This question already has answers here : Tkinter: AttributeError: NoneType object has no attribute <attribute name> (3 answers) Closed 11 months ago . I recently started coding in python 3.6 with tkinter and tried creating my own project on repl.it . The project is a simple interactive to-do list, however I am stuck and cant get the function to work. The function is just simply getting the entry and adding it to a list box, but when I try adding the function it returns 'NoneType' object has
