I struggled with this for a couple of hours this morning, but finally got it working! The problem is essentially that you can only include the twitter widgets.js script once in the page, and that script evaluates the data-text attribute on load. Therefore, in your example, you dynamically set the data-text attribute before loading the … Read more
The MetadataType attribute is used to specify help specify the additional information on the data object. To access the additional attributes you would need to do something like the following: using System; using System.Linq; using System.ComponentModel.DataAnnotations; using System.Reflection; namespace MetaDataTest { class Program { static void Main(string[] args) { MetadataTypeAttribute[] metadataTypes = typeof(MyTestClass).GetCustomAttributes(typeof(MetadataTypeAttribute), true).OfType<MetadataTypeAttribute>().ToArray(); MetadataTypeAttribute … Read more
For React v <= 15 console.log( ReactDOM.findDOMNode(this.refs.container).style); //React v > 0.14 console.log( React.findDOMNode(this.refs.container).style);//React v <= 0.13.3 EDIT: For getting the specific style value console.log(window.getComputedStyle(ReactDOM.findDOMNode(this.refs.container)).getPropertyValue(“border-radius”));// border-radius can be replaced with any other style attributes; For React v>= 16 assign ref using callback style or by using useRef/createRef. assignRef = element => { this.container = element; } … Read more
Why not just change it to int foo(int x, y) { if (y == 0) throwException(“Doh!”); return x/y; } This gives the same runtime results, and the compiler won’t complain.
All variables defined on the class level in Python are considered static class Example: Variable = 2 # static variable print Example.Variable # prints 2 (static variable) # Access through an instance instance = Example() print instance.Variable # still 2 (ordinary variable) # Change within an instance instance.Variable = 3 #(ordinary variable) print instance.Variable # … Read more
If you want the attribute to be shared by all instances of the class, use a class attribute: class A(object): foo = None This causes (‘foo’,None) to be a (key,value) pair in A.__dict__. If you want the attribute to be customizable on a per-instance basis, use an instance attribute: class A(object): def __init__(self): self.foo = … Read more
When writing the __init__ function for a class in python, you should always call the __init__ function of its superclass. We can use this to pass the relevant attributes directly to the superclass, so your code would look like this: class Person(object): def __init__(self, name, phone): self.name = name self.phone = phone class Teenager(Person): def … Read more
You could use functools.reduce: import functools def rsetattr(obj, attr, val): pre, _, post = attr.rpartition(‘.’) return setattr(rgetattr(obj, pre) if pre else obj, post, val) # using wonder’s beautiful simplification: https://stackoverflow.com/questions/31174295/getattr-and-setattr-on-nested-objects/31174427?noredirect=1#comment86638618_31174427 def rgetattr(obj, attr, *args): def _getattr(obj, attr): return getattr(obj, attr, *args) return functools.reduce(_getattr, [obj] + attr.split(‘.’)) rgetattr and rsetattr are drop-in replacements for getattr and … Read more
Aha! Found the answer here: cbar.ax.tick_params(labelsize=10) P.S. Upvote that answer and give Paul some love!
The dot operator is used for accessing attributes of any object. For example, a complex number >>> c = 3+4j has (among others) the two attributes real and imag: >>> c.real 3.0 >>> c.imag 4.0 As well as those, it has a method, conjugate(), which is also an attribute: >>> c.conjugate <built-in method conjugate of … Read more
