For more on classes, try this link: http://en.wikibooks.org/wiki/A_Beginner%27s_Python_Tutorial/Classes.ou can use a generator! A generator is basically a function that keeps track of the state of its objects even after you leave the function and call it again. Instead of using 'return' and the end, you use 'yield'. Try something like this: if you call HealthScore(-5), it will return 95.

ctypes tutorial ctypes exports the byref function which is used to pass parameters by reference. The same effect can be achieved with the pointer function, although pointer does a lot more work since it constructs a real pointer object, so it is faster to use byref if you don't need the pointer object in Python itself:

Python Course Using a 'return' in a Generator. Since Python 3.3, generators can also use return statements, but a generator still needs at least one yield statement to be a generator! A return statement inside of a generator is equivalent to raise StopIteration() Let's have a look at a generator in which we raise StopIteration:

DRA: Differential Reinforcement of Alternative Behavior DRA, or Differential Reinforcement of Alternative Behavior, is an ABA technique used to reduce problem behaviors. ABA professionals always seek to accomplish behavior reduction through ethical, reinforcement based methods first. In other words we don’t just seek to make a problem behavior stop.

Repressor In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes into messenger RNA. An RNA-binding repressor binds to the mRNA and prevents translation of the mRNA into protein. This blocking of expression is called repression.

In Python, what is NumPy? How is it used? NumPy is open source Python package for scientific computing. NumPy supports large, multidimensional arrays and matrices. NumPy is written in Python and C. NumPy arrays are faster than Python lists. But NumPy arrays are not flexible like Python lists, you can store only same data type in each column. NumPy is essential for other Python scientific packages like SciPy, scikit-learn and OpenCV.

5. The import system Â¶ Python includes a number of default finders and importers. The first one knows how to locate built-in modules, and the second knows how to locate frozen modules. A third default finder searches an import path for modules. The import path is a list of locations that may name file system paths or zip files.

Review: LWRC REPR The LWRC International REPR (Rapid Engagement Precision Rifle) comes to us from requests by our war fighters. 1  LWRC's REPR or Rapid Engagement Precision Rifle was born of requests from troops for an accurate, more powerful semiauto. Specifically, when our armed forces members are whacking IED insertion teams, they need more shots, faster than what a bolt-action rifle can deliver.

- This is necroposting but for the sake of future readers, \w is the python equivalent of the class: [^a-zA-Z0-9_]. As you can see here , at least for Python 2.7.x to 3.4.y, * does not enter into that. If it did the regex class [\w*] would introduce a useless repetition of * as a literal caracter (i.e. w/ no special meaning because it is included inside the square brackets denoting a class.). – Cbhihe Feb 2 '16 at 16:06
