Flask needs to know that this class is an endpoint for our API, and so we pass Resource in with the class definition. Inside the class, we include our HTTP methods (GET, POST, DELETE, etc.). Finally, we link our Users class with the /users endpoint using api.add_resource. Because w...

ClassDef A class statement. Note that ClassDef extends Assign as a class definition binds the newly created classClassExpr An (artificial) expression corresponding to a class definition. It is recommended to use ClassDef instead.ClassExpr_ INTERNAL: See the class ClassExpr for further information....
However, the NumPy solve function has no optional parameters. Next, the demo program shows an example of the Python try-except mechanism: XML Copy try: A = np.array([[2.0, 4.0], [3.0, 6.0]]) Ai = spla.inv(A) print Ai except Exception, e: print "Fatal ...

So far, so good. If you want the function to take parameters, you include one or more names inside the parentheses of the function definition. Any value to be returned is given using the ubiquitous “return” keyword: XML复制 def theKnightsWhoSayNi(gift): if gift == "shrubbery": r...
