In the above snippet, my_decorator is a function taking in an argument func. Inside the decorator function, we define another function wrapper which wraps the behavior we want to add before and after calling func. Then, it returns wrapper function. When we pass say_hello function to my_deco...
Called by built-in functionhash()and for operations on members of hashed collections includingset,frozenset, anddict.__hash__()should return an integer. The only required property is that objects which compare equal have the same hash value; it is advised to somehow mix together (e.g. using...
Keras is high-level API wrapper for the low-level API, capable of running on top of TensorFlow, CNTK, or Theano. Keras High-Level API handles the way we make models, defining layers, or set up multiple input-output models. In this level, Keras also compiles our model with loss and op...
Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of ...
if something is true then execute this piece of code otherwise do something else - this kind of “if-else” construction would usually require the use of parentheses along with other symbols like “>” and “<” operators. another common application involves function calls in some programming ...
As you can see, the asterisk operator basically removes the wrapper data type (i.e., thelist). Here is how you can use simple unpacking when calling a function with positional arguments: defsay_hello(*args): forarginargs: print("hello "+ arg) ...

To avoid using the data field in the comparison, enclose thePriorityQueueclass in a wrapper and override its default behavior. Consult thePython PriorityQueue class documentationfor more details about this technique. Python’s implementation of the PriorityQueue class extends the Pythonheapqmodule, which...
