In this tutorial, you learned what lazy evaluation in Python is and how it’s different from eager evaluation. Some expressions aren’t evaluated when the program first encounters them. Instead, they’re evaluated when the values are needed in the program. This type of evaluation is referred ...
PEP 492 introduced support for native coroutines and async / await syntax to Python 3.5. A notable limitation of the Python 3.5 implementation is that it was not possible to use await and yield in the same function body. In Python 3.6 this restriction has been lifted, making it possible to...
in the same line, the Python interpreter creates a new object, then references the second variable at the same time. If you do it on separate lines, it doesn't "know" that there's already "wtf!" as an object (because "wtf!" is not implicitly interned as per the facts mentioned abov...
This is another way to implement a queue in Python. We need to import deque from the collections module. Operations involved append()− This function adds an element at the end of the queue. popleft()− This function removes and returns the first element in the queue in O(1) time co...
Pythonic code—when you first hear of it, you might think it is a programming paradigm, similar to object-oriented or functional programming. While some of it could be considered as such, it is actually more of a design philosophy. Python leaves you free to choose to program in an object...
