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...
Socket programming in Python combines network communication and Python knowledge to build programs that can connect over networks. To help you understand how computer programs chat with each other over the internet, we will discuss the various aspects of socket programming in this post. So, if you...
The concept of args and kwargs is a common use case found in function arguments in Python. They allow an arbitrary number of arguments and keyword arguments to functions. *args¶ Using*argsallows to pass an arbitrary number of function arguments. Inside the function*argswill give you all fu...
We use the print() function to show that the arguments passed to the function,args, are packed into one tuple. And since the extend() list method can take any iterable object to extend the list, we can pass in that tuple. No matter what number of positional arguments we pass in when ...
Last week, while working on a support case, our customer was facing performance issues in their Python application. After some investigation, I decided to...
show_args('Hello','World','Python') Output: Hello World Python **kwargs: Used when not sure the number of keyword arguments to be passed to a function. e.g. to pass the values of adictionaryas keyword arguments defshow_kwargs(**kwargs):forkey, valueinkwargs.items():print(f"{key...

What does ** and * do for python parameters? The *args and **kwargs ist a common idiom to allow arbitrary number of arguments to functions as described in the section more on defining functions in the the python documentation. The *args will give you all funtion parameters a a list:...
By default, Python still uses timestamp-based invalidation and does not generate hash-based .pyc files at runtime. Hash-based .pyc files may be generated with py_compile or compileall. Hash-based .pyc files come in two variants: checked and unchecked. Python validates checked hash-based ....
In this step-by-step tutorial, you'll get a clearer understanding of Python's object model and learn why pointers don't really exist in Python. You'll also cover ways to simulate pointers in Python without the memory-management nightmare.
