Also, if no argument is passed to defaultdict, it also works the same as a dictionary. Question 2: Can we avoid getting a KeyError in a dict without using defaultdict? Answer: Yes. Using mutable collections like
In Python, thecloserfunction is not a built-in feature of the language itself. However, in programming, "closures" refer to a powerful concept where a function retains access to the variables from its enclosing scope even after the scope has finished executing. This allows for a form of data...
In Python programming, the “assert” statement stands as a flag for code correctness, a vigilant guardian against errors that may lurk within your scripts.”assert” is a Python keyword that evaluates a specified condition, ensuring that it holds true as your program runs. When the condition i...

Creating Python Inner Functions A function defined inside another function is known as an inner function or a nested function. In Python, this kind of function can access names in the enclosing function. Here’s an example of how to create an inner function in Python: Python >>> def outer...
In simplest terms, a Python list is most suitable for data storage and not ideally intended for math tasks, while a NumPy list can easily support math-intensive tasks. Python provides a basicdata structurecalled alist. A Python list supports a changeable -- or mutable -- ordered sequence of...
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 ...
Tuples in Python Python Function – Example & Syntax What is Regular Expression in Python Python Modules, Regular Expressions & Python Frameworks How to Sort a List in Python Without Using Sort Function How to Compare Two Strings in Python?
This feature makes tuples an excellent choice for storing data that should not be changed once it’s been set. Tuples are similar to lists in many ways. The main difference between them is that tuples are immutable, while lists are mutable. This means that you can add, remove, or ...
In Python, there are two types of objects:Immutable objects can’t be changed. Mutable objects can be changed.Understanding this difference is the first key to navigating the landscape of pointers in Python. Here’s a breakdown of common types and whether or not they are mutable or immutable...
