Docstrings are a type of documentation in Python that describe what a function, class, or module does, and how it should be used. They are written as strings at the beginning of the code block, immediately following the declaration of the function, cla There are several docstring formats that are commonly used in Python. Some of the most popular formats include: "Don't repeat yourself" (DRY) is a software development principle that advocates for reducing repetition and redundancy in code. The idea is that if you have duplicate code or logic in your program, you increase the risk of errors and make it harder to maintain and update your code. In programming, "pass by assignment" (also called "call by object reference" or "call by sharing") is a way In Python, objects can be either mutable or immutable. An object is considered immutable if its state cannot be modified after it is created. For example, Context managers are a useful feature in Python that allow you to manage resources, such as files or network connections, in a safe and ef The In Python, a nested context is when one or more context managers are used inside another context manager. This allows you to manage multip There are two main ways to define a context manager in Python: In Python, errors can be handled using the In Python, functions are first-class objects, which means they can be treated like any other object, such as an integer, string, or list. In Python, functions are treated as first-class objects, which means they can be assigned to variables just like any other object. This al In Python, functions are first-class objects, which means they can be stored in lists and dictionaries just like any other object. This al In Python, you can reference a function by using its name without parentheses. This is useful when you want to pass a function as an argument to another function, or when you want to assign a function to a variable. Functions as arguments
In Python, functions can be passed as arguments to other functions. This is known as higher-order functions, and it allows for a powerful and flexible programming paradigm. Here's an example:
