Deleting Collection Items in Python Python’s collection classes provide different methods for removing one or more items from a collection object. remove() Method The remove() method removes the given item from a collection, if it exists. However, if the item…
Python Literals In computer science, a literal is a symbolic representation of a fixed value in source code. For example, in an assignment statement. x = 10 Here, 10 is a literal value, meaning that 10 is stored directly in…
Waiting on Python Threads The join() method in the Thread class blocks the calling thread until the thread calling join() terminates. Termination can occur normally, due to an unhandled exception, or until an optional timeout occurs. It can be called…
Modifying Dictionary Items in Python In addition to using dictionary literals, we can create dictionary objects by using comma-separated key-value pairs within curly braces. We can also use the built-in dict() function to create dictionary objects. Empty Dictionary Using the…
Python Encapsulation The principle of encapsulation is one of the main pillars of the object-oriented programming paradigm. Python takes a different approach to implementing encapsulation. As we know, a class is a user-defined object prototype. It defines a set of…
Python URL Handling On the internet, resources are identified by URLs (Uniform Resource Locators). The urllib package, bundled with Python’s standard library, provides utilities for working with URLs. It includes the following modules: The urllib.parse module parses URLs into their…
Python Collection Loops In Python, collections are neither sequences nor mappings. Therefore, objects in a collection cannot be iterated over using their index or key. However, you can use a for loop to iterate over each item in a collection.…
Python Thread Deadlock Deadlock can be described as a concurrency failure mode. It is a situation in a program where one or more threads wait for a condition that never occurs. As a result, the threads cannot continue executing, the…
Python Recursion A function that calls itself is called a recursive function. This approach is useful when a problem defines itself. Although this involves iteration, solving such problems using iterative methods can be tedious. Recursion provides a very concise way…
Python Access Modifiers Languages like C++ and Java use access modifiers to restrict access to class members (i.e., variables and methods). These languages have the public, protected, and private keywords to specify access types. A class member is said to…
