Python Thread Lifecycle A thread object goes through different stages. When a new thread object is created, it must be started. This calls the run() method of the thread class. This method contains the logic for the process to be…
Python GUI Interface In this chapter, you’ll learn about some popular Python integrated development environments (IDEs) and how to use them to develop programs. To use Python’s scripting mode, you need to save a sequence of Python instructions in a…
Python Exception Handling If you have code that might raise an exception, you can protect your program by enclosing it in a try block. After the try block, include an except statement, followed by code to handle the problem as…
Concatenating Lists in Python In Python, a list is classified as a sequence-type object. It is a collection of items of different data types, each with a zero-based index. You can use different methods to concatenate two Python lists. All…
Python Set Methods The following methods are defined in the Python set class: Number Method and Description 1 add() Adds an element to a set. 2 clear() Removes all elements from a set. 3 copy() Returns a shallow copy of…
Python Features Python is a feature-rich, high-level, interpreted, interactive, and object-oriented scripting language. This tutorial will list some of Python’s key features: Python Features Let’s highlight some of the key features that make Python so popular. In addition to these…
Python try-finally block You can use a finally block after a try block. In the finally block, you can place any code that must execute regardless of whether the try block raises an exception. The syntax of the try-finally statement…
Python Polymorphism The term “polymorphism” refers to a function or method that takes on different forms in different contexts. Because Python is a dynamically typed language, implementing polymorphism is very easy. If a method in a parent class is overridden…
Python Method Overloading Method overloading is a key feature of object-oriented programming. Java, C++, and C# all support method overloading, but Python doesn’t. Method overloading occurs when a method with the same name is defined more than once in a…
Python Tuple Loops You can use Python’s for loop construct to iterate over the items in a tuple. Iteration can be accomplished by using the tuple as an iterator or by using an index. Syntax Python tuples provide an iterator…
