In Python, you can overload constructors or methodsby defining multiple methods or constructors with the same name, but different parameters. When you call the method or constructor, Python will choose the correct one to execute based on the number and types of arguments passed in. For example...

Read our Understanding Recursive Functions in Python Guide to get started. 7. What are pointers, and how do they work? A pointer is a variable that stores the memory address of another variable as its value. Commonly used in data structures like linked lists, pointers allow low-level ...
In Python 2, the output of the above code will be: 5/2 = 2 5.0/2 = 2.5 5//2 = 2 5.0//2.0 = 2.0 By default, Python 2 automatically performs integer arithmetic if both operands are integers. As a result, 5/2 yields 2, while 5./2 yields 2.5. ...
4.What is the difference between a list and a tuple in Python? Both lists and tuples can store an ordered array of objects, however, a tuple is immutable. This means that once a tuple is created with objects in it, the objects can not be swapped out (mutating). A list still allows...
