Adding attributes to …An object in Python is an instance of a class, which groups together related properties and methods. Creating a class involves defining a class with its attributes and behaviors, and then, making an object is as simple as assigning a variable to the class name followed by parentheses.So I have the following code in which the value of a dictionary is an object, and the key to that object is an item in the object as such: def getName(self): return self.name. def getValue(self): return self.value. def __init__(self,name, value): self.name = name. self.value = value.Python Tuples. Python provides another type that is an ordered collection of objects, called a tuple. Pronunciation varies depending on whom you ask. Some pronounce it as though it were spelled “too-ple” (rhyming with “Mott the Hoople”), and others as though it were spelled “tup-ple” (rhyming with “supple”).Python, a versatile programming language known for its simplicity and readability, has gained immense popularity among beginners and seasoned developers alike.

There's also the builtin functions vars() and dir() which are different in subtle ways. And __slots__ can replace __dict__ in some unusual classes. Objects are complicated in Python.Object-oriented programming has some advantages over other design patterns. Development is faster and cheaper, with better software maintainability. This, in turn, leads to higher-quality software, which is also extensible with new methods and attributes. The learning curve is, however, steeper.
