Just because pointers in Python don’t exist natively doesn’t mean you can’t get the benefits of using pointers. In fact, there are multiple ways to simulate pointers in Python. You’ll learn two in this section: Using mutable types as pointers; Using custom Python objects; Okay, let’s get to the point. Using Mutable Types as Pointers

Jun 24, 2010 · There is only a single type of variable assignment in Python. What your example actually demonstrates is that dicts are mutable while ints are immutable. When you do dict2 = dict1, both variables now refer to the same address in memory, which you can confirm with the id() function. And the exact same is true for the int example b = a.
Does Python have Pointers? Sadly, Python doesn’t have pointers like other languages for explicit use but is implemented under the hood. Types such as list, dictionary, class, and objects, etc in Python behave like pointers under the hood. The assignment operator = in Python automatically creates and assigns a pointer to the variable. Example:
Jun 13, 2020 · Though the concept of pointers is alien to Python, the same objective can be met with the help of objects. Before we discuss further on this, let us first understand the role of objects in Python. What are Objects? Everything is an object in Python. If you are just getting started with Python, use any REPL and explore the isinstance() method to ...
They allow you to create great efficiency in parts of your code but can lead to various memory management bugs. You’ll learn about Python’s object model and see why pointers in Python don’t really exist. For the cases where you need to mimic pointer behavior, you’ll learn ways to simulate pointers in Python without managing memory.
This is the closest equivalent in Python to a memory address in languages with explicit pointers. Remember, Python handles memory management automatically, so you don’t need to worry about explicit memory addresses or pointer arithmetic as you would in languages like C or Go.

Sep 10, 2024 · Assignment: When you assign a value to a variable in Python, you are creating an association between a name and an object. For example, when you write x = 1000, Python creates an integer object 1000 and x points to it. Reassignment: If you assign a new value to a variable, the name is simply attached to the new object. For instance, if later in ...
