Using the builtin ctypes module, you can create real C-style pointers in Python. If you are unfamiliar with ctypes, then you can take a look at Extending Python With C Libraries and the “ctypes” Module. The real reason you would use this is if you needed to make a function call to a C library that requires a pointer.

The assignment operator = in Python automatically creates and assigns a pointer to the variable. Example: l = [1,2,3,4] The above statement creates a list object and points a pointer to it called “l”. If you assign the same list object both to two different variables m and l, they will point to the same memory location. #Assign.
Jun 24, 2010 · This means that a pointer does not change even if the pointed variable is changed, directly or indirectly (for example by a pointer) Indeed you can't just make a fully working pointer in one line of code, but after some research it turned out not to be that extremely difficult.
Aug 18, 2023 · Python’s absence of pointers roots in its high-level, interpreted architecture divergent from low-level, compiled languages. Python’s utilization of object references, combined with its ...
But Python has no inverse operation: there’s no get_value_via_pointer() that can get you myvar given mypointer. So Python doesn’t have the classic pair of operations to be able to work with pointers explicitly. But on the other hand, every variable in Python is a pointer, because variables in Python are names that refer to objects.
Final Thoughts. So there you have it – Python doesn’t use pointers because pointers are a tool that can be used by programmers in other languages to properly allocate memory, and since Python does this process automatically there is no need to use pointers. We hope that this article has given you a foundation to understand what exactly ...

When we create a variable or an object in a programming language, we save it to a specific CPU address. When we output the data, it is drawn from that address. Pointers are used to store addresses and manage memory. Python does not have a concept of pointers. Python does not support pointers.
