Technology is a delicate and sensitive product, just like human skin. If something happens to technology, whether good or bad, it affects the entire system. And, in this ever-changing world, we must be more cautious in our use of technology. Nobody could have predicted in the 1980s that a programming language inspired by ABC (an abandoned programming language) would become one of the most popular languages of the twenty-first century. Python is now responsible for the vast majority of software applications used by people all over the world. Whether it’s machine learning, banking, scientific computing, video games, engineering, or any other imaginable field, chances are you’ll hear the term Python used by the majority of the developers working on the software. Everyone has used it or is using it, from Google, Facebook, Microsoft, NASA, IBM, and various small businesses. If you ask a programmer what the importance of a language is in programming, don’t be surprised if they say that a language is everything that goes into building a program and bringing what is imagined to life. Numerous languages are used for various purposes. However, some languages are universal and have a wide range of applications. Python is one such language that is widely understood and preferred for development all over the world. It is a general-purpose, high-level OOPs-based interpreted language widely used for dynamic applications worldwide. Python is extremely popular due to its versatility and breadth of application. The memory management in python is automatic as the Python developers creates a garbage collector so that the user does not have to do manual garbage collection.

Python is an open-source programming language. The Python company is one of the largest and is still free. Python does not require a subscription or a custom-built platform to be used, so it is compatible with any desktop or laptop computer. All of the tools required for Python coding, as well as the supporting means, modules, and libraries, are completely free. Because it is a free platform, it is accessible to all small and medium-sized businesses. Companies in their early stages can use the Python platform to launch their operations with low-cost software. The ability to quickly develop applications and software makes it suitable for startups, as they can survive in a cutthroat environment by leveraging the speed of the Python language. Many machine-learning applications are written in Python. Machine learning is a method of programming a machine to learn and solve a specific problem on its own. For example, product recommendations on websites such as Amazon, Flipkart, eBay, and others are based on a machine learning algorithm that recognizes the user’s interests. Another example of machine learning is face and voice recognition on your phone.
Memory Allocation in Python
Memory management is the process by which applications read and write data to and from memory. A memory manager decides where to store data from an application. Because memory is limited, like the pages in our book analogy, the manager must find some free space and make it available to the application. Memory allocation refers to the process of providing memory. Python memory management consists of a private heap containing all Python objects and data structures. The Python memory manager is in charge of managing this private heap. The Python memory manager is made up of various components that deal with various aspects of dynamic storage management, such as sharing, segmentation, preallocation, and caching. At the most basic level, a raw memory allocator ensures that there is enough space in the private heap for all Python-related data by interacting with the operating system’s memory manager. In addition to the raw memory allocator, several object-specific allocators operate on the same heap and implement distinct memory management policies tailored to the unique characteristics of each object type.
Memory allocation is a critical component of memory management for a developer. This process essentially allows free space in the computer’s virtual memory, and two types of virtual memory work while programs are being executed.
- Static Memory Allocation
- Dynamic Memory Allocation
Static Memory Allocation
Static memory allocation occurs during the compilation process. In C/C++, for example, we declare a static array with fixed sizes. Memory is allocated during compilation. However, we cannot reuse the memory in the following program.
- Stack Memory Allocation
Static memory is stored using the Stack data structure. It is only required within the specific function or method call. When we call the function, it is added to the program’s call stack. Variable assignment within the function temporarily stores the value in the function call stack; the function returns the value, and the call stack moves to the text task. All of these processes are handled by the compiler, so we don’t have to worry about them. The call stack (stack data structure) stores the program’s operational data, such as subroutines or function calls, in the order in which they will be called. When we call, these functions are retrieved from the stack.

Dynamic Memory Allocation
Unlike static memory allocation, dynamic memory allocates memory to the program at runtime. In C/C++, for example, there is a predefined size for the integer and float data types, but there is no predefined size for the data types. Objects are allocated memory at run time. Dynamic memory management is implemented via the Heap. The memory can be used throughout the program. Because everything in Python is an object, dynamic memory allocation motivates Python memory management. When an object is no longer in use, the Python memory manager disappears.
- Heap Memory Allocation
Heap data structures are used for dynamic memory and have nothing to do with naming counterparts. It is a type of memory that is used in the global space outside of the program. One of the most significant advantages of heap memory is that it frees up memory space when an object is no longer in use or a node is deleted. It is important to note that the name heap has nothing to do with the heap data structure. It is called a heap because it is a collection of memory space that programmers can allocate and de-allocate. Variables that are required outside of method or function calls or that are shared globally across multiple functions are stored in Heap memory.
Python Garbage Collection
Understanding Memory allocation is critical for any software developer because writing efficient code also means writing memory-efficient code. Memory allocation is the process of allocating a block of memory in a computer to a program. The memory allocation and deallocation methods in Python are automatic because the Python developers created a garbage collector for Python so that the user does not have to perform manual garbage collection. Garbage collection is the process by which the interpreter frees up memory when it is not in use so that it can be used by other objects. Assume that no reference points to an object in memory, indicating that it is not in use; therefore, the virtual machine has a garbage collector that automatically deletes that object from the heap memory.
Memory management is an essential component of computer work. Python handles almost everything behind the scenes, for better or worse. Python is a well-known computer language for a number of reasons. Python is recommended as a programming language for many industries.
