20 Differences Between C++ and Python

Python and C++ are among the most popular programming languages. Both support Object-Oriented Programming (OOP). While they share some similarities, they also have significant differences, making them suitable for different types of projects. For instance, if you're programming a microcontroller, you will likely need to use C or C++. However, if you're developing a web application, Python is the ideal choice. So, what are their commonalities and distinguishing features?

What is C++?

C++ is a general-purpose programming language introduced in 1979. Initially, it was introduced as an extension of the C language and was therefore called "C with Classes." C++ is used for developing software for various applications. It is considered a mid-level programming language as it incorporates both high-level and low-level programming features. It is highly efficient in game development, code optimization, mathematical computations, and numerical analysis projects.

Features of C++:

• It is a portable language, meaning you can use the same code across different environments.
• It is a fast and efficient language.
• It allows dynamic memory allocation.
• Unlike C, C++ is object-oriented.
• It is relatively easy to install.

Applications of C++:

• C++ is used in game development, especially for handling the complexity of 3D games and multi-layer networking features.
• It is used to develop compilers for programming languages since it is considered closer to hardware.
• It plays an important role in software development. Many advanced applications are built with C++. Examples include parts of Adobe, Spotify, and YouTube.
• It is also used in creating embedded systems. Because of its proximity to hardware, it is used in producing smartwatches, medical devices, and IoT devices.

What is Python?

Python is a high-level, object-oriented programming language introduced by Guido van Rossum in 1991. It is one of the simplest programming languages to learn. Python is widely used in machine learning, data analysis, and statistics. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. It also features dynamic typing and binding.

Features of Python:

• It is a platform-independent, open-source language. You can run the same code on different platforms.
• It is object-oriented and offers features like dynamic type checking and high readability.
• Its structure and object-oriented approach help in writing clear and logical code for various projects.
• It supports automatic garbage collection, debugging, and testing modes.
• It has a vast standard library, reducing the need to write code for every task. This library also facilitates the implementation of various programs and algorithms.

Applications of Python:

• It is widely used in modern technologies such as artificial intelligence and machine learning.
• Due to its extensive library support, it is suitable for developing machine learning models.
• It is used in web development and supports multiple frameworks that simplify tasks.
• It serves as a supporting language in software development. For example, Dropbox used Python to develop its desktop application.
• Python is commonly used in robotics.

After learning about their features and basic characteristics, you might wonder, "C++ or Python?" Your choice should be based on the nature of your project. For example, while Python is a good choice for web development, C++ is rarely used in this area. Python also leads in data analysis, machine learning, and robotics. While C++ can be used for machine learning, it is not a common choice.

20 Differences Between C++ and Python

The main differences between C++ and Python are related to performance and ease of use. These factors influence your decision on which language to use for your next project. C++ is faster but harder to learn than Python, while Python is easier to understand and has a broader supporting library. Some programmers take a modular approach that combines the strengths of both languages. Although they are not directly compatible, they can work together. Here are the key differences between the two languages:

• Lines of Code: C++ requires more lines of code, making programming more time-consuming. Python allows you to accomplish more with fewer lines of code.
• File Extensions: C++ files have a .cpp extension, while Python files use .py. Python code does not need to be compiled; it can be directly interpreted and executed.
• Syntax: C++ has a complex syntax, whereas Python has a simple, human-readable structure.
• Implementation: Python can be implemented in CPython, Jython, PyPy, and IronPython, while C++ can be used in Turbo C++, Microsoft Visual C++, and Intel C++.
• Pointers: C++ supports pointers, while Python does not.
• Garbage Collection: C++ does not perform automatic garbage collection, requiring manual memory management. Python automatically manages memory.
• Memory Management: In C++, memory is managed using delete operators, whereas Python uses reference counting for automatic memory management.
• Nature of the Language: C++ is statically typed, meaning variable declarations are checked at compile time. Python is dynamically typed, increasing the risk of runtime errors.
• Functions: Python functions have no restrictions on parameter types and return values, while C++ enforces strict type matching.
• Types: C++ types are checked at compile time, reducing errors. Python types are checked at runtime, increasing the risk of errors.
• Code Maintenance: Python’s high readability and fewer lines of code make maintenance easier. C++’s complex syntax and longer code can be harder to maintain.
• Variable Scope: Python variables can be accessed outside loops, while C++ variables are limited to their loop scope.
• Rapid Prototyping: Python is preferred for rapid prototyping, while C++ is better for large-scale projects with complex requirements.
• Simplicity and Usability: Python is easier to learn and use due to its readability, making it ideal for machine learning. C++ is more complex and closer to low-level languages.
• Tasks: C++ is better for system programming and low-level tasks, while Python excels in scripting and application development.
• Desktop Applications: Python efficiently develops cross-platform desktop applications, but C++ provides better performance.
• Cross-Platform Compatibility: Python runs on multiple platforms without recompilation, while C++ requires platform-specific recompilation.
• Metaprogramming: C++ has better support for template metaprogramming.
• Real-Time Programming: C++ is more efficient for real-time applications and system programming.
• Audio and Video Processing: Python’s real-time audio and video processing capabilities are limited compared to C++.

C++ can be 10 to 100 times faster than Python, depending on computational complexity. Python programmers tend to use more RAM compared to C++ developers. If speed is a critical factor for your project, C++ might be the better choice.

Both languages have strengths and weaknesses. However, the fundamental difference between Python and C++ depends on their respective application areas. Choose a language based on where and how your code will be used. If you are working in data science, web development, or scripting, Python is preferable. For game development, embedded systems, and high-performance computing, C++ is a better option. If you are new to programming, Python is easier to learn.
