C++ and Python, two of the most popular and commonly used programming languages, aren’t only versatile and object-oriented, but they can be used to create a wide array of various programs and functional code.

For this reason, the discussion of Python vs. C++ is an intriguing subject, since both programming languages feature greatly different syntaxes, use cases, and overall approaches to programming. Hence, people find it difficult when choosing between the two programming languages for their software development needs.

Developed from the C language, C++ is considered the better option for large system development, but it is also the harder language of the two to master and write in, which is something that limits its usage.

On the other hand, Python is a high-level programming language. When writing code in Python, a variable can be used directly without being declared, whereas in C++, the program needs to be compiled to every operating system that has to run C++ code. But let’s not get ahead of ourselves.

In this article, we’ll discuss the advantages and disadvantages of using C++ vs. Python, along with the highlights, key differences between the two languages, and situations or projects that each language is best for.

C++ vs. Python: General overview

Frequently, you will find articles online that wax eloquent on the qualities of one programming language over another. Quite often, their goal is to promote one language while degrading the other. But the comparison we offer below looks at both Python and C++ as tools with different uses for different problems.

What is the Python programming language?

Python is one of the fastest-growing programming languages. The underlying goal of creating Python was its simplicity. It is one of the simplest languages to learn, given its close similarity to common English. Fundamentally, it is a high-level, interpreted, general-purpose, and object-oriented scripting language.

What are the key features of Python?

1. Interpreted

Like Perl and PHP, Python doesn’t demand program compilation before execution. So, you don’t have to run a compiler that turns source files into compiled class files. Instead, you run a .py file. What’s more, Python byte code compilation is automatic and entirely implicit.

2. High-level

Python is high-level, meaning it is created for programmers who prefer having the written code translated into a low-level language. Python should also be processed before running, which enables its portability—it can run on different kinds of computers with few or no modifications.

What are the differences between Python and C++?

Now, let’s compare the two languages based on various industry metrics, syntax, and general rules of programming.

  • When comparing Python vs. C++, speed is often the first aspect that people think about. C++ has a slight advantage over Python when it comes to speed, as it is pre-compiled, unlike Python, which runs code through an interpreter line by line.
  • In C++, you should allocate memory to new variables and free them after finishing a job. Not doing so can result in a memory leak. As C++ doesn’t offer garbage collection and uses pointers, memory leaks will become evident at some point. However, Python offers automatic memory management, so you don’t have to handle the memory you use directly.
  • Unlike C++, which is statically typed, Python features dynamic typing, meaning you don’t have to indicate the types of objects, which makes it more versatile. Additionally, Python offers a lot of flexibility—its variables can be used in any context.
  • In C++, semicolons are used to register the end of the statement, while Python treats the end of the line as the end of the statement without a semicolon. Nevertheless, you can use the backslash sign to have the statement continue for multiple lines.
  • “Python dictionary” and “C++ map” are two terms that refer to the terminology of the languages. A map in C++ is a container that stores values indexed by a key. While a dictionary in Python has a similar role, it is more flexible because the keys and values don’t have to be the same type.
  • C++ comes with many syntaxes but doesn’t have indentation rules that make the code appear complicated. Python is similar to everyday English, so it is easier to read and write. Hence, its indentation helps a programmer stay aware of every open bracket.
  • Boolean expressions are vastly different in Python and C++. C++ marks are true or false based on numeric values. Everything marked 0 is false, and other numeric values are true. In Python, none and false constants are false as empty sequences or collections.
  • Error handling is easier in C++ than in Python, as you have to declare the type of data when you begin using it with C++. Nonetheless, the code you write in Python is shorter and easier to maintain because you don’t have to declare its type at the beginning.

Pros and cons of the Python programming language

Advantages of Python
  • Python was developed to improve coding productivity. So, it is ideal if you want to work quickly and effectively.

  • Python codes should often be tested before execution, since runtime errors are common and the data types of variables keep changing all time.

Pros and cons of the C++ programming language

Advantages of C++
  • C++ is a portable language, meaning it can be used on different interfaces or operating systems to run the same program.
  • It is a multi-paradigm programming language that features a framework a programmer can leverage to code various styles.
  • Being an object-oriented language, C++ makes it easier to sort data, and the code can be reused.
  • C++ allows for low-level manipulation due to its close relation to machine languages. This is beneficial for projects where you need the software to work well with the hardware.
  • The programmer manages memory while using C++, offering you more control.
  • C++ is entirely compatible with the C programming language, meaning any error-free C program can work as a C++ program.
  • It is a language with great scalability. So, it can run on small and large scales based on the program it has been written.
  • There is a large community of C++ users, meaning users get a lot of support, free tutorials, and guides.
Disadvantages of C++
  • Pointers in C++ take up a lot of memory and are pretty tricky to master.
  • Using an object-oriented programming language like C++ comes with many security issues.
  • While you have the ability to control memory management with C++, it lacks a garbage collector feature that automatically filters out unnecessary data.
  • C++ doesn’t support built-in code threads.
  • The object orientation system in C++ is considered quite essential compared to other programming languages.
  • During instances when the data points to the same place from two different starting points, the program can get the coding mixed up.
  • It is often difficult for beginners to learn how to code in C++, since the syntax is complex and the standard library is small.

Final thoughts on Python vs. C++

When it comes to choosing between Python and C++, it usually depends on the kind of software or program you want to develop.

For example, C++ is often used in embedded systems, game development, 3D or visual design programs, as well as for building operating systems or web browsers and portals. On the other hand, Python is a scripting language that is ideal for machine learning contexts, data analysis, and backend web development.

At the end of the day, comparing Python and C++ leads us to one conclusion: Python is easier to use and features a great support system for AI and ML frameworks when it comes to simplicity. However, C++ is much faster performance-wise. After all, Python is an interpreted language, which makes it difficult for it to stand up to a compiled language such as C++.
