C++ vs. Python: All You Need to Know

C++, with its roots stretching back to the early ’80s, is revered for its power and precision, offering unparalleled control over computer resources. On the other hand, Python has all the grace of a modern language that champions readability and simplicity and is a favourite of beginners and seasoned developers. Whether you’re developing a high-performance game, a data analysis tool, or anything in between, having the “C++ vs. Python” discussion can determine the success rate of your next IT project.

Which is Better: C++ or Python?

C++ and Python are two of the most popular programming languages IT industry professionals use, but they have some key differences:

What is C++?

C++ is a mid-level language that gets you closer to the hardware. It’s a compiled, statically typed language, meaning your code is translated into machine-readable instructions before execution and variables have a fixed type.

Advantages of C++:

  • Fast and efficient – The compiled code runs natively.
  • Complex – It has a steep learning curve and lots of syntax to remember.
  • Used for system/application software development, drivers, and video games.

What is Python?

Python is a high-level, general-purpose language. It’s dynamically typed, meaning variables can be reassigned to different types, and interpreted, so the source code is executed line by line.

Advantages of Python:

  • Easy to read and write. The simple syntax is easy to pick up.
  • Used for both scripting and application development.
  • Slower than compiled languages. The interpreted nature makes it less efficient.
  • Used for web and software development, system administration, and scientific computing.

Both languages have their place. The right choice depends on your needs, priorities, and experience level.

Performance: Speed and Efficiency

When it comes to speed and performance, C++ has the upper hand. As a compiled language, C++ code is converted into low-level machine code that can be executed directly.

Python is an interpreted language. This requires an additional translation step, making Python generally slower than C++.

For CPU-intensive tasks like image processing, video editing, or gaming, C++ is the better choice. Its code runs closer to the hardware, providing greater control and optimization. Python is better suited for general-purpose programming where execution speed is not critical.

Code needs to be compiled and then linked before execution.Code can be run immediately.
Static typing: variables must be declared before use.Dynamic typing: you can assign values to variables on the fly.
Low-level memory manipulation. Suitable for system/hardware programming.Automatic memory management. Suitable for general purposes.

C++ can be up to 100 times faster than Python for certain tasks. However, Python’s simplicity and shorter development time also translate to lower costs. Python offers sufficient performance for most regular desktop applications or web development services.

Syntax: How C++ and Python code compare

The syntax of C++ and Python are quite different, reflecting their different design principles. C++ syntax is influenced by C, so it’s a bit more complex, while Python aims for simplicity and readability.


In C++, you declare variables before using them and specify their type and end statements with semicolons:

int x = 5;

In Python, you don’t need to declare variables before assigning them or specify types:

x = 5


Defining functions in C++ requires specifying the return value type and arguments:

int add(int x, int y) {
return x + y;

In Python, functions are defined using the def keyword, without specifying types:

def add(x, y):
return x + y


The main loops in C++ are for and while loops:

for (int i = 0; i < 5; i++) {
// ...

Python has similar loop constructs but with simpler syntax:

for i in range(5):
# ...


C++ classes require explicitly defining constructors, destructors, and access modifiers like public and private. For example:

class Person {
Person () { ... }  // Constructor
~Person () { ... }  // Constructor
void sayHello() { ... }

Python classes are simpler:

class Person:
def __init__(self):  # Constructor
ef say_hello(self):

In summary, C++ has a more complex syntax with more rules while Python aims for simplicity and readability.

Uses and applications

C++ is a statically typed, compiled language ideal for:

  • High-performance software such as operating systems, database development engines and graphics engines.
  • Embedded systems and IoT devices. Its code can run on microcontrollers and other compact embedded systems.
  • Desktop applications that require speed and efficiency.

C++ is a “lower-level” language that gives programmers solid control over memory usage and hardware resources. However, this also means it has a steep learning curve and is more prone to errors.

Python is a dynamically typed, interpreted language great for:

  • Web and mobile development: Python’s simplicity and available web frameworks make it a popular choice for web apps, APIs, and mobile app development.
  • Data analysis and visualization: Python has powerful data analysis libraries like NumPy, SciPy, and Pandas.
  • Prototyping and scripting: Python’s ease of use and readability make it perfect for quickly building prototypes and scripts.
  • Education and training: Python’s simplicity and large collection of libraries also make it an excellent language for learning to code.

Python is a “higher-level” language, so it’s more abstracted from the hardware details. This makes Python easier to read and write, but also generally slower than compiled languages like C++.

C++ shines when performance and efficiency are top priorities, while Python is ideal for productivity, ease of use, and rapid development. Many applications combine C++ and Python in their tech stack, leveraging the benefits of each language.

C++ vs Python for machine learning

If you’re interested in machine learning, pick up a programming language. The two most popular options are C++ and Python. Which one should you choose? Here are some factors to consider:

  1. C++ is a lower-level, compiled language that’s been around since the 1980s. It gives you strong control over hardware resources but requires manual memory management. C++ powers major libraries like TensorFlow, PyTorch, and Keras. However, it has a steep learning curve and the low-level nature means you’ll spend more time focusing on technical details.
  2. Python is a higher-level, interpreted language that’s easier to pick up. It has a simple, readable syntax and is a popular, general-purpose language for ML research and application development. Python has a milder learning curve, allowing you to focus on the ML concepts and algorithms instead of language intricacies. Popular ML libraries like scikit-learn, Pandas, and NumPy are written for Python.

If you’re just getting started in ML, Python is probably your best choice. Once you have a solid ML foundation, you can learn C++ to comprehend what’s happening “under the hood” and for high-performance computing needs. Many data scientists are bilingual, using Python for prototyping and C++ for deployment.

For training ML models, both C++ and Python work well and have mature tooling. C++ may have a performance edge for large datasets or complex models, but for most needs, Python performs sufficiently.

The language you choose ultimately comes down to your priorities and long-term goals. If ease of use and productivity matter most, go with Python. If high performance and control are key, consider starting with C++. The good news is that knowledge in one language transfers well to the other. So you really can’t go wrong either way.
