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.
C++ and Python are two of the most popular programming languages IT industry professionals use, but they have some key differences:
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.
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.
Both languages have their place. The right choice depends on your needs, priorities, and experience level.
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.
| C++ | Python |
|---|---|
| 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.
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:
```cpp
int x = 5;
```In Python, you don’t need to declare variables before assigning them or specify types:
```python
x = 5
```Defining functions in C++ requires specifying the return value type and arguments:
```cpp
int add(int x, int y) {
return x + y;
}
```In Python, functions are defined using the def keyword, without specifying types:
```python
def add(x, y):
return x + y
```The main loops in C++ are for and while loops:
```cpp
for (int i = 0; i < 5; i++) {
// ...
}
```Python has similar loop constructs but with simpler syntax:
```python
for i in range(5):
# ...
```C++ classes require explicitly defining constructors, destructors, and access modifiers like public and private. For example:
```cpp
class Person {
public:
Person () { ... } // Constructor
~Person () { ... } // Constructor
void sayHello() { ... }
};
```Python classes are simpler:
```python
class Person:
def __init__(self): # Constructor
...
ef say_hello(self):
d
...
```In summary, C++ has a more complex syntax with more rules while Python aims for simplicity and readability.
C++ is a statically typed, compiled language ideal for:
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:
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.
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:
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.
C++ and Python are two of the most popular languages for game development. Both languages have pros and cons for game development. Let’s see how they compare.
C++ is a fast, static programming language that gives you hard control over memory management. This makes it ideal for performance-critical tasks like:
C++ is also compatible with most game engines like Unreal and Unity. However, C++ can be more difficult to learn and work with due to its static typing and complex syntax.
Python is a very beginner-friendly, dynamically typed language. It’s easy to learn and code in Python so you can build games faster. Some other benefits of Python for game dev include:
However, Python is an interpreted language so performance may be an issue for complex 3D games. Python is also not as widely used with major game engines.
Both C++ and Python have strong communities and resources to support programmers.
Given its 40-year history, C++ has a very established community. The official organization is the ISO C++ Standards Committee which acts as the ultimate guide to the C++ programming language.
There are many online resources for C++ programmers:
There are also many books on C++ for beginners and experts alike. Some recommended titles are “The C++ Programming Language” by Bjarne Stroustrup, the creator of C++, and “Effective Modern C++” by Scott Meyers.
The Python community is also comprehensive and active. The official Python Software Foundation supports and promotes Python.
Some useful resources for Python developers include:
Both C++ and Python have a wealth of community support and learning resources online and offline. No matter which language you choose, you’ll have access to documentation, tutorials, Q&A forums, and books to help strengthen your skills.
Here are some of the most frequently asked questions about these two popular programming languages to help clear things up:
Yes, it is generally faster than Python. C++ is a compiled language, so its’ code is translated into machine-readable code before execution. Python is an interpreted language, meaning its code is executed line by line. Compiled code usually runs much faster.
Python is typically easier to learn than C++ for beginners. Python has a simple, clean syntax that is easy to read and write. C++ has a steeper learning curve due to its more complex syntax and lower-level access to memory.
It depends on your needs and goals. If you want to do web development, data science, or scripting, start with Python. If you want to get into software engineering, desktop applications, or gaming development, start with C++. Ultimately, both are useful languages to know, so you can’t go wrong either way.
Not exactly. While C++ is a powerful language suitable for various tasks, Python is better suited for some things. Python is ideal for scripting, web development, data analysis, and AI. C++ is better for system/software development, desktop applications, and performance-critical tasks.
On average, C++ programmers tend to earn higher salaries than Python programmers. According to Glassdoor, the average pay for a C++ developer in the US is around $114,000 annually. For Python developers, the average pay is around $107,000 per year. However, salaries vary significantly based on experience level, location, and specific job responsibilities.
The C++ vs Python decision. On one side, you have C++, the seasoned warrior of system-level tasks, with unmatched speed and precision. Python offers simplicity, flexibility, and a welcoming community for newcomers and pros tackling anything from web app development to data analytics.
