How to Convert C++ to Python

Share This Post

If you are a beginner in the programming world, chances are that you’re still confused about the working of these languages to convert C++ to Python.

Many rookies wonder whether it is possible to convert a code from one programming language to another such as C++ to Python.

There is no simple answer to this question so we will have to go into details. Without further ado, let us get straight into it.

You can easily convert your C++ code into Python with a few lines of simple text editing.

For example, you might want to do this if there are some specific functions that only work in one programming language.

Now then you can do by translating them both will become easier!

Can I Convert C++ to Python?

If we are speaking fundamentally, then yes you can most definitely convert your C++ program to Python.

This is because all programming languages are Turing complete which means that all languages can achieve the same algorithms, solve the same problems, make similar programs, and so on.

Therefore keeping all this in mind, it is completely possible to convert your C++ program to Python.

On the other hand, although it is possible to convert your program into Python, it is not easy as it sounds. What might help you is a transpiler which takes a program from one language to another.

That being said, it must be noted that C++ and Python have significant paradigm differences that went into the language design which affects the ability to convert code from one language to another.

Convert C++ to Python

To add to this, Python is a high-level language compared to C++ and can interact with the memory easily unlike C++. Still, the transpilers do their best to bridge this gap, which usually fails or makes incorrect assumptions.

To have a better understanding, let us take a look at an example of C++.

#include stdio; 
 
int main(){ 
char* a = "Hello world"; 
printf("%s", a); 
return 0 
} 
PYTHON:
def main(): 
a = "Hello world" 
print(a) 
return 0 

Explanation

Sample codes for C++ and Python check above respectfully.

On running these codes through a transpiler, the results are different. This is because of several reasons, one of which is that the C language automatically runs the main function whereas Python has a function defined that is never called. Official lib: here

To tackle this issue, one can use a smarter transpiler that either call the function or makes use of the __init__ method. It would not remain literal transpiring anymore.

Furthermore, one can run into other issues namely type calling, memory access issues, and so on. Several other issues may arise such as:

  1. You are going to have trouble using memcpy() memset(), as these constructs do not exist in Python.
  2. If your C++ program makes use of pointers, it will cause serious issues during transpiring since Python does not have pointers
  3. “Int” data types are also different for Python and C++ languages. In Python, int can grow to a large size and can only be limited by the memory, whereas in C the atomic integer types will all overflow, and there is a distinction between signed and unsigned.

C++ to Python conversion is a process of transforming C++ code into equivalent Python code. This can be done either by manually translating the code or by using an automated tool. In general, the Python code will be more concise than the corresponding C++ code, but it may not be as efficient.

Conclusion

Yes, you can convert a C++ code into Python but it is not as easy as it sounds.
