Có thể chuyển đổi mã C++ thành python không?
It depends to what degree… - Yes and No…
First of all - both languages are very different. So translation would not be an easy task, also when your C++ code would (for example) do something Python by design can’t (like executing Assembler), its pretty much over (except if you provide a library - written in C++, which then would provide Python with those abilities) - but then its getting really hacky…
Now, how could it be done:
When you are able to abstract all instructions - and provide an equivalent to any, you can basically translate it - even with a different syntax… - Programming languages always follow their Syntax, which makes translation possible (without the use of AI).
Now this might become a rather long example, but just to demonstrate you, how difficult it would be, even with a rather easy snippet of code - i’ll mostly be using Java throughout that demo:
Original C++ snippet:
#include
int n = 3;
if (n > 0) {
std::cout << "n is positive" << "\n";
}
std::cout << "Bye World!" << "\n";
Now, first you’d want to split this into logic entities. We have 3 Entities - 1 Assignment, 1 If-clause and 1 function-call.
To split this, you’d probably use a RegularExpression as those are incredibly mighty when it comes to such use-cases - but that would really blow up this demo now, because you’d also have to differentiate between blocks that need or do not need curly braces… but lets assume, you have split that sourcecode into the following Strings:
String[] entities = {
"#include ",
"int number = 3;",
"if (number > 0) { std::cout << "n is positive" << "\n"; }",
"std::cout << "goodbye cruel world." << "\n";" }
Lets ignore the #include direction for now (I’ll come back to that later…)
Lets make an abstract class:
public abstract class Entity {
public String toPython();
public String toCpp();
}
Next, since "int number = 3;" is an Assignment, lets create a class AssignmentEntitty:
public class AssignmentEntity extends Entity {
String targetType;
String traget;
String source;
public String toPython() {
return target + " = " + source;
}
public String toCpp() {
return targetType + " " + target + " = " + source + ";";
}
}
You’ll notice that i skipped the Constructor - to save a few lines…
For that If Clause - you’d also want to extend from Entity like so:
public class IfEntity extends Entity {
ConditionEntity condition;
ArrayList onTrue;
ArrayList onFalse;
public String toPython() {
return "if " + condition.toPython() + ":\n\t" + onTrue.toString();";
}
public String toCpp() {
return "if (" + condition.toCpp() + ") {" + onTrue.toCpp() + "}";
}
}
This code will not work - i’ve taken a few shortcuts to make it easier for the reader. You cant run "toPython()" on an ArrayList like that of course - you’d have to make another Entity and so on and so on - also that ConditionEntity does not exist yet - and maybe is not even necessary…
To create all those entities, you now parse that first Array and create those entities in the order they appear. - If you do everything right, you will end up with working Python-Code, when you call your top most toPython()… but - this is pure overkill!
About the "#include" directive, well - to make things even more complicated, you’d have to also add to every of your entities, if they require special includes, and keep track of those aswell…
I do not think that there will ever be a program to really translate C++ to Python, but… for sure this would be a great practice…
Back in 2002, i once had to write software that would translate bytecode coming from an MQL2-Compiler back to MQL. And that above approach was, what i used. It worked fine, but it was a hell of a work…
I hope this was not too boring, and could at least point you in a direction - as well as maybe help others with a similar Problem. Anyways - this answer is by no means in any way complete… - i just hope it helps…+01: from libc.math cimport sqrt __pyx_t_1 = PyDict_New(); if (unlikely(!__pyx_t_1)) {__pyx_filename = __pyx_f[0]; __pyx_lineno = 1; __pyx_clineno = __LINE__; goto __pyx_L1_error;}
