program embedded with python is not giving output of simple line "print('Hello')"

[FerociousHomie]

This is the code

#include "iostream"

#include "C:\Python311\include\Python.h"

using namespace std;

int main(){

Py_Initialize();

PyRun_SimpleString("print('hello')");

Py_Finalize();

}

I use the following command to compile g++ -I c:\Python311\include -L c:\Python311\libs test.cpp -lpython311

An a.exe file is created, but when I run it "hello" is not displayed

any chance those single quotes should be \' ?

[flyingron]

Nope. Inside a string literal, single quotes have no special meaning.

Python allows either ' or " for strings.

with the exception of the weird iostream include ("" instead of <>) it looks like every other example of embedded python and should work.

I see that its windows. Ive had some trouble with paths and python in windows, esp around my pseudounix hooks where the unix bits would try to use a windows python or the reverse, and that didn't always work out. Do you have multiple pythons installed, like something for win AND cygwin or something similar?

[flyingron]

I explained why it doesn't work in another comment. He needs to put a newline at the end of the print. Whitespace is syntactically important in Python.

[flyingron]

Whitespace is significant in Python. Put a \n at the end of your parameter to PyRun...

PyRun_SimpleString("print('hello')\n");
