Executing a C program in python?

cinpy comes close using the awesome combination of tcc and ctypes

The following code is ripped from cinpy_test.py included in the package.

import ctypes
import cinpy

# Fibonacci in Python
def fibpy(x):
    if x<=1: return 1
    return fibpy(x-1)+fibpy(x-2)

# Fibonacci in C
fibc=cinpy.defc("fib",
                ctypes.CFUNCTYPE(ctypes.c_long,ctypes.c_int),
                """
                long fib(int x) {
                    if (x<=1) return 1;
                    return fib(x-1)+fib(x-2);
                }
                """)

# ...and then just use them...
# (there _is_ a difference in the performance)
print fibpy(30)
print fibc(30)

C is not a scripting language. You have to compile spa.c into an executable. You don't say your OS, but if Mac or Linux, try

  gcc spa.c -o spa

If that works, you now have a executable named spa. You can use python's os.system() to call it.

there is no such thing as a C script you need to compile C programs... if you compile to an executable, you can execute it using os.system(CommandLine)

Question is old still I felt one important part is missing!

C code can be compiled AND executed within Python script:

#include <iostream>
using namespace std;
int main(){
cout<<"Hello World\n";
return 1;
}



import subprocess
subprocess.call(["g++", "hello_world.cpp"]) # OR gcc for c program
tmp=subprocess.call("./a.out")
print("printing result")
print(tmp)


$ python main.py 
Hello World
printing result
