Running a C Program from Python
import subprocess
cmd = "nameOfCProgram.c"
# Example
# cmd = HelloWorld.c
print ("Hey this is Python Script Running\n")
subprocess.call(["gcc",cmd]) #For Compiling
subprocess.call("./a.out")
#end thats all
The C Code
// DO KEEP BOTH PROGRAMS IN SAME LOCATION
// HelloWorld.c
#include<stdio.h>
int main()
{
printf("Hello World\n");
printf("This C program Running\n");
return 0;
