[Tutor] Cramer's Rule

[Keshav Inderjeet]

Hello everyone I have been tryin to convert the 
following C- codes in python but always receiving error messages. Please Help. 
The program is about Cramer's rule 
 
 
#include<stdio.h>
 
#double finddet(double a1,double a2, double 
a3,double b1, double b2,double b3, double c1, double c2, double c3); 

 
void main():
{
     double a1, a2, a3, b1, 
b2, b3, c1, c2, c3, d1, d2, d3,det, detx, dety, detz;
     
     
printf("\n a1?"); /*Input Coefficients*/
     scanf("%lf",&a1);
     
printf("\n b1?");
     scanf("%lf",&b1);
     printf("\n 
c1?");
     scanf("%lf",&c1);
     printf("\n d1?");
     
scanf("%lf",&d1);
     printf("\n a2?");
     
scanf("%lf",&a2);
     printf("\n b2?");
     
scanf("%lf",&b2);
     printf("\n c2?");
     
scanf("%lf",&c2);
     printf("\n d2?");
     
scanf("%lf",&d2);
     printf("\n a3?");
     
scanf("%lf",&a3);
     printf("\n b3?");
     
scanf("%lf",&b3);
     printf("\n c3?");
     
scanf("%lf",&c3);
     printf("\n d3?");
     
scanf("%lf",&d3);
 
     det=finddet(a1,a2,a3,b1,b2,b3,c1,c2,c3);   
/*Find determinants*/
     detx=finddet(d1,d2,d3,b1,b2,b3,c1,c2,c3);
     
dety=finddet(a1,a2,a3,d1,d2,d3,c1,c2,c3);
     
detz=finddet(a1,a2,a3,b1,b2,b3,d1,d2,d3);
     
     if(d1==0 && 
d2==0 && d3==0 && det==0)
          printf("\n Infinite 
Solutions\n ");
     else if(d1==0 && d2==0 && d3==0 
&& det!=0)   /*Print Answers depending on various 
conditions*/
          printf("\n x=0\n y=0, \n z=0\n ");
     else 
if(det!=0)
          printf("\n x=%lf\n y=%lf\n z=%lf\n", (detx/det), 
(dety/det), (detz/det));
     else if(det==0 && detx==0 && 
dety==0 && detz==0)
          printf("\n Infinite Solutions\n 
");
     else
          printf("No Solution\n ");
 
}
 
double finddet(double a1,double a2, double 
a3,double b1, double b2,double b3, double c1, double c2, double c3)
{
     
return ((a1*b2*c3)-(a1*b3*c2)-(a2*b1*c3)+(a3*b1*c2)+(a2*b3*c1)-(a3*b2*c1)); 
/*expansion of a 3x3 determinant*/
}
