The difference between scripting Shell and Python under Linux

Ideas and algorithms can be the same, but the syntax is different AH. For example 1+2+3+4+ ..., and over 10000
Shell,c,python to achieve similar ideas.
1, the shell implementation while loop
#!/bin/sh
Sum=0
I=0
While [$sum-LT 10000];
Todo
i=$ (($i + 1)); #or ((i++));
sum=$ (($sum + $i)); #or ((sum=sum+i));
Done
Echo $i, $sum
2, c implementation while loop
#include "stdio.h"
int main ()
{
int sum=0;
int i=0;
while (sum<10000)
{
i++;
Sum=sum+i;
}
printf ("%d,%d\n", i,sum);
return 0;
}
3, shell implementation for loop
#!/bin/sh
Sum=0
for ((I=1;; i++));
Todo
sum=$ (($sum + $i)) #or ((sum=sum+i))
If [$sum-gt 10000];then
Break
Fi
Done
Echo $i, $sum
4, c implementation for loop
#include "stdio.h"
int main ()
{
int sum=0;
int i;
for (I=1;; i++)
{
Sum=sum+i;
if (sum>10000) {
Break
}
}
printf ("%d\n", sum);
return 0;
}
5, Do/while implementation
#include "stdio.h"
int main ()
{
int sum=0;
int i=0;
Todo
{
i++;
Sum=sum+i;
}while (sum<10000);
printf ("%d,%d\n", i,sum);
return 0;
}
6, Python implementation while loop
#!/usr/bin/python
Sum=0
I=0
While sum < 10000:
i=i+1;
Sum=sum+i;
Print i,sum;
