About the A+b+c problem three languages solution, Java, C language, Python

The original question is this way:

This is a very simple topic, designed to examine your basic ability to program. Don't think it's hard. Enter a row that includes three integers, a, B, and C separated by a space (the data range is between -40~40). The output is one row, the result of the "a+b+c" calculation.
Sample 1

Input:

22 1 3

Output:

26

Since I have just come in contact with Python, so the code is a bit long, I hope there is great God can point out, help me improve, I am grateful. Let's start with my code, in the order of Java, C, Python

Java:

Import Java.util.Scanner;
Class Main
{public
   static void Main (string[] args)  
   {   
          int a,b,c;
         Scanner input=new Scanner (system.in);
        A=input.nextint ();
        B=input.nextint ();
        C=input.nextint ();
         if ((a>=-40&&a<=40) && (b>=-40&&b<=40) && (c>=-40&&c<=40) )
        System.out.println (a+b+c);
        else
        System.out.println ("Erro");
    }

C Language:

#include <stdio.h>
int main (void) {
    int A, b, C;
    scanf ("%d%d%d", &a, &b, &c);
    if (A > | | A < -40 | | b > | | | b < -40 | | c > | | | c < -40) return
        0;
    printf ("%d", a+b+c);
    
    return 0;
}

Python:

LST = Raw_input (). Split (")
sum = 0 for
i in LST:
    sum = sum+int (i)
print sum

As for other languages, such as what C++/ruby, not yet. Just a little bit of the three languages posted. Also hope to master a lot of advice.
