And we will guide you on how to use the sum() function of Python as we did below. Hope you understand.

## More examples

**Example 1**: The basic sum() function

a = (3, 4, 5) # Apply sum() function x = sum(a) # Return result print("Sum =",x)

Output:

**Sum = 12**

**Example 2**: Increase results

a = (3, 4, 5) # Apply sum() function x = sum(a) print(x) # Plus 10 y = sum(a, 10) print(y)

Output:

**12**

**22**
