Answer:
Here is an example of a code that performs the operation of adding the numbers from 12 to 2500 using a function in Python:
def add_numbers(start, end):
result = 0
for i in range(start, end+1):
result += i
return result
print(add_numbers(12, 2500))
Step-by-step explanation:
The function "add_numbers" takes two arguments, "start" and "end", which represent the range of numbers to be added. Inside the function, a variable "result" is initialized to zero, and a for loop is used to iterate through the range of numbers from "start" to "end". At each iteration, the current number "i" is added to the "result" variable. Finally, the function returns the "result" variable, which contains the sum of the numbers in the given range.
In the last line of the code, the function is called with the arguments 12 and 2500, and the result will be the sum of the numbers from 12 to 2500.
It's important to note that, while this code uses a for loop to add the numbers, there are other ways to calculate the sum of a sequence of numbers like using the sum() function, or the Gauss formula.
