Sum of N numbers. Given an integer N followed by N integers, read these integers and print their sum. The first line of input contains the integer N, which indicates how many integers will follow. Each of the next N lines contains one integer. Calculate and print the sum of these N integers.

N = int(input()) total_sum = 0 for _ in range(N): total_sum += int(input()) print(total_sum) |
- Reading the Number of Integers:
- The
input() function reads the first line of input.
- The
int() function converts this input to an integer and stores it in the variable N.
- Initialize the Sum:
- A variable
total_sum is initialized to 0. This will be used to store the sum of the N integers.
- Reading and Adding Integers:
for _ in range(N):
total_sum += int(input())
- A
for loop runs N times, as indicated by range(N).
- Each iteration reads a number from the user using
input(), converts it to an integer with int(), and adds it to total_sum.
- Printing the Total Sum:
- Finally, the
print() function outputs the value of total_sum.
