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

product = 1 for _ in range(N): product *= int(input()) print(product) |
- Reading the Number of Integers:
- The
input() function reads the first line of input.
- The
int() function converts this input to a positive integer and stores it in the variable N.
- Initialize the Product:
- A variable
product is initialized to 1. This will be used to store the product of the N integers.
- Reading and Multiplying Integers:
for _ in range(N):
product *= 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 multiplies it to product.
- Printing the Total Product:
- Finally, the
print() function outputs the value of product.
