Code Explanation:
1. Importing reduce from functools
from functools import reduce
What it does: Imports the reduce function from Python’s functools module.
Why it’s needed: reduce allows you to apply a function cumulatively to the items of a list (or any iterable), reducing it to a single value.
2. Creating a list of numbers
nums = [2,3,4]
What it does: Defines a list nums containing numbers 2, 3, and 4.
Purpose: These numbers will be multiplied together.
3. Calculating the product of all numbers
total = reduce(lambda x,y: x*y, nums)
Breaking it down:
lambda x,y: x*y is an anonymous function that multiplies two numbers.
reduce(function, iterable) applies this function cumulatively:
First: 2 * 3 = 6
Then: 6 * 4 = 24
Result: total = 24
Why: reduce is perfect for operations like multiplication or addition across a list.
4. Getting the length of the list
length = len(nums)
What it does: Uses len() to count how many elements are in nums.
Result: length = 3
5. Printing the results
print(total, length)
What it does: Prints the product of the numbers (total) and the number of elements (length) in the list.
Output:
24 3
