How do I reduce lists in Python with examples?

In Python, you can reduce lists using various approaches. The most common method is by using the `reduce()` function from the `functools` module. This function applies a rolling computation to sequential pairs of values in a list.

Here are a few examples of how to reduce lists in Python:

from functools import reduce # Example 1: Sum of all elements in a list numbers = [1, 2, 3, 4, 5] total = reduce(lambda x, y: x + y, numbers) print("Sum:", total) # Output: Sum: 15 # Example 2: Finding the product of all elements in a list numbers = [1, 2, 3, 4, 5] product = reduce(lambda x, y: x * y, numbers) print("Product:", product) # Output: Product: 120 # Example 3: Finding the maximum element in a list numbers = [1, 3, 2, 5, 4] maximum = reduce(lambda x, y: x if x > y else y, numbers) print("Maximum:", maximum) # Output: Maximum: 5
