Python program to print positive numbers in a list

Last Updated : 29 Nov, 2024

In this article, we will explore various methods to o print positive numbers in a list. The simplest way to do is by using for loop function.

Using Loop

The most basic method for printing positive numbers is to use a for loop to iterate through the list and check each element.

Python

a = [-10, 15, 0, 20, -5, 30, -2]  # Using a for loop to print positive number for val in a:     if val > 0:         print(val)

Output

15 20 30

Explanation:

Iterates over the list numbers.
For each number checks if the number is greater than 0 (val > 0).
If the condition is true than print the number.

Using List Comprehension

List comprehension provides a compact and Pythonic way to filter positive numbers.

Python

a = [-10, 15, 0, 20, -5, 30, -2]  # List comprehension to filter positive numbers res = [i for i in a if i > 0] print(res)

Output

[15, 20, 30]

Using filter() Function

The filter() function can be used to filter out positive numbers from the list.

Python

a = [-10, 15, 0, 20, -5, 30, -2]  # Using filter() to get positive numbers res = filter(lambda x: x > 0, a)  # Convert filter object to list and print print(list(res))

Output

[15, 20, 30]

Perfect Number Program in Python

A Perfect Number is a positive integer that is equal to the sum of its proper divisors, excluding the number itself. Example: 6 is a perfect number because its divisors (excluding itself) are 1, 2, and 3, and their sum is 6 (1 + 2 + 3 = 6).28 is a perfect number because its divisors are 1, 2, 4, 7,
