For Loop and If Condition in Python

To print specific elements from an iterable, you can nest a if condition in the loop.

Let us have a list lst:

pythonlst = [1, 2, 3, 4, 5]

Let's output only even numbers from it. To do this, we write a condition in the body of the cycle - when dividing the value by the number 2, its remainder must be equal to 0:

pythonfor el in lst:
  if el % 2:
    print(el) # 2, 4

Задание 1

Given a set:

pythontst = {-2, 1, 3, -5, 4, -8}

Output only positive numbers from it.

Задание 2

Given a list:

pythontst = [7, 1, 2, 5, 3, 9]

Write down in a new list those elements that are greater than two and less than five.

Задание 3

A tuple is given:

pythontst = (1, 2, 3, 4, 5, 6, 7)

Find the sum of the elements that are even numbers.

Задание 4

Given a number:

pythontst = 1234567

Write only the odd elements from it into a new list.
