## How to be a happier person 😇

子曰：「其為人也孝弟，而好犯上者，鮮矣；不好犯上，而好作亂者，未之有也。君子務本，本立而道生。孝弟也者，其為仁之本與！」

> Yu Tzu* said:
'It is rare for a man whose character is such that he is good as a
son and obedient as a young man to have the inclination to transgress against his superiors; it is unheard of for one who has no such inclination to be inclined to start a rebellion. The gentleman devotes his efforts to the roots, for once the roots are established, the Way will grow therefrom. Being good as a son and obedient as a young man is, perhaps, the root of a man's character.'

## Python: For loop with range 🤖


- [x] Lost card (homework review)

## Homework

### Print primes in range

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Given two integers A and B, print all prime numbers between them, inclusively.

- Input
> 5, 20
- Output
> 5, 7, 11, 13, 17, 19

startNum = 45
endNum   = 100
prime = 1

# Ex. num = 7
for num in range(startNum, endNum+1):
    prime = 1
    # divisor = 2, 3, 4, 5, 6
    for divisor in range(2, num):
        if num%divisor == 0:
            prime = 0   
    # print the prime
    if prime:
        print(num)

### First N even, descending

Given an integer N, print all the even numbers from 0 to N in descending order.

- Input
> 9,
- Output
> 8 6 4 2 0

a = int(input())
for loop in range(a-1, -1, -2):
    print(loop)
