Print all even numbers from 2 to 100

def​ ​print_numbers_version_one​():
​     number = 2
​   
​     ​while​ number <= 100:
​       ​# If number is even, print it:​
​       ​if​ number % 2 == 0:
​         ​print​(number)
​   
​       number += 1

​     number = 2
​   
​     ​while​ number <= 100:
​       ​print​(number)
​   
​       ​# Increase number by 2, which, by definition,​
​       ​# is the next even number:​
​       number += 2

Version 1 ends up looping 100 times, while Version 2 only loops 50 times. The first version then, takes twice as many steps as the second version.
