There is an easier way to do it in Python using something called a while loop. We will learn exactly
eBook
how they work in a future chapter, but now would be a good time to show a preview. The while
statement repeats the suite, of three lines of code, while n is not zero. We will see the while statement
in future chapters, but it makes the program much smaller. The example below will work for virtually
any positive integer, just change the first line.

1| n = 101
Edition
2| while(n):
3| r = n % 2
4| n = n //2
5| print(n,r)

Another Example:

Convert 364 to binary. Free
364 / 2 = 182 r 0 0

182 / 2 = 91 r 0 00
91 / 2 = 45 r 1 100

1100
45 / 2 = 22 r 1 eBook
22 / 2 = 11 r 0 01100
11 / 2 = 5 r 1 101100

5 / 2 = 2 r 1 1101100
2 / 2 = 1 r 0 Edition
01101100
1 / 2 = 0 r 1 101101100
