Help convert decimal to binary.
Consider what binary numbers represent. The right-most bit represents the ones place. The adjacent bit represents the two's place, then four, then eight, and so on.
14 decimal is 1110 binary
Now, it turns out that when dividing a number by 2 and rounding down, it's representation in binary is equivalent to throwing the right-most bit away.
7 decimal is 111 binary 3 decimal is 11 binary 1 decimal is 1 binary
Now, you might recall that a binary number is even if it's right-most bit is 0 and odd otherwise. So let's walk through one more time.
14 decimal is 1110 binary
The last bit is 0 and 14 is even.
7 decimal is 111 binary
The last bit is 1 and 7 is odd.
3 decimal is 11 binary
The last bit is 1 and 3 is odd.
1 decimal is 1 binary.
The last bit is 1 and 1 is odd.
This is why the program checks if the number is even or odd at every step. Now, we analyzed the original input (14) from the right-most bit to left. If we printed the result in this order, we would get:
14 decimal is 0111
Notice this result is backwards. Remember that at each step, we analyzed the right-most bit by checking if the result was even or odd. Luckily, the program doesn't print at each step until after the next step is finished (recursion). This allows the result to be printed in the correct order.
Now, we talked about the recursive form, which hopefully is more clear now. Notice though, that we only recurse if the number is greater than 1. If our input is 0 or 1, there is no recursive call. Nicely though, 0 is 0 in binary and even. 1 is 1 in binary and odd. So, everything checks out.
Hope that helps.

Real life subnetting: With some experience you just know the numbers for the most often used subnet sizes. Use a calculator to avoid mistakes. For the exam: Memorize the subnet und wildcard table. Write it down at the beginning of the exam. That being said, it is important to understand the binary math behind the subnetting. There are lots of good videos explaining different methods. Check out what works best for you.

You can use int and set the base to 2 (for binary):
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> int(binary, 2)
25
>>>
However, if you cannot use int like that, then you could always do this:
binary = raw_input('enter a number: ')
decimal = 0
for digit in binary:
decimal = decimal*2 + int(digit)
print decimal
Below is a demonstration:
>>> binary = raw_input('enter a number: ')
enter a number: 11001
>>> decimal = 0
>>> for digit in binary:
... decimal = decimal*2 + int(digit)
...
>>> print decimal
25
>>>

In binary, 8 is represented as 1000. Reading from right to left, the first 0 represents 20, the second 21, the third 22, and the fourth 23; just like the decimal system, except with a base of 2 rather than 10. Since 23 = 8, a 1 is entered in its position yielding 1000. Using 18, or 10010 as an example: 18 = 16 + 2 = 24 + 21 10010 = (1 × 24) + (0 × 23) + (0 × 22) + (1 × 21) + (0 × 20) = 18 · The step by step process to convert ...
