Exercise 2

This question may be a little challenging if your math skills are rusty. Don't be afraid to take advantage of the hints. Try your best to solve the problem, but don't feel compelled to complete it if you become frustrated.

Use the REPL and the arithmetic operators to extract the individual digits of 4936:

One place is 6.
Tens place is 3.
Hundreds place is 9.
Thousands place is 4.

Each digit may require multiple Python statements.

It's easier to extract the digits right-to-left rather than left-to-right.

number % 10 returns the rightmost digit of a number. You can use this repeatedly to extract all of the digits.

Once you have the rightmost digit, how do you remove that digit from the number? If we start with 4936 and extract the 6, how do we now reduce our number to 493?

You can remove the rightmost digit by using integer division.

Solution

>>> number = 4936
>>> ones = number % 10
>>> ones
6

>>> number = number // 10
493

>>> tens = number % 10
>>> tens
3

>>> number = number // 10
49

>>> hundreds = number % 10
>>> hundreds
9

>>> thousands = number // 10
>>> thousands
4

Note that you don't need to use % for the thousands digit.

Code Blocks

You can write code blocks using three backticks (```) followed by the language you want to show. For instance, if you wanted to write a Ruby code block you would write:

```ruby
class Foo
end
```

class Foo
end

You can also leave out the language identifier, doing this will make it so your code isn't highlighted at all, and all text will be white with no coloring.

```
class Bar
end
```

class Bar
end

Highlighting

You may highlight lines within your code blocks. This is a different type of highlighting, and isn't related to how the code within your code block may be colored depending on the language identifier used.
To highlight one or more lines of code, add # highlight on a separate line just before the first line you wish to highlight. To end highlighting, add # endhighlight on a separate line immediately after the last line you wish to highlight.

```ruby
def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
```

def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
