Exercise 3

Write a program that uses a multiply function to multiply two numbers and returns the result. Ask the user to enter the two numbers, then output the numbers and result as a simple equation.

$ python multiply.py
Enter the first number: 3.1416
Enter the second number: 2.7183
3.1416 * 2.7183 = 8.53981128

Solution

def multiply(left, right):
    return left * right

def get_number(prompt):
    entry = input(prompt)
    return float(entry)

first_number = get_number('Enter the first number: ')
second_number = get_number('Enter the second number: ')
product = multiply(first_number, second_number)
print(f'{first_number} * {second_number} = {product}')

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
