Exercise 5

Write a program named greeter.py that greets 'Victor' three times. Your program should use a variable and not hard code the string value 'Victor' in each greeting. Here's an example run of the program:

$ python greeter.py
Good Morning, Victor.
Good Afternoon, Victor.
Good Evening, Victor.

Solution

# This solution uses concatenation
name = 'Victor'
print('Good Morning, ' + name + '.')
print('Good Afternoon, ' + name + '.')
print('Good Evening, ' + name + '.')

# This solution uses f-string interpolation
name = 'Victor'
print(f'Good Morning, {name}.')
print(f'Good Afternoon, {name}.')
print(f'Good Evening, {name}.')

First, we create a variable that holds the value 'Victor'. With a variable, we don't need to hard code 'Victor' each time we greet him. Instead, we can use the variable as part of an expression. In our first solution, we use string concatenation; in the second, we use f-string interpolation.

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
