Exercise 2

Use slicing to write Python code to print a 6-character substring of 'Launch School' that begins with the first c.

Solution

my_str = 'Launch School'
print(my_str[4:10])                   # ch Sch

The first c occurs at index 4, so that's our start value for the slice. Since we want 6 characters, the stop value is at index 4 + 6 or 10. Note that the character at index 10 is not included in the result.

If you want to determine the location of the substring programmatically, you can do this:

my_str = 'Launch School'
start = my_str.find('c')
print(my_str[start:start + 6])        # ch Sch

Some error checking might be advisable there.

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
