Here is the code in a Python dictionary, where the keys are letters and the values are the corresponding Morse codes.

morsecode $=\{\text{'}$a$\text{'}$: $\text{'}.-\text{'},$

$\text{'}$b$\text{'}$: $\text{'}-...\text{'},$

$\text{'}$c$\text{'}$:$\text{'}-.-.\text{'},$

$\text{'}$d$\text{'}$:$\text{'}-..\text{'},$

$\text{'}$e$\text{'}$:$\text{'}.\text{'},$

$\text{'}$f$\text{'}$:$\text{'}..-.\text{'},$

$\text{'}$g$\text{'}$:$\text{'}--.\text{'},$

$\text{'}$h$\text{'}$:$\text{'}....\text{'},$

$\text{'}$i$\text{'}$:$\text{'}..\text{'},$

$\text{'}$j$\text{'}$:$\text{'}.---\text{'},$

$\text{'}$k$\text{'}$:$\text{'}-.-\text{'},$

$\text{'}$l$\text{'}$:$\text{'}.-..\text{'},$

$\text{'}$m$\text{'}$:$\text{'}--\text{'},$

$\text{'}$n$\text{'}$:$\text{'}-.\text{'},$

$\text{'}$o$\text{'}$:$\text{'}---\text{'},$

$\text{'}$p$\text{'}$:$\text{'}.--.\text{'},$

$\text{'}$q$\text{'}$:$\text{'}--.-\text{'},$

$\text{'}$r$\text{'}$:$\text{'}.-.\text{'},$

$\text{'}$s$\text{'}$:$\text{'}...\text{'},$

$\text{'}$t$\text{'}$:$\text{'}-\text{'},$

$\text{'}$u$\text{'}$:$\text{'}..-\text{'},$

$\text{'}$v$\text{'}$:$\text{'}...-\text{'},$

$\text{'}$w$\text{'}$:$\text{'}.--\text{'},$

$\text{'}$x$\text{'}$:$\text{'}-..-\text{'},$

$\text{'}$y$\text{'}$:$\text{'}-.--\text{'},$

$\text{'}$z$\text{'}$:$\text{'}--..\text{'}\}$

For example, the Morse code for 'a boy' is $\text{'}.--...----.--\text{'}$

We will adopt the convention that in the Morse code output there is always a space between two letters and there are three spaces between words. Write a function called morse$($mystring$,$ code$)$ that takes as input a string and a dictionary $($e$.$g$.,$ the Morse code dictionary above$),$ and returns the Morse code version of that string. You can cut$-$and$-$paste the dictionary above into your function. For example:

$>>>$ morse$(\text{'}$a boy', morsecode$)$

$\text{'}.--...----.--\text{'}$
