Consider the Python object

z $=\{1$: 'one', $2$: 'two', $3$: 'three'$\}$

$($a$)$ What kind of object is z$?$ What is its length?

$($b$)$ Which components are keys? Which are values?

$($c$)$ How would I get the value associated with the key $2?$

$($d$)$ Use Jupyter$$s help facilities to figure out what z$.$keys$()$ does. Ditto z$.$values$().$ Try them to verify.

$($e$)$ What does list$($z$.$keys$())$ do$?$

$($f$)$ What does list$($z$.$values$())$ do$?$

$($g$)$ What does list$($z$)$ do$?$
