Country Statistics Lookup$-$Multiple Measures

Assume a program begins with the statement:

allData

$\text{'}$US$\text{'}$: $\{\text{'}$pop$\text{'}$:$325\mathrm{.}7,\text{'}$gdp$\text{'}$: $19\mathrm{.}39,\text{'}$ccy$\text{'}$: 'USD', $\text{'}$fx$\text{'}$: $1\mathrm{.}0\},$

$\text{'}$CA$\text{'}$: $\{\text{'}$pop$\text{'}$: $36\mathrm{.}5,\text{'}$gdp$\text{'}$: $1\mathrm{.}65,\text{'}$ccy$\text{'}$: 'CAD', $\text{'}$fx$\text{'}$: $1\mathrm{.}35\},$

$\text{'}$MX$\text{'}$: $\{\text{'}$pop$\text{'}$:$129\mathrm{.}2,\text{'}$gdp$\text{'}$: $1\mathrm{.}15,\text{'}$ccy$\text{'}$: $\text{'}$MXN$\text{'},\text{'}$fx$\text{'}$: $19\mathrm{.}68\}$

$\}$

Write subsequent statements that $($in a loop$)$ prompt the user for a country code $($US$,$ CA$,$ or MX$),$ then prompt for a

measure name $($pop$,$ gdp$,$ ccy$,$ or fx$),$ then look up in the above dictionary for the corresponding value, and display that value.

Example run:

Please enter a country code: CA

Please enter a statistic: pop

CA pop $=36\mathrm{.}5$

Your program should handle the cases where a user$-$entered country code or measure name is not found.
