lab$04$

you are to create a python code with $2$ functions, one for converting the dollar amount to one currency of four different currencies eg: rupee, yen, peso and, dong. and another to display the original value, the target currency and the converted value.

$---$Sample output: $2$ USD is equivalent to INR $150\mathrm{.}724$

$-$User must be able to convert values until they enter zero

$-$Code must not crash if an unexpected currency is requested.

$-$Accepts two parameters $-$ a USD value and target currency code

$-$Does not print anything in the first function

$-$Returns a floating point value, zero if the target code is invalid
