In Coding example $2\mathrm{.}3$ How much are these mangos, you were asked to determine the total cost and set the output to two decimal places.

How can you ensure that the output always has two decimal points?

$\text{'}[\mathrm{.}2$f$]\text{'}.$format$()$

$\{$:$2f\}$ format$()$

$\text{'}\{.\mathrm{.}2$f$\}\text{'}.$format$()$

format' $\{$:$2f\}\text{'}$
