$5.$ Lambda with Built$-$in Functions $-$ Sorting: You have a list of tuples where each tuple contains the name of a product and its corresponding price. Use a lambda function as a key argument to the sorted$()$ function to sort these products by price in ascending order. Print the sorted list.

products $=[{(}^{\text{'}}appl{e}^{\text{'}},1\mathrm{.}0),{(}^{\text{'}}banan{a}^{\text{'}},0\mathrm{.}5),{(}^{\text{'}}cherr{y}^{\text{'}},1\mathrm{.}5),{(}^{\text{'}}dat{e}^{\text{'}},0\mathrm{.}75)]$
