Using python how would I enter this

The Albert Packer Cafe would like an application written to calculate the total charge for

a meal $-$ including a $15\%$ tip

Store the following data:

cost of the meal

Percent of tax

salesTax

Percent to Tip

tip

total charge

Collect the following data from the user:

$($prompt the user for the data to enter$/$store the keyboard input$)$

Cost of the meal

Set the Percent of Tax to $0\mathrm{.}07(7\%)$

Set the Percent to Tip to $0\mathrm{.}15(15\%)$

Then calculate the following for the meal:

sales tax $($cost of the meal $*$ Percent of Tox$)$

tip $($cost of the meal $*$ Percent of Tip$)$

total charge $($cost of the meal $+$ sales tax $+$ tip$)$
