Python Tip Calculator

I was reviewing some fundamental tutorials covering Python programming and used this code below to create a simple Tip Calculator.  (https://www.codecademy.com/learn)

Nothing Fancy!! This was just for learning, but was kind of fun.  You can easily elaborate on what is provided by adding some additional conditionals with elif and/or else.

**Code provided below for easy copy/paste.

import sys
import datetime

meal = float(input('Please Enter the Meal Cost:  '))
tax = float(input('Please Enter the Tax %:  '))
tip = float(input('Please Enter the Tip Percentage %:  '))

date = datetime.datetime.now()

if tax >= 0:
    tax = tax * .01
if tip >= 0:
    tip = tip * .01

meal = meal + meal * tax
total = meal + meal * tip

output = round(total,2)
print("\nTOTAL\n")
print(date.strftime("%I:%M:%S %m/%d/%Y"),'\n$',output,'\n')
