  age = 12
  print(f"I am {age} years old")

2. 프로젝트 : 팁 계산기

print("Welcome to the tip calculator!")
bill = float(input("What was the total bill? $"))
tip = int(input("What percentage tip would you like to give? 10 12 15 "))
people = int(input("How many people to split the bill? "))

pay=round(bill*(1+tip*0.01)/people,2)

print(f"Each person should pay : {pay}")
