# 7.11 LAB: Car value (classes)
# Complete the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information.
# 
# Ex: If the input is:
# 
# 2011
# 18000
# 2018
# where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs:
# 
# Car's information:
#   Model year: 2011
#   Purchase price: $18000
#   Current value: $5770
# Note: print_info() should use two spaces for indentation.
