笔记4：变量和命名

用到知识：变量

#变量（variabl）和命名

print("变量和命名")

#cars 数量为100
cars = 100

#汽车空间为4.0
space_in_a_car = 4.0

#驾驶员为100人
drivers = 30

#乘客为90人
passengers = 90

#剩余汽车 = 汽车数量 - 驾驶员
car_not_driven = cars -drivers

#能驾驶的车 = 驾驶员
cars_drivern = drivers

#车总容量 = 能驾驶的车 * 当个车空间
carpool_capacity = cars_drivern * space_in_a_car

#乘客平均坐车容量 = 总乘客/能驾驶的车
average_passengers_per_car = passengers / cars_drivern

print("There are",cars,"cars_available.")#这里有100辆车可用

print("There are only",drivers,"drivers available.")#但是仅有30个驾驶员

print("There will be",car_not_driven,"empty cars today.")#今天这将会有70辆空车

print("We can transport",carpool_capacity,"people today.")#我们能运送120人

print("We have",passengers,"to carpool today.")#今天有90人需要坐车
