本文通过一个具体的Python编程实例介绍了如何计算拼车系统的最大承载能力。该实例使用了基本的算术运算来计算可用车辆数、驾驶员数量、乘客数量及每辆车的平均乘客数等关键指标。

cars = 100
space_in_a_car = 4.0
drivers = 30
passengers = 90
cars_not_driven = cars - drivers
cars_driven = drivers
carpool_capacity = cars_driven * space_in_a_car
average_passengers_per_car = passengers / cars_driven


print "There are", cars, "cars available."
print "There are only", drivers, "drivers availabe."
print "There will be", cars_not_driven, "empty cars today."
print "We can transport", carpool_capacity, "people today."
print "We have", passengers, "to carpool today."
print "We need to put about", average_passengers_per_car, "in each car."

'''
Test Results:
There are 100 cars available.
There are only 30 drivers availabe.
There will be 70 empty cars today.
We can transport 120.0 people today.
We have 90 to carpool today.
We need to put about 3 in each car.

心得：

1，想起了当年学习C++时，一个有意义的变量名的事情

2，一次全敲对也不容易
