我正在学习python，我正在挑战自己编写一个小程序，询问用户汽车的基本价格，然后将基本价格保存到一个名为base的变量中。它还有两个称为tax和license的变量，它们是百分比。所以它得到基价，得到seven (7)价格的base百分比，并将其添加到基价中。对于许可费等也一样。
不过，我想知道的是，当它运行时：print "\nAfter taxes the price is: ", (base * tax / 100 + base)
如何将结果保存到另一个变量，以便下一行不必编写：
重写它感觉很多余，就像我在浪费时间计算已经计算过的东西。
我想将第一行print "\nAfter taxes and license fee the price is: ", (base*tax / 100)+(base*license /100) + base?的结果保存到一个名为print的变量中，这样我就可以编写：after_tax
（我希望第一个print "\nAfter taxes and license fee the price is: ", after_tax + (base*license /100)命令也将数学计算的结果保存到一个名为print的变量中，这样我就可以重用结果，而不必重新键入整个计算以再次获得结果）。
以下是完整的代码：
#Car salesman calculations program.
base = int(raw_input("What is the base price of the car?" + "\n"))
tax = 7
license = 4
dealer_prep = 500
destination_charge = 1000
print "\nAfter taxes the price is: ", (base * tax / 100 + base)
print "\nAfter taxes and license fee the price is: ", (base*tax / 100)+(base*license /100) + base
print "\nAfter taxes and license fee and dealer prep the price is: ", (base*tax / 100)+(base*license /100) + base + dealer_prep
print "\nAfter taxes, license fees, dealer prep, and destination charge, the total price is: ", (base*tax / 100)+(base*license /100) + base + dealer_prep + destination_charge
raw_input("\nPress the enter key to close the window.")
最佳答案
你可以提前做所有的计算。我建议给变量（a、b、c等）起一个比我在这里更聪明的名字，但这足够说明问题了。
a = (base * tax / 100)
b = (base*license /100)
c = a + b + base
d = c + dealer_prep
e = d + destination_charge
print "\nAfter taxes the price is: ", a + base
print "\nAfter taxes and license fee the price is: ", c
print "\nAfter taxes and license fee and dealer prep the price is: ", d
print "\nAfter taxes, license fees, dealer prep, and destination charge, the total price is: ", e
raw_input("\nPress the enter key to close the window.")
