Question

我有以下内容应该返回一个感兴趣的值，它应该除以100.我该如何实现呢？

import math

p = int(raw_input("Please enter deposit amount: \n"))
r = float(raw_input("Please input interest rate: \n")) /100
t = int(raw_input("Please insert number of years of the investment: \n"))
interest = raw_input("Do you want a simple or compound interest ? \n")

A = p*(1+r*t) 
B = p*(1+r)^t 

if interest == "simple":
print (float(A))
else:
print(float(B))

Answer 1

尝试这样的事情（提示您不需要import math这样的事情）：

from decimal import *

p = Decimal(raw_input("Please enter deposit amount:"))
r = Decimal(raw_input("Please input interest rate as a percentage:")) /100
t = int(raw_input("Please insert number of years of the investment:"))
n = 1 # You should really be asking how many times is the interest compounded per year? If the user chooses compound...

A = p*(1 + r)**t
B = p*(1 + r)**(n*t)

while(True):
  interest = raw_input("Do you want simple or compound interest?")
  if(interest.lower() == "simple"):
    print(A)
    break
  elif(interest.lower() == "compound"):
    print(B)
    break
