Question

这是我到目前为止的内容，我认为它是完整的，除了输出仅为10,000的事实外，我的错误为零（这是错误的，我使用15年作为“ t”）。我环顾了类似的问题，并遵循了一些建议，但没有任何解决方法。我只想念些愚蠢的东西吗？谢谢！

print ("Hello, this program will calculate compound interest with a rate of 8%, a principal of 10,000 dollars, on a 12 month cycle (where n is 12)")
p = 10000.00
r = .08
n = 12
t = int(input("Please enter the length of time for the interest to be compounded: "))
amount = (p*(1+(r//(100.0*n))**(n*t)))
print ("The final amount is",amount,"for an initial investment of 10,000, with a rate of 8% and compounded monthly over",t,"years.")

Answer 1

正如我的评论中所述，您的代码无法很好地捕获实际公式。正确检查支架。

print ("Hello, this program will calculate compound interest with a rate of 8%, a     principal of 10,000 dollars, on a 12 month cycle (where n is 12)")
p = 10000.00
r = .08
n = 12
t = int(input("Please enter the length of time for the interest to be compounded: "))
amount = p*((1+(r/(100*n)))**(n*t))
print ("The final amount is",amount,"for an initial investment of 10,000, with a rate of 8% and compounded monthly over",t,"years.")

结果：10120.718840552334
