python - 我将如何舍入代码的输出？

问题描述

我是编程新手（昨天刚开始），我试图制作一个计算器，当给定变量输入时，它会得出数字。它工作得很好，但我想这样做，以便代码最后的输出被四舍五入。我将如何舍入代码的输出？

print("What is the Initial Principal Value?")

P = int(input())
print("What is the interest rate?")
r = float(input())

print("What is the number of times interest is applied per time period")
n = int(input())

print("Finally, what is the number of time periods elapsed, this must be typed in terms of annual circumstances.")
t = int(input())
      
print(P*(1+(r/n))**(n/t))

round()

解决方案

Here it is:

print("What is the Initial Principal Value?")

P = int(input())
print("What is the interest rate?")
r = float(input())

print("What is the number of times interest is applied per time period")
n = int(input())

print("Finally, what is the number of time periods elapsed, this must be typed in terms of annual circumstances.")
t = int(input())

result = round(P * (1 + (r / n)) ** (n / t), 2)
print(result)
