Python 我如何舍入代码的输出？

我是编程新手（昨天刚开始），我试着做一个计算器，当输入变量时，它会计算出数字。它工作得很好，但我希望这样做，以便代码最后的输出能够被舍入。我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()

这是：

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)

round（P*（1+（r/n））**（n/t），2）

？您缺少

round（）

中的参数。
