复利计算器

#输入

P = (float, input("Enter the starting principal: ") )
R = (float, input("Enter the annual interest rate: ") )
m = (int, input("How many times per year is the interest compounded? ") )
t = (float, input("For how many years will the account earn interest? ") )

#计算

#FV = P * ( 1 + ( (R/100) / m ) ) ** ( m * t)

FV = P * ( 1 + ( (R/100) / m ) ) ** ( m * t)

#输出

print("At the end of ", t, "years. You will have $", format(FV, ",.2f") )

【解决方案1】：

正确的语法：

input_variable = float(input("some text"))
input_variable= int(input("some text"))

哇，我觉得自己很笨，谢谢你，哈哈！天哪，我已经尝试修复它几个小时了，多么简单的修复，非常感谢我不擅长编程仍在努力学习！

【解决方案2】：

P = float(input("Enter the starting principal: ") )
R = float(input("Enter the annual interest rate: ") )
m = int(input("How many times per year is the interest compounded? ") ) )
t = float(input("For how many years will the account earn interest? ") )

FV = P * ( 1 + ( (R/100) / m ) ) ** ( m * t)

print("At the end of ", t, "years. You will have $", format(FV, ",.2f") )

float, input("bla bla bla")) 应该类似于 float(input("bla bla bla"))) 并使用 int, input("bla bla bla")) 将其更改为：int(input("bla bla bla"))
