我一直在 Python 上收到錯誤消息，TypeError: unsupported operand type(s) for /: 'tuple' and 'int' 我做錯了什么？

Question

復利計算器

＃輸入

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? ") )

＃計算

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

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

＃輸出

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

Answer 1

正確語法：

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

Answer 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"))應該像float(input("bla bla bla")))和int, input("bla bla bla"))把它改成這樣： int(input("bla bla bla"))
