寫一個函數，在給定的年數后，用給定的初始余額和利率計算銀行帳戶的余額。假設利息每年復利。在

出現錯誤“ValueError:索引28處不支持格式字符"I"（0x49）”

這是我目前為止的代碼。在def BankBalance():

InputB = 1000

return InputB

print("Your initial balance is $1000")

def Interest():

InputI = 0.05

return InputI

print("The rate of interest is 5%")

def CountNumber():

InputN = float(input("Please enter the number of times per year you would like your interest to be compounded: "))

return InputN

def Time():

InputT = float(input("Please enter the number of years you need to compund interest for:"))

return InputT

def Compount_Interest(InputB, InputI, InputT, InputN):

Cinterest = (InputB*(1+(InputI % InputN))**(InputN * InputT))

print("The compound interest for %.InputT years is %.Cinterest" %Cinterest)

B = BankBalance()

I = Interest()

N = CountNumber()

T = Time()

Compount_Interest(B, I, N, T)
