我正在尝试运行此代码以查找不使用直接公式的复利，并且我不确定为什么会收到此错误“ compound_interest（）接受0个位置参数，但给出了1个”
我只是想将其用作功能。
def CI(Principle):
interest = Principle*Rate
return interest
return New
Principle = 100
Rate = 0.05
Period = 2
New = 0
m = compound_interest(Period)
def compound_interest(Period):
while Period >0:
Interest = CI(Principle)
Principle = Principle + Interest
Period = Period -1
New = Interest + New
return New
print(New)
