while循环和布尔

不理解如何让循环停止和继续/重复也，不明白如何让布尔的第二部分工作while循环和布尔

monthly_investment = float(input("Enter monthly investment:\t")) 
while monthly_investment < 1: 
    print("Entry must be greater than 0") 

yearly_interest_rate = float(input("Enter yearly interest rate:\t")) 
while yearly_interest_rate < 1 and yearly_interest_rate < 16: 
    print("Entry must be greater than 0 and less than or equal to 15")

我理解的循环只是没怎么回去，如果该值是Ø – Nimkora

回去的地方？如果您想根据条件进行操作，请使用if语句 –

Nimkora，

你只需要在while循环结束时添加另一个赋值语句，以便用户输入一个有效的输入时，程序可以跳出while循环。

monthly_investment = float(input("Enter monthly investment:\t")) 
while monthly_investment < 1: 
    print("Entry must be greater than 0") 
    monthly_investment = float(input("Enter monthly investment:\t")) 

yearly_interest_rate = float(input("Enter yearly interest rate:\t")) 
while yearly_interest_rate < 1 and yearly_interest_rate < 16: 
    print("Entry must be greater than 0 and less than or equal to 15") 
    yearly_interest_rate = float(input("Enter yearly interest rate:\t"))
