在遇到Python中用户输入的sum后结束程序

这将提供无限量的求和，但我想在用户输入之前停止求和。您只需比较while循环的条件语句中的两个值，如下所示：

total = 0
not_total = True
sum_of_square = int(input("Enter desired sum: "))

while (not_total == True):
        for n in range (2): 
        total = total + n**2
        print("The sum of squares from 1^2 to {0}^2 is equal to {1}.".format(n,total))

我尝试了那段代码，但它作为一个无限循环返回，但我尝试了这样一个if语句。。。total=0 not_total=True sum_of_square=intinpunter期望的和：而not_total==True:对于范围1100中的n，1:total=total+n**2如果totaltotal = 0 sum_of_square = int(input("Enter desired sum: ")) while (sum_of_squares <= total): for n in range (2): total = total + n**2 print("The sum of squares from 1^2 to {0}^2 is equal to {1}.".format(n,total))
