Question

正在将垃圾值发送到函数，而不是实际参数。我的代码有什么问题？

def find_leap_years(given_year):
    i=0
    count=0
    while(count<15):
        print(given_year)
        if(given_year%4==0)and(given_year%400==0):
            if(given_year%100!=0):
                list_of_leap_years[i]=given_year
                i+=1
                count+=1
        given_year+=1

    return list_of_leap_years

list_of_leap_years=find_leap_years(2000)
print(list_of_leap_years)

Answer 1

list_of_leap_years未在函数内部声明，因此它从外部范围获取值，例如，可能未定义。

Answer 2

您的目标是这样吗？您的问题和代码不清楚您要实现的目标，但是如果这是您的目标，那么我可以解释一下我认为您的代码出了什么问题。

def find_leap_years(given_year):
    list_of_leap_years = []
    for i in range(given_year + 1): 
        if i%4 == 0:
            if i%100 == 0:
                if i%400 == 0:
                    list_of_leap_years.append(i)
                else:
                    continue
            else:
                list_of_leap_years.append(i)
        else:
            continue
    return list_of_leap_years

leap_years = find_leap_years(2000)
print(leap_years)

输出
