Question

我制作了一个打印每年日期的程序。是否可以添加一个允许限制可打印日期的计数器？我会每隔7天打印一次。谢谢你的建议。以下原始代码。

def main():

    for month in range(1, 13):
        daymax = 32
        if month == 2:
            daymax = 29
        elif month == 4:
            daymax = 31
        elif month == 6:
            daymax = 31
        elif month == 9:
            daymax = 31
        elif month == 11:
            daymax = 31

        for day in range(1, daymax):
            print(day,".", month,".", sep="")


main()

Answer 1

只需使用另一个计数器变量，并检查它是否是7的倍数。

def main():
    counter = 0
    for month in range(1, 13):
        daymax = 32
        if month == 2:
            daymax = 29
        elif month == 4:
            daymax = 31
        elif month == 6:
            daymax = 31
        elif month == 9:
            daymax = 31
        elif month == 11:
            daymax = 31

        for day in range(1, daymax):
            if counter % 7 == 0:
                print(day,".", month,".", sep="")
            counter += 1
