想要在 python 中显示月份名称和闰年

Question

程序应提示用户输入月份和年份（作为整数）并显示该月的天数以及月份名称。例如，如果用户输入 2 月和 2000 年，程序应显示：Enter a month as an integer (1-12): 2Enter a year: 2000There are 29 days in February of 2000def numberOfDays(month, year):    daysInMonths = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]    if month > len(daysInMonths) or year < 0 or month < 0:        return "Please enter a valid month/year"    return daysInMonths[month-1] + int((year % 4) == 0 and month == 2)def main():    year = int(input("Enter a year: "))    month = int(input("Enter a month in terms of a number: "))    print(month, year, "has", numberOfDays(month, year) , "days")if __name__ == '__main__':     main()在这个程序中，我想显示月份的名称并将其打印在最后。那么程序会怎样呢？我应该怎么办？例如，如果输入为 1，则 1 应指定为一月并打印。

Answer 1

使用字典：

dict_month = {1:"January", 2: "February"} # and so on ...

print(dict_month.get(month), year, "has", numberOfDays(month, year) , "days")

Answer 2

您可以使用日历模块来完成此任务：

import calendar

months = list(calendar.month_name) #gets the list of months by name

obj = calendar.Calendar()

y, m = int(input('Enter year: ')), int(input('Enter a month as an integer (1-12): '))

days = calendar.monthrange(y, m)[1]

print(f'There are {days} days in {months[m]} of {y}')

如果您只想检查年份是否为闰年：

import calendar

print(calendar.isleap(int(input('Enter year: '))))
