如何使用 Python 找到指定年份的第一天?
在本程序中,我们必须打印年份的第一天。我们必须根据用户输入获取年份。
算法
Step 1: Import the datetime library. Step 2: Take year as input from the user. Step 3: Get the first day of the year by passing month, day and year as parameters to the datetime.datetime() function Step 4: Display the first day using strftime() function.
示例代码
import datetime year = int(input("Enter year: ")) firstday = datetime.datetime(year, 1,1) print("First Day of ", year, " = ", firstday.strftime("%A"))
输出
First Day of 2021 = Friday
