如果一个函数在内部调用自身本身,这个函数就是递归函数。 【例子】设置递归的层数,Python默认递归层数为 100 import sys sys.setrecursionlimit(1000) 1. 2. 3. Lambda 表达式 匿名函数的定义 在Python 里有两类函数: 第一类:用def关键词定义的正规函数 第二类:用lambda关键词定义的匿名函数 Python 使用lambda关键...

Date objects have year, month and day fields. They can be used to get more specific information about the date.print(date_1.year, date_1.month, date_1.day) print(date_2.year, date_2.month, date_2.day) # 1991 10 20 # 2001 6 15...
Reading time: 1 minute To get the current year in Python, you can use thedatetimemodule’sdatetimeclass to create an object that stores the current datetime. After that, you can access theyearproperty from the datetime object as follows: fromdatetimeimportdatetimecurrent_date=datetime.now()print...

This article will explore various methods to extract the current year from a date in Java, ranging from modern solutions like the java.time.LocalDate class to traditional options like java.util.Calendar and even unconventional approaches such as using St
