The most common approach to check if a number is even or odd in Python is using themodulo operator (%). The modulo operator returns the remainder after division. An even number is evenly divisible by 2 with no remainder, while an odd number leaves a remainder of 1 when divided by 2. ...

def check_even_or_odd(number): if number % 2 == 0: print(number, “是偶数”) else: print(number, “是奇数”) check_even_or_odd(7) # 输出:7 是奇数 check_even_or_odd(12) # 输出:12 是偶数 “` 上述代码定义了一个`check_even_or_odd`函数,它接受一个参数`number`表示要判断的数字。
除了使用if-else结构外,我们还可以使用多个if语句来执行多个代码块。在这种情况下,每个if语句都会独立判断条件,并执行与其关联的代码块。 number=15ifnumber>10:print("Number is greater than 10")print("This is the second line of code in the first if block")ifnumber%2==0:print("Number is even")...

numbers=[2,4,6,8,1]fornumberinnumbers:ifnumber%2==1:print(number)breakelse:print("No odd numbers") 如果找到了奇数,就会打印该数值,并且执行break语句,跳过else语句。没有的话,就不会执行break语句,而是执行else语句。 ▍2、从列表中获取元素,定义多个变量 ...

if a method is called with the wrong number of arguments, an exception will be raised. This is extremely important as refactors happen. As a library changes, tests break and that is expected. Without using an auto-spec, our tests will still pass even though the underlying implementation is...
