else:return x大于10 上面函数的含义就是，如果参数x的值不大于10，就会返回“x不大于10”，如果参数x的值大于10，就会返回“x大于10”。4、if not还可以用于控制语句，比如在列表中查找某个元素，如果没有找到，可以使用if not语句来控制程序的执行流程。例如：list = [1,2,3,4]if not 3 in list:
# if语句示例lists=['a',1,'b',['c','nanhua'],1]forlistinlists:iflist==1:lists.remove(1)print(lists)# 先理清for循环:遍历lists所有元素# 注意到if语句有缩进:每遍历到一个元素都需要运行一次if语句# if语句含义:判断每次遍历到的元素是否等于1# 注意到if的后一句也存在缩进:如果遍历的元素等于1...
第二种是 `if not x:`; 第三种是`if not x is None`(这句这样理解更清晰`if not (x is None)`) 。 if x is not None`是最好的写法,清晰,不会出现错误,以后坚持使用这种写法。 使用if not x这种写法的前提是:必须清楚x等于None, False, 空字符串"", 0, 空列表[], 空字典{}, 空元组()时...

(1) not与逻辑判断句if连用,代表not后面的表达式为False的时候,执行冒号后面的语句。比如: a =Falseifnot a: (这里因为a是False,所以not a就是True) print"hello" 这里就能够输出结果hello (2) 判断元素是否在列表或者字典中,if a not in b,a是元素,b是列表或字典,这句话的意思是如果a不在列表b中,那...
