=“运算符和"and"逻辑运算符来判断a是否不等于b和c。只有当a不等于b且不等于c时,才会输出"a is not equal to b and c”。 使用in关键字判断不等于多个数 除了使用逻辑运算符"and"来判断一个数是否不等于多个数外,我们还可以使用in关键字来实现类似的功能。 a=10b=20c=30ifanotin[b,c]:print("a is...

请注意,"if not x:"语句只检查x是否为假值(如0、False、None、空字符串等),而不会检查x是否具有其中一种特定类型的值。如果您想检查x是否为一些特定值,可以使用等于(==)运算符。例如: ```python x = "Hello" if x == "Hello": print("x is equal to Hello") else: print("x is not equal to...
