实现__getitem__足以允许按索引检索项目,并支持迭代和in运算符。__getitem__特殊方法实际上是序列协议的关键。查看Python/C API 参考手册中的这篇文章,“序列协议”部分。int PySequence_Check(PyObject *o)如果对象提供序列协议,则返回1,否则返回0。请注意,对于具有__getitem__()方法的 Python 类,除非它们是...
continue语句单独使用continue关键字,不带任何参数。我们在while或for循环中使用continue语句。当一条continue语句执行时,程序执行立即跳转到下一次迭代的循环开始处。当程序执行到循环块的末尾时,也会发生这种情况。但是一个continue语句使得程序执行在到达循环结束之前跳回到循环的开始。
input_float = input() # Type in: 3.142 input_boolean = input() # Type in: True # Convert inputs into other data types convert_float = float(input_float) # converts the string data type to a float convert_boolean = bool(input_boolean) # converts the string data type to a bool ...
In the above example, you use the %s combination of characters as a conversion specifier. The % symbol marks the start of the specifier, while the s letter is the conversion type and tells the operator that you want to convert the input object into a string....
