                有個方法可以從列表中按給定的索引而不是值來刪除一個子項:?del?語句。它不同于有返回值的pop()?方法。語句?del?還可以從列表中刪除切片或清空整個列表(我們以前介紹過一個方法是將空列表賦值給列表的切片)。例如: ~~~ >>> a = [-1, 1, 66.25, 333, 333, 1234.5] >>> del a[0] >>> a [1, 66.25, 333, 333, 1234.5] >>> del a[2:4] >>> a [1, 66.25, 1234.5] >>> del a[:] >>> a [] ~~~ del?也可以刪除整個變量: `>>> del a` 此后再引用命名?a?會引發錯誤(直到另一個值賦給它為止)。我們在后面的內容中可以看到?del的其它用法。
