5.2 The del statement

There is a way to remove an item from a list given its index instead of its value: the del statement. This differs from the pop() method which returns a value. The del statement can also be used to remove slices from a list or clear the entire list (which we did earlier by assignment of an empty list to the slice). For example:

>>> 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 can also be used to delete entire variables:

>>> del a

Referencing the name a hereafter is an error (at least until another value is assigned to it). We'll find other uses for del later
