There is a way to remove an item from a list given its index instead of its value: the del statement. This can also be used to remove slices from a list (which we did earlier by assignment of an empty list to the slice). For example:
>>> a [-1, 1, 66.6, 333, 333, 1234.5] >>> del a >>> a [1, 66.6, 333, 333, 1234.5] >>> del a[2:4] >>> a [1, 66.6, 1234.5]
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.
