The omnipotent with statement

Iterating plain lists, parsing dictionaries, looping a sequence of numbers, parsing through a path and selectively copying files, or just picking up a random item from a list could be achieved using the "Swiss knife" utility, with statement. The with statements take the following form:

with_xxx

Here, the xxx parameter is the type of data that needs to be looped, for example, items, dictionaries, and so on.

The following table lists the types of data that the with statement can iterate:

Construct	Data type	Description
with_items	Array	This is used to loop array items. For example, this is used to create a group of users, directories, or to install a list of packages.
with_nested	Nested loops	This is used to parse multidimensional arrays. For example, to create a list of MySQL users and grant them access to a group of databases.
with_dict	Hashes	This is used to parse a dictionary of key-value pairs and create virtual hosts.
