. We don't know or we are not sure about the index of the value 32, but we need to delete it. Python array has the built in function remove. For example
Angular services are used to organize code across the application and are wired together using Dependancy Injection. Angular services are lazily instantiated, i.e, they are instantiated only when an application component depends on it.They are singletons, ie there will be only one instance exists for the app and the components depending on the service gets the reference to the service.
Perl is an object oriented language. Perl has packages(class) that could be instanciated and used. At first, we need to decide the file namefor the package ans the perl class name carries the file name. For example, a package Student
should be in the file Student.pm
. If it shouldbe called Bright::Student
, it should be saved asBright/Student.pm
, ie Student.pm
in a directory named Bright
. There is no formal relationship between directory name and modules. That is just grouping for convenience.
