A namespace is a declarative region that provides a scope to the identifiers (the names of types, functions, variables, etc) inside it. Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially when your code base includes multiple libraries.

How do you define namespace in Python?

Namespace is a way to implement scope. In Python, each package, module, class, function and method function owns a "namespace" in which variable names are resolved. When a function, module or package is evaluated (that is, starts execution), a namespace is created.

Why are namespaces used in Python?

Namespaces help us uniquely identify all the names inside a program. However, this doesn't imply that we can use a variable name anywhere we want. A name also has a scope that defines the parts of the program where you could use that name without using any prefix.

What is namespace give the example?

A file path, which uses syntax defined by the operating system, is considered a namespace. For example, C:\Program Files\Internet Explorer is the namespace that describes where Internet Explorer files on a Windows computer.

What are the namespace level elements?

Elements you can declare at namespace level include classes, structures, modules, interfaces, enumerations, and delegates.

Why do we require a namespace?

Namespaces provide a method for preventing name conflicts in large projects. Symbols declared inside a namespace block are placed in a named scope that prevents them from being mistaken for identically-named symbols in other scopes. Multiple namespace blocks with the same name are allowed.

Is Iostream a namespace?

Explanation: It is known that “std” (abbreviation for the standard) is a namespace whose members are used in the program. So the members of the “std” namespace are cout, cin, endl, etc. This namespace is present in the iostream.

What is a module namespace in Python?

In Python-speak, modules are a namespace—a place where names are created. And names that live in a module are called its attributes. Technically, modules correspond to files, and Python creates a module object to contain all the names defined in the file; but in simple terms, modules are just namespaces.

What are lists in Python?

Lists are used to store multiple items in a single variable. Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.

How many data types are there?

Most modern computer languages recognize five basic categories of data types: Integral, Floating Point, Character, Character String, and composite types, with various specific subtypes defined within each broad category.

What are tuples in Python?

Tuple. Tuples are used to store multiple items in a single variable. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable.

What is iostream and namespace?

How is namespace different from iostream?

IOstream is a library package which support all basic input output operation such as printing data, collecting input from user, creating class, etc. istream is directly associated with keyboard and ostream with monitor. Namespace is a region that provide scope to identifier, function, variable to avoid collision.
