Python List Module Attributes

So in Python, there is a dir() method which can list all functions and attributes of a module. Inside of this dir() function, we specify the module that we would like to see all functions and attributes of.

What are module attributes in Python?

A module is a Python object with arbitrarily named attributes that you can bind and reference. Simply, a module is a file consisting of Python code. A module can define functions, classes and variables. A module can also include runnable code.

How do I see all the functions of a module in Python?

We can list down all the functions present in a Python module by simply using the dir() method in the Python shell or in the command prompt shell.

Which function is used to get all attributes of a module in Python?

__dict__ Attribute dir() is a built-in function that also returns the list of all attributes and functions in a module.

What is __ module __ in Python?

A module in Python is a file (ending in .py ) that contains a set of definitions (variables and functions) that you can use when they are imported. Modules are considered as objects, just as everything else is in Python.

What is __ all __ in Python?

PACKAGES. In the __init__.py file of a package __all__ is a list of strings with the names of public modules or other objects. Those features are available to wildcard imports. As with modules, __all__ customizes the * when wildcard-importing from the package.

What are the 3 modules in Python?

What is the value of module attribute __ name __ equal to Main?

Every Python module has it's __name__ defined and if this is '__main__', it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.

What is __ init __ py?

The __init__.py files are required to make Python treat directories containing the file as packages. This prevents directories with a common name, such as string , unintentionally hiding valid modules that occur later on the module search path.

How do I explore a Python module?

Use the built-in dir() function to interactively explore Python modules and classes from an interpreter session. The help() built-in lets you browse through the documentation right from your interpreter.

What are list functions in Python?

Method	Description
copy()	Returns a copy of the list
count()	Returns the number of elements with the specified value
extend()	Add the elements of a list (or any iterable), to the end of the current list

What is the __ name __ variable?

The __name__ variable (two underscores before and after) is a special Python variable. It gets its value depending on how we execute the containing script. Sometimes you write a script with functions that might be useful in other scripts as well. In Python, you can import that script as a module in another script.

What is __ variable in Python?

The leading double underscore tells the Python interpreter to rewrite the name in order to avoid conflict in a subclass. Interpreter changes variable name with class extension and that feature known as the Mangling.

What is __ slots __?

The __slots__ declaration allows us to explicitly declare data members, causes Python to reserve space for them in memory, and prevents the creation of __dict__ and __weakref__ attributes. It also prevents the creation of any variables that aren't declared in __slots__.

Is __ init __ py necessary?

The __init__.py files are required to make Python treat directories containing the file as packages. This prevents directories with a common name, such as string , unintentionally hiding valid modules that occur later on the module search path.

What is the purpose of __ all __?

The __all__ in Python is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module.

How many types of modules are there in Python?

The Python standard library contains well over 200 modules, although the exact number varies between distributions.
