Khushi....? ??‍? 5 years ago

Persistence is "the continuance of an effect after its cause is removed". In the context of storing data in a computer system, this means that the data survives after the process with which it was created has ended. In other words, for a data store to be considered persistent, it must write to non-volatile storage.

Enclosing (or nonlocal) scope is a special scope that only exists for nested functions. If the local scope is an inner or nested function, then the enclosing scope is the scope of the outer or enclosing function. ... This Python scope contains all of the names that you define at the top level of a program or a module.

What are local and global scope of variables?

Posted by Khushi....? ??‍? 5 years, 1 month ago

CBSE > Class 12 > Computer Science

1 answers

Yogita Ingle 5 years, 1 month ago

A local variable is a type of variable declared within programming block or subroutines. It can only be used only inside that subroutine or code block in which they were declared. The local variable exists until the block of the function is in under execution. After that, it will be destroyed automatically.

Global variables are defined outside of a subroutine or function. The global variable will hold its value throughout the lifetime of a program. They can be accessed within any function defined for the program.

Meghna Thapar 5 years, 1 month ago

A Python library is a reusable chunk of code that you may want to include in your programs/ projects. Compared to languages like C++ or C, a Python libraries do not pertain to any specific context in Python. Here, a 'library' loosely describes a collection of core modules. A module can be imported by another program to make use of its functionality. This is how you can use the Python standard library as well. Simply put, a module is a file consisting of Python code. It can define functions, classes, and variables, and can also include runnable code.

Explain significance of super() function

Posted by Kumkum Pal 5 years, 1 month ago

CBSE > Class 12 > Computer Science

1 answers

Meghna Thapar 5 years, 1 month ago

The super() function in Python makes class inheritance more manageable and extensible. The function returns a temporary object that allows reference to a parent class by the keyword super. The super() function has two major use cases: To avoid the usage of the super (parent) class explicitly. The super keyword refers to superclass (parent) objects. It is used to call superclass methods, and to access the superclass constructor. The most common use of the super keyword is to eliminate the confusion between superclasses and subclasses that have methods with the same name.
