What is __ le __ in Python?

Python internally calls x. __le__(y) to obtain a return value when comparing two objects using x <= y . The return value can be any data type because any value can automatically converted to a Boolean by using the bool() built-in function.

What are __ __ methods in Python?

__enter__ and __exit__ magic methods

__enter__ and __exit__ methods are used along with the 'with' block in python. The 'with' block in python is used to open and close the file object or any other objects that have a close method.

What does the __ add __ () do in Python?

Python __add__() function is one of the magic methods in Python that returns a new object(third) i.e. the addition of the other two objects. It implements the addition operator “+” in Python.

What is __ GE __?

The __ge__ method is the magical method that gets invoked when the >= operator is used and it returns True or False. The built-in str() function returns a string from the object parameter and it internally calls the __str__() method defined in the int class.

Is __ init __ a constructor?

The special method __init__ is the Python constructor. With an understanding of object oriented programming and classes, let's now look at how the __init__ method works within a Python program.

What is Le operator?

LE is the relational operator LESS THAN OR EQUAL TO, used in selection expressions to compare an attribute to a constant or to another attribute.

What does __ name __ means?

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 __ Super __ Python?

Definition and Usage. The super() function is used to give access to methods and properties of a parent or sibling class. The super() function returns an object that represents the parent class.

What is __ int __ in Python?

The __int__ method is called to implement the built-in int function. The __index__ method implements type conversion to an int when the object is used in a slice expression and the built-in hex , oct , and bin functions.

Why is __ name __ used in Python?

__name__ is a built-in variable which evaluates to the name of the current module. Thus it can be used to check whether the current script is being run on its own or being imported somewhere else by combining it with if statement, as shown below.

Is __ init __ a magic method?

These are commonly used for operator overloading. Few examples for magic methods are: __init__, __add__, __len__, __repr__ etc.

What is __ index __ method?

__index__ Converts a zero-dimensional integer array to a Python int object. This method is called to implement operator. index().

What is __ eq __ and __ hash __ in Python?

__eq__ and __hash__ must agree - equal objects must have equal hashes. __hash__ must never change. The hash of an object is never re-computed once it is inserted. Objects that implement logical equality (e.g. implement __eq__ ) must be immutable to be hashable.

Why is __ name __ used in Python?

__name__ is a built-in variable which evaluates to the name of the current module. Thus it can be used to check whether the current script is being run on its own or being imported somewhere else by combining it with if statement, as shown below.

How do you use Le in Python?

le() function is a library function of operator module, it is used to perform "less than or equal to operation" on two values and returns True if the first value is less than or equal to the second value, False, otherwise. Parameter(s): x,y – values to be compared.

What does __ name __ == '__ main __' mean?

In Short: It Allows You to Execute Code When the File Runs as a Script, but Not When It's Imported as a Module. For most practical purposes, you can think of the conditional block that you open with if __name__ == "__main__" as a way to store code that should only run when your file is executed as a script.

What is __ name == '__ main __' in Python?

In Python, the special name __main__ is used for two important constructs: the name of the top-level environment of the program, which can be checked using the __name__ == '__main__' expression; and. the __main__.py file in Python packages.

What is __ name __ and __ main __ in Python?

What does the if __name__ == “__main__”: do? Before executing code, Python interpreter reads source file and define few special variables/global variables. If the python interpreter is running that module (the source file) as the main program, it sets the special __name__ variable to have a value “__main__”.

Why is Le used?
