Python any() function usage

Definition and Usage The any() function returns True if any item in an iterable are true, otherwise it returns False. If the iterable object is empty, the any() function will return False.

What is the use of all () and any () in Python?

Introduction to any() and all()

Both functions are equivalent to writing a series of or and and operators respectively between each of the elements of the passed iterable . They are both convenience functions that shorten the code by replacing boilerplate loops.

How do you use any () and all ()?

Similar to any() , all() takes in a list, tuple, set, or any iterable, ​like so:

1. all_true = [True, 1, 'a', object()]
2. one_true = [True, False, False, 0]
3. all_false = [None, '', False, 0]
4. print(all(all_true))
5. print(all(one_true))
6. print(all(all_false))

What is any () in Python?

Any and All are two built ins provided in python used for successive And/Or. Any. Returns true if any of the items is True. It returns False if empty or all are false. Any can be thought of as a sequence of OR operations on the provided iterables.

What happens when we use any () on a list?

The any() function returns a boolean value: True if at least one element of an iterable is true. False if all elements are false or if an iterable is empty.

Is any in Python?

Fortunately, any() in Python is such a tool. It looks through the elements in an iterable and returns a single value indicating whether any element is true in a Boolean context, or truthy.

What is purpose of pass statement in Python?

Python pass Statement

The pass statement is used as a placeholder for future code. When the pass statement is executed, nothing happens, but you avoid getting an error when empty code is not allowed. Empty code is not allowed in loops, function definitions, class definitions, or in if statements.

How does all work Python?

Python all() function accepts an iterable object (such as list, dictionary etc.) as an argument. If all the elements in the passed iterable are true then all() function returns true else it returns false. If the iterable is empty then also this function returns true.

What is the difference between any () and all ()?

"All" means every one of the available choices. "Any" means some subset of the available choices. Depending on context, it may mean just one, or it could mean that more than one is allowed.

What is the difference between the all and any functions?

any will return True when at least one of the elements is Truthy. Read about Truth Value Testing. all will return True only when all the elements are Truthy. Since none of the elements are true, it returns False in this case.

What is zip method in Python?

Python's zip() function is defined as zip(*iterables) . The function takes in iterables as arguments and returns an iterator. This iterator generates a series of tuples containing elements from each iterable. zip() can accept any type of iterable, such as files, lists, tuples, dictionaries, sets, and so on.

What is Python class method?

A class method is a method that is bound to a class rather than its object. It doesn't require creation of a class instance, much like staticmethod. The difference between a static method and a class method is: ... Class method works with the class since its parameter is always the class itself.

How do I use python Doctest?

Here's a simple example:

1. import testmod from doctest to test the function.
2. Define our test function.
3. Provide a suitable docstring containing desired output on certain inputs.
4. Define the logic.
5. Call the testmod function with the name of the function to test and set verbose True as arguments.
