Python any() function returns True if any of the elements of a given iterable( List, Dictionary, Tuple, set, etc) are True else it returns False.
Example
Input: [True, False, False] Output: True Input: [False, False, False] Output: False
Python any() Function Syntax
any() function in Python has the following syntax:
Syntax: any(iterable)
- Iterable: It is an iterable object such as a dictionary, tuple, list, set, etc.
Returns: Returns True if any of the items is True.
Python any() Function Example
Python any() Function on Lists in Python. The below example returns True since at least one element in the list (3rd element) is True.
Python3
# a List of boolean valuesl = [False, False, True, False, False]print(any(l)) |
Output:
True
Python any() Function Lists
This example demonstrates the use of any() on Python Lists. If at least a single element in the list is True, the any() function will return ‘True’ else it will return ‘False’.
Python3
# All elements of list are Truel = [4, 5, 1]print(any(l))# All elements of list are Falsel = [0, 0, False]print(any(l))# Some elements of list are# True while others are False# l = [1, 0, 6, 7, False]# print(any(l))# Empty listl = []print(any(l)) |
Output:
True False False
Working of any() Function with Tuples
In this example, we will see the use of any() function on Python Tuples. If at least a single element in the tuple is True, the any() function will return ‘True’ else it will return ‘False’ even if the tuple is empty.
Python3
# All elements of tuple are Truet = (2, 4, 6)print(any(t))# All elements of tuple are Falset = (0, False, False)print(any(t))# Some elements of tuple are True while# others are Falset = (5, 0, 3, 1, False)print(any(t))# Empty tuplet = ()print(any(t)) |
Output:
True False True False
Working of any() Function with Sets
In this example, we will see the use of any() function on Python Sets. The any() function on sets acts similarly as it is for a list or a tuple. If at least a single element in a set evaluates to be ‘True’, it will return ‘True’.
Python3
# All elements of set are Trues = { 1, 1, 3}print(any(s))# All elements of set are Falses = { 0, 0, False}print(any(s))# Some elements of set are True while others are Falses = { 1, 2, 0, 8, False}print(any(s))# Empty sets = {}print(any(s)) |
Output:
True False True False
Working of any() function with Dictionaries
In the case of a dictionary, if all the keys of the dictionary are false or the dictionary is empty, any() function in Python returns False. If at least one key is True, any() returns True.
Python3
# All keys of dictionary are trued = {1: "Hello", 2: "Hi"}print(any(d))# All keys of dictionary are falsed = {0: "Hello", False: "Hi"}print(any(d))# Some keys of dictionary# are true while others are falsed = {0: "Salut", 1: "Hello", 2: "Hi"}print(any(d))# Empty dictionaryd = {}print(any(d)) |
Output:
True False True False
Working of any() function with Strings
In this example, we will see how Python any() function works with Python String. The any() function returns True, if there is at least 1 character in the string.
Python3
# Non-Empty Strings = "Hi There!"print(any(s))# Non-Empty Strings = "000"print(any(s))# Empty strings = ""print(any(s)) |
Output:
True True False
Python any() Function with a Condition
In this example, the any() function in Python checks for any element satisfying a condition and returns True in case it finds any True value.
Python3
# Python3 code to demonstrate working of any()# To Check if any element in list satisfies a condition# initializing listtest_list = [4, 5, 8, 9, 10, 17]# printing listprint("The original list : ", test_list)# Check if any element in list satisfies a condition# Using any()res = any(ele > 10 for ele in test_list)# Printing resultprint("Does any element satisfy specified condition ? : ", res) |
Output:
The original list : [4, 5, 8, 9, 10, 17] Does any element satisfy specified condition ? : True
Python any() Function with For Loop
In this example, we will implement any() function using Python functions and a for loop. The my_any() function returns True if any element of the iterable is True, else returns False.
Python3
# this function gives same result as built-in any() functiondef my_any(list_x): for item in list_x: if item: return True return Falsex = [4, 5, 8, 9, 10, 17]print(my_any(x)) |
Output:
True
