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 values l = [False, False, True, False, False] print(any(l))
Output:
True
Python any() Function Lists
In this example, the any() function is used to check if any value in the list is True. If at least one element in the Python list is True, it will return 'True'; otherwise, it will return 'False'. Additionally, there is a step to check if all elements in List meet condition in Python. This is achieved using the all() function itself.
Python3 # All elements of list are True l = [4, 5, 1] print(any(l)) # All elements of list are False l = [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 list l = [] print(any(l))
Output:
True
False
False
Working of any() Function with Tuples
In this example, we will see the use of the any() function on Python Tuples, providing a way to check if any value is true in a tuple. By using any() we can Check if all items in a list are True. 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 True t = (2, 4, 6) print(any(t)) # All elements of tuple are False t = (0, False, False) print(any(t)) # Some elements of tuple are True while # others are False t = (5, 0, 3, 1, False) print(any(t)) # Empty tuple t = () print(any(t))
Output:
True
False
True
False
Working of any() Function with Sets
In this example, we will see the use of the any() function on Python Sets, demonstrating how it can be used to check if any value is true in a set. 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 True s = { 1, 1, 3} print(any(s)) # All elements of set are False s = { 0, 0, False} print(any(s)) # Some elements of set are True while others are False s = { 1, 2, 0, 8, False} print(any(s)) # Empty set s = {} 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 true d = {1: "Hello", 2: "Hi"} print(any(d)) # All keys of dictionary are false d = {0: "Hello", False: "Hi"} print(any(d)) # Some keys of dictionary # are true while others are false d = {0: "Salut", 1: "Hello", 2: "Hi"} print(any(d)) # Empty dictionary d = {} 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. This usage of the any() function allows you to check if any value is true in a string, effectively determining whether the string is empty or not.
Python3 # Non-Empty String s = "Hi There!" print(any(s)) # Non-Empty String s = "000" print(any(s)) # Empty string s = "" 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. This function is particularly useful to check if all/any elements in List meet condition in Python. It provides a convenient way to determine if at least one element in an iterable is true.
Python3 # Python3 code to demonstrate working of any() # To Check if any element in list satisfies a condition # initializing list test_list = [4, 5, 8, 9, 10, 17] # printing list print("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 result print("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 and to check if all elements in List are True. 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() function def my_any(list_x): for item in list_x: if item: return True return False x = [4, 5, 8, 9, 10, 17] print(my_any(x))
Output:
True
