Python any() Function

Python any() function: In this tutorial, we will learn about any() function in Python with its use, syntax, parameters, returns type, and examples. By IncludeHelp April 19, 2024

The any() function is a library function in Python, it is used to check whether any of the elements of an iterable object is True or not. It accepts an iterable object and returns True, if one or more than one elements are True, else it returns False.

If any item in iterable object (eg. list, tuple and dictionary) is true then any() function returns True otherwise False.

If iterable object is empty ( eg. list=[], tuple=()) then any() function returns False.

Syntax

The following is the syntax of any() function:

any(iterable_object)

Parameter(s):

The following are the parameter(s):

• Parameter: iterable_object - An iterable container like list, tuple, dictionary.

Return Value

The return type of any() function is <class 'bool'>, it returns a Boolean value either True or False.

Examples

Example 1: Use of any() function with Python list

if __name__ == "__main__":
    # any() function will return True because 
    # 1st item is true in list_1
    list_1 = [1, 2, 0, 3]
    result = any(list_1)
    print ("list_1: {}".format(result))
    
    # any() function will return False because 
    # none of the items are true in list_2
    list_2 = [0, False, '', 0.0, [], {}, None]
    result = any(list_2)
    print ("list_2: {}".format(result))
    
    # any() function will return False because 
    # list_3 is empty
    list_3 = []
    result = any(list_3)
    print ("list_3: {}".format(result))

Output

list_1: True
list_2: False
list_3: False

Example 2: Use of any() function with Python string

if __name__ == "__main__":
    # any() function will return True because 
    # string_1 is not none
    string_1 = "Hello! python"
    print ("string_1: {}".format(any(string_1)))
    
    # any() function will return True because 
    # string_2 is not none. Here, '0' is True and 0 is false
    string_2 = "0"
    print ("string_2: {}".format(any(string_2)))
    
    # any() function will return False because 
    # string_3 is none
    string_3 = ""
    print ("string_3: {}".format(any(string_3)))

Output

string_1: True
string_2: True
string_3: False

Example 3: Use of any() function with Python dictionary

In case of dictionaries, If all keys are false, any() returns False. If atleast one key is true, any() returns True.

if __name__ == "__main__":
    # any() function will return False because 
    # key in dictonary_1 is False.
    dictonary_1 = {0: 'False'}
    print("dictonary_1: {}".format(any(dictonary_1)))
    
    # any() function will return True because 
    # second key(i.e 1) in dictonary_2 is True.
    dictonary_2 = {0: 'False', 1: 'True'}
    print("dictonary_2: {}".format(any(dictonary_2)))
    
    # any() function will return False because 
    # all keys in dictonary_3 is False.
    dictonary_3 = {0: 'False', False: 0}
    print("dictonary_3: {}".format(any(dictonary_3)))
    
    # any() function will return False because 
    # dictonary_4 is empty.
    dictonary_4 = {}
    print("dictonary_4: {}".format(any(dictonary_4)))
    
    # any() function will return True because 
    # key(i.e '0') in dictonary_5 is True.
    # 0 is False
    # '0' is True
    dictonary_5 = {'0': 'False'}
    print("dictonary_5: {}".format(any(dictonary_5)))

Output

dictonary_1: False
dictonary_2: True
dictonary_3: False
dictonary_4: False
dictonary_5: True

Example 4: Use of any() function with Python tuple

if __name__ == "__main__":
    # any() function will return True because 
    # 1st item in tuple_1 is True.
    tuple_1 = (1, "BeginnersBook", 22)
    print("tuple_1: {}".format(any(tuple_1)))
    
    # any() function will return False because 
    # all items in tuple_2 is False.
    tuple_2 = (0, False, 0)
    print("tuple_2: {}".format(any(tuple_2)))
    
    # any() function will return True because 
    # 1st item in tuple_3 is True.
    tuple_3 = (1, 0, False)
    print("tuple_3: {}".format(any(tuple_3)))
    
    # any() function will return True because 
    # 2nd item in tuple_4 is True.
    tuple_4 = (False, 1, 2, 3)
    print("tuple_4: {}".format(any(tuple_4)))
    
    # any() function will return False because 
    # tuple_5 is empty.
    tuple_5 = ()
    print("tuple_5: {}".format(any(tuple_5)))   

Output

tuple_1: True
tuple_2: False
tuple_3: True
tuple_4: True
tuple_5: False
