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.

Python any() Function 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 the atleast 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

Example 1: Python any()  function Lists

Use of any() on Python Lists.

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
True
False

Example 2: Working of any() function with Tuples

Use of any() function on Python Tuples.

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

Example 3: Working of any() function with Sets

Use of any() function on Python Sets.

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

Example 4: Working of any() function with Dictionaries

Note: In the case of a dictionary if all the keys of the dictionary are false or the dictionary is empty the any() 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

Example 5: Working of any() function with Strings

Python any() returns True, if there is atleast 1 character in the string.

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

Example 6: Python any function with condition

It 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 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

Example 7: Python any() function with for loop

Implementing any() function using Python function and for-loop. 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
