Python any() function
Last Updated :
17 Nov, 2023
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
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
l = [4, 5, 1]
print(any(l))
l = [0, 0, False]
print(any(l))
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
t = (2, 4, 6)
print(any(t))
t = (0, False, False)
print(any(t))
t = (5, 0, 3, 1, False)
print(any(t))
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
s = { 1, 1, 3}
print(any(s))
s = { 0, 0, False}
print(any(s))
s = { 1, 2, 0, 8, False}
print(any(s))
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
d = {1: "Hello", 2: "Hi"}
print(any(d))
d = {0: "Hello", False: "Hi"}
print(any(d))
d = {0: "Salut", 1: "Hello", 2: "Hi"}
print(any(d))
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
s = "Hi There!"
print(any(s))
s = "000"
print(any(s))
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
test_list = [4, 5, 8, 9, 10, 17]
print("The original list : ", test_list)
res = any(ele > 10 for ele in test_list)
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
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
