Python any()

ItsMyCode |

The any() function in Python returns True if any element of an iterable( List , set , dictionary , tuple ) is True. If not, it returns False.

any() Syntax

The syntax of any() method is

any(iterable)

any() Parameters

The any() function takes iterable as an argument the iterable can be of type list , set , tuple , dictionary , etc.

any() Return Value

The any() method returns a boolean value.

• True if one of the elements in iterable is true
• False if all the elements in iterable are false or if the iterable is empty

Condition	Return Value
All elements are true	True
All elements are false	False
One element is true and others are false)	True
One element is false and others are true	True
Empty Iterable	False

Example 1 – Using any() function on Python Lists

# All the elements in the list are true
list = [1,3,5,7]
print(any(list))

# All the elements in the list are false
list = [0,0,False]
print(any(list))

# Some of the elements are false
list = [1,5,7,False]
print(any(list))

# Only 1 element is true
list = [0, False, 5]
print(any(list))

# False since its Empty iterable 
list = []
print(any(list))

Output

True
False
True
True
False

Example 2 – Using any() function on Python Strings

# Non Empty string returns True
string = "Hello World"
print(any(string))

# 0 is False but the string character of 0 is True 
string = '000'
print(any(string))

# False since empty string and not iterable
string = ''
print(any(string))

Output

True
True
False

Example 3 – Using any() function on Python Dictionaries

In the case of a dictionary, only if all the keys( not values ) of the dictionary are either false or if the dictionary is empty, the any() method returns False. If at least one key is true, then any() returns True.

# All elements in dictionary are true
dict = {1: 'Hello', 2: 'World'}
print(any(dict))

# All elements in dictionary are false
dict = {0: 'Hello', False: 'World'}
print(any(dict))

# Some elements in dictionary are true and rest are false
dict = {0: 'Hello', 1: 'World', False: 'Welcome'}
print(any(dict))

# Empty Dictionary returns false
dict = {}
print(any(dict))

Output

True
False
True
False

Example 4 – Using any() function on Python Tuples

# All elements of tuple are true
t = (1, 2, 3, 4)
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 returns false
t = ()
print(any(t))

Output

True
False
True
False

Example 5 – Using any() function on Python Sets

# All elements of set are true
s = {1, 2, 3, 4}
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, 3, 0, False}
print(any(s))

# Empty set returns false
s = {}
print(any(s))

Output

True
False
True
False
