Python any() function

Last Updated : 26 Nov, 2020

The any() function is an inbuilt function in Python which returns true if any of the elements of a given iterable( List, Dictionary, Tuple, set, etc) are True else it returns False.

Syntax: any(iterable)

Parameters: Iterable: It is an iterable object such as a dictionary, tuple, list, set, etc.

Example #1: Working of any() with 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() with 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() with 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() 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 elements of dictionary are true
d = {1: "Hello", 2: "Hi"}
print(any(d))
  
# All elements of dictionary are false
d = {0: "Hello", False: "Hi"}
print(any(d))
  
# Some elements 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() with Strings.

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
