Python any() Function with examples

Python any() function accepts iterable (list, tuple, dictionary etc.) as an argument and return true if any of the element in iterable is true, else it returns false. If iterable is empty then any() method returns false.

Python any() function example with lists

The any() function returns true if any of the element in the passed list is true. Here we are taking various lists with different items to demonstrate the output of any() function in different situations.

# all values are true
lis1 = [10, 20, 30, 40]
print(any(lis1))

# all values are false
lis2 = [0, False]
print(any(lis2))

# one value is false, others are true
lis3 = [0, 10, 5, 15]
print(any(lis3))

# one value is true, others are false
lis4 = [10, 0, False]
print(any(lis4))

# empty iterable
lis5 = []
print(any(lis5))

Output:

Python any() function example with Dictionaries

The any() function only checks the keys (not values) in the passed dictionary. If any of the key is true in the dictionary then any() function returns true, else it returns false. The any() function returns false for empty dictionary as well.

# all keys are true
dict1 = {1: 'False', 2: 'True'}
print(any(dict1))

# all keys are false
dict2 = {0: 'False', False: 'True'}
print(any(dict2))

# one key is false, other is true
dict3 = {0: 'False', 1: 0}
print(any(dict3))

# One key is true, '0' is not false its True
# because '0' is a string not a number
# if it is 0 without quotes then its false
dict4 = {'0': 'False'}
print(any(dict4))

# empty dictionary
dict5 = {}
print(any(dict5))

Output:

Python any() function example with Tuples

Python any() function returns true if any of the item in tuple is true else it returns false. The any function returns false if the passed tuple is empty.

# all elements are true
t1 = (1, "BeginnersBook", 22)
print(any(t1))

# all elements are false
t2 = (0, False, 0)
print(any(t2))

# one element is true others are false
t3 = (1, 0, False)
print(any(t3))

# one element is false others are true
t4 = (False, 1, 2, 3)
print(any(t4))

# empty tuple
t5 = ()
print(any(t5))

Output:
