Python any()

The syntax of any() is:

any(iterable)

any() Parameters

The any() method takes an iterable (list, string, dictionary etc.) in Python.

Return Value from any()

any() returns:

• True if at least one element of an iterable is true
• False if all elements are false or if an iterable is empty

Example 1: How any() works with Python List?

l = [1, 3, 4, 0]
print(any(l))

l = [0, False]
print(any(l))

l = [0, False, 5]
print(any(l))

l = []
print(any(l))

When you run the program, the output will be:

True
False
True
False

The any() method works in similar way for tuples and sets like lists.

Example 2: How any() works with Python Strings?

s = "This is good"
print(any(s))

# 0 is False
# '0' is True
s = '000'
print(any(s))

s = ''
print(any(s))

When you run the program, the output will be:

True
True
False

Example 3: How any() works with Python Dictionaries?

In case of dictionaries, if all keys (not values) are false, any() returns False. If at least one key is true, any() returns True.

d = {0: 'False'}
print(any(d))

d = {0: 'False', 1: 'True'}
print(any(d))

d = {0: 'False', False: 0}
print(any(d))

d = {}
print(any(d))

# 0 is False
# '0' is True
d = {'0': 'False'}
print(any(d))

When you run the program, the output will be:

False
True
False
False
True
