The syntax of any() is:
any(iterable)
Parameters for the any() function
The any() function takes an iterable (list, string, dictionary etc.) in Python.
Value Returned by the any() function
The any() function returns a boolean value:
Trueif at least one element of an iterable is trueFalseif all elements are false or if an iterable is empty
| Condition | Return Value |
|---|---|
| All values are true | True |
| All values are false | False |
| One value is true (others are false) | True |
| One value is false (others are true) | True |
| Empty Iterable | False |
Example 1: Using any() on Python Lists
# True since 1,3 and 4 (at least one) is true
l = [1, 3, 4, 0]
print(any(l))
# False since both are False
l = [0, False]
print(any(l))
# True since 5 is true
l = [0, False, 5]
print(any(l))
# False since iterable is empty
l = []
print(any(l))
Output
True False True False
The any() method works in a similar way for tuples and sets like lists.
Example 2: Using any() on Python Strings
# Atleast one (in fact all) elements are True
s = "This is good"
print(any(s))
# 0 is False
# '0' is True since its a string character
s = '000'
print(any(s))
# False since empty iterable
s = ''
print(any(s))
Output
True True False
Example 3: Using any() with Python Dictionaries
In the case of dictionaries, if all keys (not values) are false or the dictionary is empty, any() returns False. If at least one key is true, any() returns True.
# 0 is False
d = {0: 'False'}
print(any(d))
# 1 is True
d = {0: 'False', 1: 'True'}
print(any(d))
# 0 and False are false
d = {0: 'False', False: 0}
print(any(d))
# iterable is empty
d = {}
print(any(d))
# 0 is False
# '0' is True
d = {'0': 'False'}
print(any(d))
Output
False True False False True
