Any function in Python – any() With Example

In this tutorial, we are going to learn about any function in python – any() function with example.

Getting Started

any() function in python returns True if any element in iterable is true. Otherwise, it returns False.

If iterable object is empty, it returns False.

Now, we will learn about syntax of any() function in python.

Syntax of any() Function

Below line represents syntax of any() function –

any(iterable)

Where,
iterable is an iterable object argument that can be list, tuple or dictionary etc.

For example,

any([1,2,3])

Here,
We have passed list as arguments to any() function that have elements 1, 2 and 3.

Parameters of any() Function

As discussed above, any() function accepts one iterable as arguments. It can be list, tuple or dictionary etc.

Return Type of any() Function

any() function returns boolean value True or False

  1. True: If at-least one item is iterable is True.
  2. False: If all items in iterable are False.
Condition Return Values
Values of All Items are True True
Values of All Items are False False
Value of any one item is True (Others are False) True
There is no item in Iterable. False

Examples of Python any() Function

Now, we will see how to use any() function with –

  1. List
  2. Tuple
  3. Set
  4. String
  5. Dictionary
  1. Using Python any() Function with List

    any() function in python can be used with Python List as shown below –

    # True because all items in list are True (i.e. non zero values)
    list1 = [11, 21, 20, 19]
    print(any(list1))
    

    Output:

    True
    

    list1 has elements 11, 21, 20 and 19. It means all items in list1 are non-zero values which are considered True. Hence, any(list1) will return True.

    Let’s see some other conditions of any() function with List –

    • Values of All Items are True

      When all items are true in list, any() function will return true.

      For example,

      # True: All items in list are True (i.e. non zero values)
      list1 = [100, 211, 210, 119]
      print(any(list1))
      

      Output:

      True
      
    • Values of All Items are False

      For example,

      # False: All items (0 and False) in list are False
      list2 = [0, False]
      print(any(list2))
      

      Output:

      False
      

      0 is considered false. So, all items in list are false. Hence, any() will return False.

    • Value of any one item is True

      For example,

      # True because at-least one item is True
      list3 = [0, False, 9]
      print(any(list3))
      

      Output:

      True
      

      9 is non-zero value i.e. True. So, any() returns True.

    • There is no item in List

      For example,

      # False because list is empty
      list4 = []
      print(any(list4))
      

      Output:

      False
      
  2. Using Python any() Function with Tuple

    We can use any() method with tuple in similar ways as List.

    For example,

    tuple1 = (1, 21, 20, 89)
    print(any(tuple1))
    

    Output:

    True
    

    Let’s see some other conditions of any() function with Tuple –

    • Values of All Items are True

      For example,

      # True because all items in tuple are True (i.e. non zero values)
      tuple1 = (32, 54, 60, 99)
      print(any(tuple1))
      

      Output:

      True
      
    • Values of All Items are False

      For example,

      # False because both (0 and False) are False
      tuple2 = (0, False)
      print(any(tuple2))
      

      Output:

      False
      
    • Value of any one item is True

      For example,

      # True because at-least one item is True
      tuple3 = (0, False, 9)
      print(any(tuple3))
      

      Output:

      True
      
    • There is no item in Tuple

      For example,

      # False because tuple is empty
      tuple4 = ()
      print(any(tuple4))
      

      Output:

      False
      
  3. Using Python any() Function with Set

    We can use any() method with Python Set in similar ways as List.

    For example,

    set = {32, 54, 60, 99}
    print(any(set))
    

    Output:

    True
    

    All items in Set are True. So, any() function will return True.

    Enlighten yourself on Python Set –

    2. How to Create an Ordered Set in Python ?

    Let’s see some other conditions of any() function with Set –

    • Values of All Items are True

      For example,

      # True because all items in Set are True (i.e. non zero values)
      set1 = {32, 54, 60, 99}
      print(any(set1))
      

      Output:

      True
      
    • Values of All Items are False

      For example,

      # False because both (0 and False) are False
      set2 = {0, False}
      print(any(set2))
      

      Output:

      False
      
    • Value of any one item is True

      For example,

      # True because at-least one item in Set is True
      set3 = {0, False, 9}
      print(any(set3))
      

      Output:

      True
      
    • There is no item in Set.

      For example,

      # False because Set is empty
      set4 = {}
      print(any(set4))
      

      Output:

      False
      
  4. Using Python any() Function with String

    any() function in python also works with String. It checks if all characters in string are true or false. Based on this condition, it returns either True or False.

    For example,

    str1 = "Hello Tutorialwing!"
    print(any(str1))
    

    Output:

    True
    

    Enlighten yourself on Python String –

    1. Python Program to Print String (With Example)
    2. Python Program to Read String as Input (With Example)

    Let’s see some other conditions of any() function with String –

    • At-least one of all characters in String are True

      If one or many characters in string are True, any() function returns True.

      For example,

      str1 = "Welcome to Tutorialwing!"
      print(any(str1))
      

      Output:

      True
      
    • All characters in String are 0

      0 is considered false. But, ‘0’ is True because it is a character. So, any() function will return True.

      For example,

      # 0 is False. But, '0' is True because it's string character.
      str2 = '000000'
      print(any(str2))
      

      Output:

      True
      
    • There is no Character in String

      For example,

      # String is empty. So, it's False
      s = ''
      print(any(s))
      

      Output:

      False
      
  5. Using Python any() with Dictionary

    any() function in python can also be used with dictionary like we use it with list or tuple.
    In case or dictionary, it checks if keys are True or False. Based on this condition, it returns true or false.

    For example, if at-least one key is True, any() function returns True. Otherwise, it returns False.

    For example,

    dict = {'name': 'Tutorialwing'}
    print(any(dict))
    

    Output:

    True
    

    Here, Dictionary has only one key – ‘name’ which is True. So, any() function will return True.

    Let’s see some other conditions of any() function with Dictionary –

    • All keys of Dictionary are True

      For example,

      dict3 = {10: 'False', 12: 0}
      print(any(dict3))
      

      Output:

      True
      
    • All keys of Dictionary are False

      For example,

      dict1 = {0: 'False', False: 'Hello'}
      print(any(dict1))
      

      Output:

      False
      
    • At least one key of Dictionary is True

      For example,

      dict2 = {0: 'False', 45: 'True'}
      print(any(dict2))
      

      Output:

      True
      
    • Dictionary is Empty

      For example,

      dict4 = {}
      print(any(dict4))
      

      Output:

      False
