Any All in Python

Last Updated : 01 Dec, 2023

Any and All are two built-in functions provided in Python used for successive And/Or. In this article, we will see about any and all in Python.

What is Any in Python

Any Returns true if any of the items is True and returns False if empty or all are false. Any can be thought of as a sequence of OR operations on the provided iterables. It short circuit the execution i.e. stop the execution as soon as the result is known.

Python any() Function Syntax

Syntax: any(list of iterables)

In the below example, we are showing any() function’s working and demonstration by using the below code.

Python3

# Since all are false, false is returned
print (any([False, False, False, False]))
 
# Here the method will short-circuit at the
# second item (True) and will return True.
print (any([False, True, False, False]))
 
# Here the method will short-circuit at the
# first (True) and will return True.
print (any([True, False, False, False]))

Output

False
True
True

In this another example, we are given two lists and we are seeing if any of the number in the list is divisible by 5 by using any function.

Python3

# This code explains how can we 
# use 'any' function on list 
list1 = []
list2 = []
 
# Index ranges from 1 to 10 to multiply
for i in range(1,11):
    list1.append(4*i) 
 
# Index to access the list2 is from 0 to 9
for i in range(0,10):
    list2.append(list1[i]%5==0)
 
print('See whether at least one number is divisible by 5 in list 1=>')
print(any(list2))

Output

See whether at least one number is divisible by 5 in list 1=>
True

What is Python all() function

All Returns true if all of the items are True (or if the iterable is empty). All can be thought of as a sequence of AND operations on the provided iterables. It also short circuit the execution i.e. stop the execution as soon as the result is known.

Python all() Function Syntax

Syntax: all(list of iterables)

In the below example, we are showing the demonstration and working of the all() function with the help of code below.

Python3

# Here all the iterables are True so all
# will return True and the same will be printed
print (all([True, True, True, True]))
 
# Here the method will short-circuit at the 
# first item (False) and will return False.
print (all([False, True, True, False]))
 
# This statement will return False, as no
# True is found in the iterables
print (all([False, False, False]))

Output

True
False
False

In this another example, we are seeing of all numbers in list1 are odd and by using all() function, if they are odd then we will return True otherwise False.

Python3

# Illustration of 'all' function in python 3
# Take two lists 
list1=[]
list2=[]
 
# All numbers in list1 are in form: 4*i-3
for i in range(1,21):
    list1.append(4*i-3)
 
# list2 stores info of odd numbers in list1
for i in range(0,20):
    list2.append(list1[i]%2==1)
 
print('See whether all numbers in list1 are odd =>')
print(all(list2))

Output

See whether all numbers in list1 are odd =>
True
