Any All in Python

  • Difficulty Level : Easy
  • Last Updated : 25 Nov, 2020

Any and All are two built ins provided in python used for successive And/Or.

Any
Returns true if any of the items is True. It 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.

Syntax : any(list of iterables)






# 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

 

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.

Syntax : all(list of iterables)




# 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

Practical Examples




# 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




# Illustration of 'all' function in python 3
  
# Take two lists 
list1=[]
list2=[]
  
# All numbers in list1 are in form: 4*i-3
for 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
