Any and All in Python

Any() and All() function in Python 

Python provides two inbuilt functions for "AND" and "OR" 'operations as "All" and "Any" functions.

Any() function

The any() function returns true value if any of the item is true otherwise it will return false if empty or all items are false.

It stops the iteration or we can say it short circuit the execution if the result is known.

Syntax: any (list of iterables) 

check all item in tuple

my_list=[False,False,False,False]

mylst=[False,True,False,True]

x=any(my_list)

y=any(mylst)

print(x)

print(y)

Output :

False
True

Lets see an another example related to this function()

check all item in list

print (any([False, False, False, False])) 

  

print (any([False, True, False, False])) 

  

 

print (any([True, False, False, False])) 

Output :

False
True
True

All() function

The all() function will returns True if all items in an iterable are true or if the iterable is empty,

It also short circuit the execution i.e. stop the execution further as soon as the result is known.

lets see an example with list, The iterable object can be list, tuple or dictionary.

mylst = [True, True, False]

my_list = [True,True,True]

x = all(mylst)

y = all(my_list)

print(x)

print(y)

Output :

False
True

lets see an another example

print (all([True, True, True, True])) 

  

print (all([False, True, True, False])) 

  

print (all([False, False, False])) 

Output :

True
False
False

An example with Dictionary

mydict = {0: "Apple", 1:"Banana"}

x = all(mydict)

print(x)

Output :

False

Now Lets see some practical examples

list1 = [] 

list2 = [] 

  

for i in range(1,11): 

    list1.append(4*i)  

  

for i in range(0,10): 

    list2.append(list1[i]%5==0) 

  

print("lets See whether at least the one number is divisible by 5 in the list 1=>") 

print(any(list2)) 

Output :

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