any() and all() in Python
By Priya BhowmickToday we will discuss two functions in Python, ‘any’ and ‘all’ and their different examples. Python provides two built-in functions ‘any()’ and ‘all()’ to perform “AND” and “OR” operations.
Python any() function
Syntax: any(iterable)
It takes an iterable object as a parameter.
Return Value:
It can have two types of the return value:
- True: The
any()function returns True if at least one item in the iterable is true. - False: The
any()function returns False either if the iterable is empty or if none of the items in the iterable results as true.
It works similar to a sequence of ‘OR’ operations over the given iterable. It will stop the execution once we get the result.
Examples: any() function in Python
# any() function for a list
list1 = [ 0, False, 1, False]
x = any(list1)
print(x)
# any() function for a dictionary
dict1 = { 0 : "monday", 1: "tuesday"}
x = any(dict1)
print(x)
# any() function for a set
set1 = {False, False}
x = any(set1)
print(x)Output:
True True False
Python all() function
Syntax: any(iterable)
It takes an iterable object as a parameter.
Return Value:
It can have two types of the return value:
- True: The
all()function returns True either if the iterable is empty or if each and every item in the iterable is true. - False: The
all()function returns False even if a single item in the iterable is false.
It works similar to a sequence of ‘AND’ operations over the given iterable. It will stop the execution once we get the result.
Examples:
# any() function for a list
list1 = [ 0, False, 1, False]
x = any(list1)
print(x)
# any() function for a dictionary
dict1 = { 1 : "monday", 1: "tuesday"}
x = any(dict1)
print(x)
# any() function for a set
set1 = {True, True}
x = all(set1)
print(x)Output:
False True True
