Python any() vs all() functions
Learn the difference between any() and all() built-in functions in Python.

In this article, you will learn about the any()
and all()
built-in functions in Python. These built-in functions perform the AND and OR operation respectively.
Let’s understand how the AND and OR operators work in Python.
Topics Covered
and operator in Python
The "and" operator returns True if all the conditions are True.
Code/Output
print((2==2) and ("Pylenin" == "Pylenin"))
>>> True
print((2==2) and ("Pylenin" == "Python"))
>>> False
In the second print statement, since Pylenin
and Python
are not the same, the and
operator returns False.
You can also compare booleans.
Code/Output
print(True and True)
>>> True
print(True and False)
>>> False
print(False and False)
>>> False
It is also possible to chain multiple "and"s in a single statement.
Code/Output
print(True and True and True)
>>> True
print(True and False and True and True)
>>> False
or operator in Python
The "or" operator returns True if any of the conditions are True.
Code/Output
print((2==2) or ("Pylenin" == "Pylenin"))
>>> True
print((2==2) or ("Pylenin" == "Python"))
>>> True
In the second print statement, even though Pylenin
and Python
are not the same, the "or" operator returns True as the previous comparison holds True.
You can also compare booleans.
Code/Output
print(True or True)
>>> True
print(True or False)
>>> True
print(False or False)
>>> False
It is also possible to chain multiple "or"s in a single statement.
Code/Output
print(True or True or True)
>>> True
print(True or False or True or True)
>>> True
Python all()
The all(iterable)
built-in function takes in an iterable and returns True if all the elements of the iterable evaluate to True.
It is similar to the and
operator.
Code/Output
print(all([True, True, True]))
>>> True
print(all([True, True, False]))
>>> False
print(all([1992==1992, type(1992) is int]))
>>> True
Check if multiple variables are of a single data type in Python
You can use all()
function along with isinstance() to check if multiple variables belong to the same type.
Code
x = "Pylenin"
y = 10
z = 3.5
# Check if all variables are integer
if not all(isinstance(i, int) for i in list((x, y, z))):
print("All variables are not integer")
else:
print("All variables are integer")
Output
All variables are not integer
Python any()
The any(iterable)
built-in function takes in an iterable and returns True if any of the elements of the iterable evaluate to True.
It is similar to the or
operator.
Code/Output
print(any([True, True, True]))
>>> True
print(any([True, True, False]))
>>> True
print(any([1992==1992, type(1992) is str]))
>>> True
Check if any variables are of a particular data type in Python
You can use any()
function along with isinstance() to check if any variables belong to a particular data type.
Code
x = "Pylenin"
y = 10
z = 3.5
# Check if any variable is integer
if not any(isinstance(i, int) for i in list((x, y, z))):
print("There are no integers")
else:
print("There are integers")
Output
There are integers
Note - Use any()
and all()
only when they make the code shorter and maintain readability.
