all() is a Python built-in function to return True if all elements of the iterable argument are True or the iterable argument is empty.

#### Example 1 - all() with list of all True values

``````data_list = [True, True, True]
x = all(data_list)
print(x)``````
Output:

``````True
``````

#### Example 2 - all() with list of not all True values

``````data_list = [False, True, True]
x = all(data_list)
print(x)``````
Output:

``````False
``````

#### Example 3 - all() with list of all False values

``````data_list = [False, False, False]
x = all(data_list)
print(x)``````
Output:

``````False
``````

#### Example 4 - all() with an empty list

``````data_list = []
x = all(data_list)
print(x)``````
Output:

``````True
``````

#### Example 5 - all() with a set of all True values

``````data_set = {True, True, True}
x = all(data_set)
print(x)``````
Output:

``````True
``````

#### Example 6 - all() with a set of not all True values

``````data_set = {True, False, True}
x = all(data_set)
print(x)``````
Output:

``````False
``````

#### Example 7 - all() with a set of all False values

``````data_set = {False, False, False}
x = all(data_set)
print(x)``````
Output:

``````False
``````

#### Example 8 - all() with an empty set

``````data_set = {}
x = all(data_set)
print(x)``````
Output:

``````True
``````

#### Example 9 - all() with a tuple of all True values

``````data_tuple = (True, True, True)
x = all(data_tuple)
print(x)``````
Output:

``````True
``````

#### Example 10 - all() with a tuple of not all True values

``````data_tuple = (True, True, False)
x = all(data_tuple)
print(x)``````
Output:

``````False
``````

#### Example 11 - all() with a tuple of all False values

``````data_tuple = (False, False, False)
x = all(data_tuple)
print(x)``````
Output:

``````False
``````

#### Example 12 - all() with an empty tuple

``````data_tuple = ()
x = all(data_tuple)
print(x)``````
Output:

``````True
``````
