The built-in function "all()" in python
The Python built-in function "all()" returns True if all elements in an iterable are true, and False otherwise. The iterable can be a list, tuple, dictionary, set, or any other object that can be iterated over. The general syntax for using the all() function is:
all(iterable)
where iterable is the object that needs to be checked for truthiness.

Example

>>> all([True, True, True])
True
>>> all([True, False, True])
False
>>> all([1, 3, 4, 5])  # All numbers are considered True in Python
True
If the iterable is empty, the function returns True.

Example

>>> all([])
True
You can also use the all() function with a generator expression or a list comprehension.

Example

>>> all(i > 5 for i in [6, 7, 8])
True
>>> all(i > 5 for i in [6, 7, 3])
False
