AND operation for Boolean array's elements

I have a variable length Boolean array as shown below:

ARR = [True, False, True, False,...]

Is there any simplest way (single line) to perform AND operation for all elements, as below?

ARR[0] and ARR[1] and ARR[2] and ARR[3] and ARR[*]...

Solution 1:

There is a builtin, called all, which will and together all its arguments. For example:

>>> ARR = [True, False, True, False,]
>>> all(ARR)
False

And:

>>> ARR2 = [True, True, True,]
>>> all(ARR2)
True

The argument to all need not be a list of booleans. Anything can be used as long as python can evaluate it to true or false. For example:

>>> all([True, 10, 'name'])
True
>>> all([True, 0, 'name'])
False

Since you want the and operation done, it should return True if all the elements in the list are True. So this simple line will do:

print(False not in bool_list)

This line looks for a False in the given list, thus technically doing the and operation
