Any and All

Python provides two functions that deal with iterable and return True or False depending on which boolean values elements of the sequence evaluate to.

• All

all(iterable) returns True if all elements of an iterable are considered as true values

e.g.,

all(l == 'y' for l in 'Python') # Returns False. Not all of the letters are 'y'.

• Any

any(iterable) returns True if at least one element of the iterable is a true value

e.g.,

any(l == 't' for l in 'python') # Returns True. Same as: 't' in 'python'
