Any and all function

• They’re nice for testing stuff
• you can just loop over the iterable and check manually

all

• Takes an iterable as an argument
• returns True is all elements of the iterable are truthy (or if the iterable is empty)

all([0,1,2,3]) # False
 
# You can check if the items in an iterable meets a certain condition
# checking if all names start with "C"
people = ["Charlie", "Chuck", "Cody"]
all([name[0].upper="C" for name in people]) 
# list is [True,True,True], so all returns True
 
#checking is all nums are even
nums = [2,3,6]
all([num % 2 == 0 for num in nums]) # False
all(num % 2 == 0 for num in nums) # False (don't need [], it's a generator)
 
# checking if all iterms are string
def is_all_strings(iterable):
    return all(type(item)==str for item in iterable)

any

• returns True if any element of the iterable is truthy
• returns False if the iterable is empty

any([0,1,2,3]) # True
