any keyword evaluates to True if any one item in the supplied list is True or 1.
any is like applying an or statement over a list of items

x = True
y = False
z = False

k = any([x,y,z])
print(k) # True

k = any([False, False, False])
print(k) # False

k = any([0,0,1])
print(k) # True

k = any([0<5, 20>50, 40*2==80])
print(k) # True

all keyword evaluates to True only if all items in the supplied list is True or 1.
all is like applying an and statement over a list of items

x = True
y = False
z = False

k = all([x,y,z]) 
print(k) # False

k = all([True, True, True]) 
print(k) # True

k = all([0,0,1])
print(k) # False

k = all([0<5, 20>50, 40*2==80])
print(k) # False

Practical Example

nums = [5,21,54,96,71]

# check if any one number is less than 10
k = [x<10 for x in nums]
print(k) # [True,False,False,False,False]
isAnyLt10 = any(k)
if isAnyLt10:
	print("Atleast one number is less than 10 in the list")

# check if all numbers are greater than 50
k = [x>50 for x in nums]
print(k) # [False, False, True, True, True]
isAllGt50 = all(k)
if not isAllGt50:
	print("All numbers are not greater than 50 in the list")
