numbers = [1,2,3,4,5,6,7,8,9,10]
for num in numbers:
    print(num)
    
# length of list
print(len(numbers))

# retrieving values with index values
print(cities[0])


print(cities[1])
print(cities[2])

# Finding EVEN and ODD in list
numbers = [1,2,3,4,5,6,7,8,9,10]
for num in numbers:
    if num%2 == 0:
        print(str(num)+": EVEN")
    else:
        print(str(num)+": ODD")
        
# sum all values in list
numbers = [1,2,3,4,5,6]
print(sum(numbers))
