# Python List
fruits = ["tao", "chuoi", "cam", "mit", "dua hau", "kiwi", "ca chua"]

# Access item in list, access first item by index, start from 0

# loop through a list
# for fruit in fruits:
#     print(fruit)

# check if item in list
"chuoi" in fruits
"chuoi " in fruits

# List length
len(fruits)

# Add items to end
