When looping over a list, a for loop executes code as many times as there are items in the list.
"color" is just a variable (you can name it anything) that points to each item in the list corresponding to what repetition it's on -- that's the cool thing. Example:
refrigerator = ['broccoli', 'kale', 'cabbage', 'spinach', 'avocado', 'onion']
for healthy_veg in refrigerator:
print(healthy_veg)
This will output:
broccoli
kale
cabbage
spinach
avocado
onion
This loop will iterate 6 times because there are 6 items in the list.
first iteration: the variable healthy_veg points to 'broccoli'
second iteration: healthy_veg points to 'kale'
third iteration: healthy_veg points to 'cabbage'
fourth iteration: healthy_veg points to 'spinach'
fifth iteration: healthy_veg points to 'avocado'
sixth iteration: healthy_veg points to 'onion'
A while ago, I also had trouble understanding this. I hope I made it clear for you, now.
If you need any more help, just say the word!
