Just a question about what can used in the for loop. From the lesson,
The general way of writing a for loop is:
for <temporary variable> in <list variable>:
<action>
Is “list” saying that the variable has to be a list type or is it casting the variable to a list? Couldn’t you use any thing you could iterate on like a range(x)?
the specification of what you iterate through is an expression, it does not need to be a list it does not need to be a variable it does need to be iterable
the variable is not temporary, it exists after the loop as well. it’s a variable, nothing special
“Why can’t we assign more than one word to the temporary variable?”
Remember a variable is like a box, the specific collection of symbols/characters is the label that tells us what’s in the box.
Each collection of symbols has a specific definition/purpose. By using a space you’re using two separate collections (aka words) that then require two separate definitions. Remember computers don’t speak english, they don’t know what a word (variable) means they just know that this collection of symbols refers to this other collection of symbols.
Programming best practices suggest we make our temporary variables as descriptive as possible. Since each iteration (step) of our loop is accessing an ingredient it makes more sense to call our temporary variable ingredient rather than i or item.

oh and is this statement true? ‘i’ or ‘item’ is perfectly fine
