Answer 1

A for loop in Python works on a container type:

A list, dict, set, range, string or really anything else with multiple elements that can be iterated over.

Let me give a few examples with pseudo code that may give you some intuition of how to read it:

for book in bookshelf:
read(book)

(This means: Take every book from the bookshelf one by one and read them.)

for task in textbook:
do(task)

for word in vocabulary:
repeat(word)

but the read do what on the code ? I understand the print who print all the book but the read ? ...

Thanks for your help HonFu !
