short_str in long_str

[nilamo]

If I add 'book' in the first variable and 'notebook' in the second it will give True although book and notebook are different things. The reason is that last 4 characters in 'notebook' match with 'book'.

In order to get around that, you should split the string into a list of available options. The in operator can still be used at that point.

>>> can_read = "book"
>>> things = "website, blog, book"
>>> can_read_things = things.split(", ")
>>> can_read_things
['website', 'blog', 'book']
>>> can_read in can_read_things
True
>>> things = "website, blog, notebook"
>>> can_read_things = things.split(", ")
>>> can_read in can_read_things
False
