INNER JOIN gets all records that are common between both tables based on the supplied ON clause. LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.
The fact that when it says INNER JOIN, you can be sure of what it does and that it's supposed to be just that, whereas a plain JOIN will leave you, or someone else, wondering what the standard said about the implementation and was the INNER/OUTER/LEFT left out by accident or by purpose.
The result of join is always a string, but the object to be joined can be of many types (generators, list, tuples, etc). .join is faster because it allocates memory only once. Better than classical concatenation (see, extended explanation). Once you learn it, it's very comfortable and you can do tricks like this to add parentheses.

You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope.
Ah, but new experts will rise up and embrace the new, friendly Stack Overflow that they have always wanted. And maybe rediscover the same things the bitter, hateful old guard found.
New does not guarantee heap allocation and simply avoiding new does not guarantee stack allocation. New is always used to allocate dynamic memory, which then has to be freed. By doing the first option, that memory will be automagically freed when scope is lost.
It is NOT 'bad' to use the new keyword. But if you forget it, you will be calling the object constructor as a regular function. If your constructor doesn't check its execution context then it won't notice that 'this' points to different object (ordinarily the global object) instead of the new instance. Therefore your constructor will be adding properties and methods to the global object ...

When reading, list is a reference to the original list, and list[:] shallow-copies the list. When assigning, list (re)binds the name and list[:] slice-assigns, replacing what was previously in the list. Also, don't use list as a name since it shadows the built-in.
The second, list(), is using the actual list type constructor to create a new list which has contents equal to the first list. (I didn't use it in the first example because you were overwriting that name in your code - which is a good example of why you don't want to do that!)

By using a : colon in the list index, you are asking for a slice, which is always another list. In Python you can assign values to both an individual item in a list, and to a slice of the list.
