Ive been searching around and can't to seem to find what the point of a "list" would be.

For example:

li = ['a', 'b', 'c']
li.extend(['d', 'e', 'f'])
print li [:6]
li.append ("new")
print li

Ok so this would create a list of a,b,c then extend the list to a,b,c,d,e,f then print the entire list of 'a', 'b', 'c', 'd', 'e', 'f'. After printing it would add the new item to the list in this case "new" and finally print out a final list including new to the end of the list.

Now i think i understand this but i don't understand what the point of doing this. What could it be used for? (Not just my example)

Logging?
Logs should be appended below each other, not overwritten.
I'm not sure what your point is though.

i was dead tired, but now i get it :D ty dsky

Not always just logging.. but yes DSKY is right it is used to append data so you are not overwriting a file and losing old data.

[hestas]

could you give some other examples Drath??

[Drathnar]

well lets say you are running a script on a database backbone like sql or oracle or something of the like... you would use a script such as that (not exactly but similar) in order to append records to the database vice overwriting the table each time the script is ran..


or in dealing with a file you could use it the same way lets say you have a mainframe that stores data.. you would then export the data and use that script to append the data to the file rather than overwriting the file.. so you have the data for historical purposes..

or you write a program that needs to keep track of things that were done in the past it would need to append rather than overwrite

So it is like logging but not logging in its default terminology rather historical data retention.

probably didn't help much lol but basically what i was trying to say is associating the word logging and solely logging with the process is not entirely correct as it is used for other things as well..

any time you would have the need to add rather than replace this would be a viable solution.
