I'm trying to create a program that lets the user type in anything they want and that stores everything that has ever been typed into it (i.e. it doesn't disappear when the program closes). I've tried looking online for tutorials on how to work with files in python but those tutorials never seem to mention how to create a file. Anyone know how?

You mean basic file io with python? Like this?

Yes, but I need to know that my files will continue to exist and store the data after I close the program.

In the same directory as your program, a file will appear called "name.txt" if you execute this code in your program:

file = open("name.txt", "w")

Continue to write "lines" in your program to the text document with:

file.write(line)

When you have finished use:

file.close()

The file will continue to exist and store the data in the same directory you ran your Python program from.

That's not working for me.
No matter how many times I run the following code

filename = "name.txt"
FILE=open("name.txt", 'w')
FILE.write("Hello World ")
FILE.write("Hello World")
FILE.close()
FILE=open("name.txt",'r')
print FILE.readlines()
FILE.close()

It always outputs "Hello World Hello World"

That's what you wrote to the file though, so that's what it's going to say. What did you expect/want it to say?

The second time I run the program, I need it to print "Hello World Hello World" twice and on the third time I need it to print "Hello World Hello World" three times. What do I need to do to get it to save the info I store in it?

[Simown]

In that case you need to open the file in "append" mode to add to the end of the file:

file = open("name.txt", "a")

And then just write items and close as usual.

Thanks

Will append work if you haven't added anything in the file yet?
