Question about files?

[corvettecraz92]

I want to create a program where a user can type what ever they want
to, have it saved to a file, and the be able to re-open it and read
it. How would I do this? Thanks!

import os
os.system("edit") * * # may be Windows specific

(or, to expand on it... Exactly what part of the task are you having
problems with? Opening files for read/write/update? Designing a command
set for an editor? Designing a GUI for a text editor; what toolkit, does
it have a generic text edit widget already? Do you really need to write
another text editor when there are so many available that come with most
operating systems (Windows: edit, notepad, maybe even wordpad;
UNIX/Linux type systems: vi, vim, gvim, emacs) or can be downloaded
(SciTE) )

No, what I mean is for the user to input text directly into the python
program, then the program would save it to a file and display it after
it is created.

No, what I mean is for the user to input text directly into the python
program

You can use raw_input() to ask user to type something, then use open()
to create a file and write in it.
http://docs.python.org/lib/bltin-file-objects.html

then the program would save it to a file and display it after
it is created.

What do you mean by "display"?
Open that file with a text editor? Print the content of the file on
screen?

Use a multi-line text-input widget (available on any widget library)

To open a file in python for reading:
filepointer = file('path/to/file', 'r')

then read it like this:
for line in filepointer:
dosomethingwith(f)

or:
filecontent = filepointer.read()

To open a file for writing:
filepointer = file('path/to/file', 'w')

to write to a file:
filepointer.write(somestring)
