Writing Files

Question

Is there any way to save the file's existing content, when the file is opened in write mode?

Answer 1

Later on, open it in the 'append' mode.

open(file_name, 'a')

Answer 2

You just close() it. Then it's saved.

Answer 3

If you don't want to overwrite the file, do NOT open it in write mode. You can use the "r+" mode or the "a" (append) mode instead.

Answer 4

when the file is opened in write mode again, file contents are removed. How to avoid this?
