# w Create an empty file for writing. If a file with the same name
# already exists its content is erased and the file is treated as a new
# empty file.

# file. The file is created if it does not exist.

# same name already exists its content is erased and the file is
# treated as a new empty file.

# a+ Open a file for reading and appending. All writing operations are
# performed at the end of the file, protecting the previous content
# from being overwritten.

# file for reading, but writing operations will move it back to the end of
