You can write anything to a file, but the file will need to
be opened in binary mode(see the docs). The tricky bit
is reading the data back, you will need to find a way
to convert the bytes read from the file into whatever
the original data structure was.

For that reason it is usually better to use a tool like
pickle or shelve to store Python objects in a file
(again see the docs)
