Moreover, you could do it all in one step ('w+' stands for “clear file

I'm always very wary of recommending mixed read/write mode to beginners.
Its simple in this case but in other scenarios its very easy to lose
track of where the cursor is and start overwriting your previously
written data!
I usually recommend writing the data, closing the file, and then opening
for reading.
Powerful tools have the capacity to be powerfully bad as well
as good...
