Closing the file you've read from is good, but not nearly as important 
as closing the file you've been writing to.

There's your problem ! You didn't close mynewfile before opening the 
file again for reading. Most likely, what you thought you've written to 
the file is still buffered in memory. The main purpose of closing a file 
after writing is to flush the contents of this buffer to disk.
Try mynewfile.close() just before infile = open ..

Best,
