me and Bob are in tune, it seems, I was composing the same message. Would like to add that in python 3.x the 'b' does make a difference, since read and write will use the 'bytes' type. Also, if you don't mind a binary file, I would also like to suggest the following non-python solution: $ dd if=/dev/urandom of=rand_numbers.txt count=100MB and adjust the count argument to your liking.
