1. "same data" versus "different files": are you using "different" in
the same sense as in "different machines" and "different results"? How
do you know the data is the same?

2. Either show us your script, or tell us (with a reasonable degree of
precision):
* how do you define a "word"
* what is a "word list"
* what is "a simple set operation on the word lists"
* does the script use any of: random module, current date/time,
iteration over dictionaries while updating them, etc

3. (a) Which of the two sets of results is correct? (b) What is your
basis for answering (a)?
