Yes, this solution would solve the current problem. But theoretically the
uniqueness may be defined by the directory, where the file is located, not
by the name. It looks very unlikely, but who knows...
I thought about what Stella have said, and it seems that I have found a
good solution for this. We can use something like `tempfile` (
https://docs.python.org/3.7/library/tempfile.html) for every internally
generated file of the script. It will guarantee us the uniqueness of the
file. But for the uniqueness of files named by script parameters the script
user will remain responsible.
What do you think about the such approach?
