I would expect not. But I never know what someone else is going to do.

But in my case there is a Twitter directory with:
quotes.txt
quotes.pickle
tips.txt
tips.pickle
All four files are normally only accessed by the Python program. When
I want to extend the messages I use a text editor to append them.
The .txt files contain messages that can be used. And the .pickle
files contain the ‘recently’ used messages.
When I unpickle quotes.pickle I get:
[25, 112, 4, 18, 41, 2, 81, 75, 28, 60, 105, 47, 84, 65, 103, 42,
13, 66, 55, 124, 6, 82, 76, 12, 61, 113, 119, 96, 3, 68, 11, 89,
98, 107, 118, 29, 57, 33, 88, 121, 110, 49, 90, 72, 87, 114, 43,
59, 8, 92]
Very simple indeed.
