I'm working on a project that searches for filenames that match a string. The current working code appends an * to the end of the string and the code properly takes the string and matches it when there's a file extension and/or a number after, that works right. I'm wanting it to ignore things before the initial string as well to check the interior of the file name. For example File A File B.txt will be found by a string search for File A "or File B
Working code:
redeemed = redeemed + "*"
results = [file for file in sounds if re.search(redeemed, file)]
Non-working code:
redeemed = "*" + redeemed + "*"
results = [file for file in sounds if re.search(redeemed, file)]
Returns error:

We were concerned the code with redeemed would catch EVERYTHING, but instead it catches nothing. Any ideas on how to implement this search?
If it's just a plain text search, you don't need regex or glob:
results = [file for file in sounds if redeemed in file]
No * or .* needed
