hmm, thanks for the help. So I kinda got it working, although from an
efficiency perspective it leaves a lot to be desired.
I managed to do the following:
1) Create a script that gives me a list of all the filenames in the folder:
path = "...\\Leukemia_Project"
i = 0
for (files) in os.walk(path):
print(files)
print("\n")
i += 1
2) I manually copy and paste the resulting list from the IDLE interpreter
into a .txt file
3) Open the .txt file in Excel, remove the few lines I don't need (ie single
quotes, etc)
4) Write another python script to print the result from step 3 in a new txt
file, where each filename has its own row (pretty easy to do b/c all
separated by the tab in the original txt file)
5)Put a for loop around my original python script that takes as input each
line from the result of step 4.
As it stands it is painfully awkward, but it works and has already saved me
a lot of aggravation...
