Save as problem

[Kristenl2784]

>>> import os
>>> 
>>> input_dir = 'C:data' # There is a problem here
>>> output_dir = os.path.join(input_dir, 'output') 
>>> output_dir
'C:data\\output' 
>>> 
>>> # Fix
>>> input_dir = 'C:\\data'
>>> output_dir = os.path.join(input_dir, 'output') 
>>> output_dir
'C:\\data\\output'

I fixed the data part to input_dir = 'C:/data'

This still doesn't fix the issue I'm having when trying to do a save as. The script runs fine till the save part where I want to use the excel file "outputnames" which has a list of names I want to use. I don't want it to save with the same file name that initially get's read in. So I have a list in an excel file that has the names that I want each file to be saved as.
