os.path and manipulating the records within the list

[cemixa]

I have around 100 ASCII files in a folder. I will apply some processing on each ASCII file and save them as raster files.
In order to work with each ASCII file I have created the following access:
workspace = "C:\\ASCII\\1950"
foldername = join(workspace,'*.asc')
AsciiFiles = glob.glob(foldername)

The result is a list like :
[‘'C: \\1950-1.asc', 'C: \\1950-2.asc', 'C\1950-3.asc']
I would like to create a new list which will include the path and file name of the outputs, and that list should look like this
[‘'C: \\1950-1.tiff, 'C: \\1950-2.tiff', 'C\\1950-3.tiff']
Thank you for your help.

Look at string.replace and replace ".asc" with ".tiff".

This is not the only way, but I had a similiar situation and this is how I solved it. It iterates through the list of files, chops the last three digits off, and adds 'tiff'. Then it adds that to a new list.

asclist = ['C: \\1950-1.asc', 'C: \\1950-2.asc', 'C\\1950-3.asc']
tifflist=[]
for asc_file in asclist:
    tifflist.append(asc_file[:-3]+'tiff')

I always use the dot, ".asc", [:-4], in my paranoid world when replacing, globbing, etc. because it eliminates files that end with just asc.
