compare two lists of files, ignoring file extension in one list

Question

I have two lists

list1 = [\'image1.png\', \'image2.png\', \'image3.png\', \'image3.png\']
list2 = [\'image1.pdf\', \'image2.eps\', \'image3.ps\']
         


        

Answer 1

def filename(name):
    return name.split('.')[0]

list2_filenames = [filename(name) for name in list2]
found_filenames = [name for name in list1 if filename(name) in list2_filenames]
