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

Use a list comprehension with set:

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

print [x for x in set(list1) for y in set(list2) if x.split('.')[0] == y.split('.')[0]]

Output:

['image1.png', 'image2.png', 'image3.png']
