Remove lines that contain certain string

Question

I\'m trying to read a text from a text file, read lines, delete lines that contain specific string (in this case \'bad\' and \'naughty\'). The code I wrote goes like this:

Answer 1

to_skip = ("bad", "naughty")
out_handle = open("testout", "w")

with open("testin", "r") as handle:
    for line in handle:
        if set(line.split(" ")).intersection(to_skip):
            continue
        out_handle.write(line)
out_handle.close()
