Question

I’ve got some code that looks like this:

    valid = set()
    for string in substrings:
       for line in dictionary_words:
           if string in line:
               valid.add(string)
    f.writelines(sorted(valid))

Both dictionary_words and substrings are currently lists.

After the substring is found inside any dictionary_words, it should just go ahead and move onto the next substring.

What is the best way of writing that?

Answer 1

valid = set()
for string in substrings:
  for line in dictionary_words:
      if string in line:
          valid.add(string)
          break
f.writelines(sorted(valid))

@F.C.: If you use continue instead of break, it will run the next iteration of the inner for-loop.
