Another question with files

Question

I have dictionary in txt file with more than 350000 words, one word each line. I only need some of these words. Lets say ie. containing letters V, X, Q alone and with all of them. Should i use regex? How beat this problem?

Answer 1

Almost ;)

You must correct the writing of your 'if' statement... instead your:

if 'v' or 'x' or 'q' in word:

... correct syntax is:

if 'v' in word or 'x' in word or 'q' in word:
newDB.append(word)

( Obviously, you have to pass something to the method 'append()' :P )

Answer 2

Main idea was to have only correct words in this database and each time randomly get 50 words into list. But still dont know how get rid of not correct words. I think it should be something like this:

newDB = [ ]
if 'v' or 'x' or 'q' in word:
newDB.append()

Is it good idea?
