Exclude words with specific endings from list - Epileptiker - Apr-05-2018

Hey, is there a way to exclude words from a list that have specific endings, like every single word that ends with -s or -en? In my script i import some lists from external files to my script and these lists are very long and i can't delete the specific words by myself, because it would take days. So i thought there may be a python-command or something. This is my script:

import random, time, tweepy, ast
 
with open('liste1.txt') as infile:
    list1 = ast.literal_eval(infile.read())

with open('liste1.txt') as infile:
    list1 = ast.literal_eval(infile.read())

with open('liste1.txt') as infile:
    list1 = ast.literal_eval(infile.read())
 
def one():
    return random.choice(list1) + random.choice(list2)
 
def two():
    return random.choice(list2) + random.choice(list3)
 
#I'm working on a Twitter bot, that's just some twitter stuff down here 
consumer_key = 'XXX'
consumer_secret = 'XXX'
access_token = 'XXX'
access_token_secret = 'XXX'
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)
 
while True:
    postthis = random.choice([one,two])()
    if len(postthis) <= 140:
        api.update_status(status=postthis)
        time.sleep(10)

Thanks :)

First, why are you reading the file three times? That's just unnecessary.

But sure, you can totally do that. Something as simple as:

list1 = [item for item in list1 if not item.endswith("-s") and not item.endswith("-en")]

Okay i just tried it by copying this code in my script right here, but when i run it, it still posts words with these two endings. No error message. What have i done wrong? ...

with open('list2.txt') as infile:
    list2 = ast.literal_eval(infile.read())
    list2 = [item for item in list2 if not item.endswith("-s") and not item.endswith("-en")]

Do you have some example input/output?

RE: Exclude words with specific endings from list - Epileptiker - Apr-06-2018

I replaced the content of my list #2 with the items ["aaa", "bbb", "ccc"] and excluded every word that ends with -b and -c. When i run the module, it still posts and alternates between all three items.

This is the whole script right now.

import random, time, tweepy, ast

with open('list1.txt') as infile:
    list1 = ast.literal_eval(infile.read())

with open('list2.txt') as infile:
    list2 = ast.literal_eval(infile.read())
    list2 = [item for item in list2 if not item.endswith("-b") and not item.endswith("-c")]

with open('list3.txt') as infile:
    list3 = ast.literal_eval(infile.read())

def one():
    return random.choice(list1) + random.choice(list2)

def two():
    return random.choice(list2) + random.choice(list3)

consumer_key = 'XXX'
consumer_secret = 'XXX'
access_token = 'XXX'
access_token_secret = 'XXX'
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)

while True:
    postthis = random.choice([one])()
    if len(postthis) <= 140:
        api.update_status(status=postthis)
        time.sleep(10)
