在循环中连续调用函数并输出不同的结果

Question

I am creating a small program that pulls quotes of a certain artist and then posts a random line from a random song of theirs onto Twitter. I have so far managed to pull the lyrics, get a random line from a random song but it always posts the same lyric. I understand why this is happening as it isn't only looping through the same output earlier on. Could you advise how I can get the loop to pull a new song and then a new random lyric each time it loops round? I have tried to call the 'lyricsimport' function within the loop to no avail

I'm quite new to Python please feedback any improvements if necessary - thank you in advance

Here is my code so far...

# Import Twitter credentials from credentials.py
import random
from tswift import Artist
import tweepy
from time import sleep
from credentials import *

# Access and authorize our Twitter credentials from credentials.py
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)

#get lyrics from tswift and save to text file
def lyricsimport():
    tswift = Artist('Frank Ocean')
    song = random.choice(tswift.songs)
    savefile = open('ocean.txt', 'w')
    savefile.write(song.format())
    savefile.close()


# Open text file ocean.txt (or your chosen file) for reading and select random lyric
with open('ocean.txt') as f:
    my_file = f.readlines()
    file_lines = random.choice(my_file)

# Tweet a line every 10 seconds (will change post-testing)
def tweet():
    # Create a for loop to iterate over file_lines
    for line in file_lines:
        try:
            print(file_lines)
            #if statement to ensure that blank lines are skipped
            if line != '\n':
                api.update_status(file_lines)
                sleep(10)
            else:
                pass
        except tweepy.TweepError as e:
            print(e.reason)
            sleep(2)
tweet()

Answer 1

my_file is all the lines in the file, right? and so file_lines is a random.choice from those, and random.choice only returns a single value... This should be visible by print(file_lines) - should be just a single line.

How about you replace

    api.update_status(file_lines)

in your loop with

    api.update_status(random.choice(my_file))

?

The file opening should look like this:

with open('ocean.txt') as f:
    my_file = f.readlines()

And let's see if that helps :)
