我将如何 select 文件中的随机单词供用户解读？

Question

I am trying to select a random word from a txt file. The context of the file has been provided. I would like the word to be random every time the code is ran. I also only need the words before the comma

import random 
print("Please enter mywords file to start game")

user_input=input('Enter file name')
filename = open(user_input)
info=filename.readlines()
filename.close()

words=info[0-3]
objects=words.split(',')
userword=random.choice(objects)
print(userword)

opulence,great wealth
penury,extremely poor
gregarious,fond of company; sociable
entomology,study of insects

So far I able to pull from the second line in the file "penury,extremely poor"

Answer 1

You were trying to slice, but end up with just one line. You can do a loop over the lines, split on ',' and form a list with what's required. Later, randomly pick from the list:

lst = []

for x in info:
    w, _ = x.split(',')
    lst.append(w)

print(random.choice(lst))

Answer 2

0-3 seems to be a typo of 0:3 , but the problem goes deeper than that. words is supposed to be a list, and lists don't have a .split method. You'll need to split each item (and select the part before the comma).

words = [line.split(',')[0] for line in info]
userword = random.choice(words)
