file in .exe not running properly but in visual studio code is working fine

i am looking for a solution on how i make my .exe python file works well just like in visual studio code. After converting the python file into .exe, it wont run well as it shows traceback error. Traceback Error ..
Reconvert again with –onefile -w in cmd

Code:

from time import sleep
from newspaper import Article, Config
    import nltk
from newspaper.article import ArticleException, ArticleDownloadState

def get_News():
    while True: 
        print ("Enter URL: ")
        url = input('')
        print("n")
        user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0'

        config = Config()
        config.browser_user_agent = user_agent
        config.request_timeout = 10

        article = Article(url, config=config, lang='en')
        slept = 0
        article.download()
        article.parse()    

        title = article.title
        author = article.authors
        pub_date = article.publish_date
        text = article.text 

        article.nlp()

        print('Display Title, Author and Publish Date:')
        print(title ,author, pub_date)
        print ('n' +'Display Text from Article: ' + 'n' + text)
        print ('n' + 'Display Article Summary: ')
        print(article.summary)
        print('n')
        print('Display Keywords: ')
        print(article.keywords)

        if url == '':
            print('No URL Found. Exiting the Program...')
            break
        if __name__ == '__main__': 
        get_News()

I am using Visual Studio Code and to convert into .exe, i use py -m PyInstaller –onefile -.py

Thanks for your help and solutions !
