为什么我的 function 在 REPL 中没有被识别

Question

For some reason when I run my program in the REPL my module isn't recognized. I type in from import words (fetch_words, print_words) and receive the error fetch_words is not defined . This happens as as well when I type import words

from urllib.request import urlopen

def fetch_words():
    story = urlopen('https://sixty-north.com/c/t.txt')
    story_words = []
    for line in story:
        line_words = line.decode('utf-8').split()
        for word in line_words:
            story_words.append(word)
    story.close()
    return story_words



def print_words(story_words):
    for word in story_words:
        print(word)


def main():
    words = fetch_words
    print_words(words)


if __name__ == '__main__':
    main() 

Answer 1

You have incorrect syntax while importing the function.

Since you have named your file as practice.py , the correct syntax of importing the function defined within it will be:

from practice import fetch_words

Or in case you need to import multiple functions:

from practice import fetch_words, print_words

Remember, the name of the module to import from should be the same as the name of the file, without .py extension. In this case, the module is practice , and not words .
