运行程序时出错

Question

try:
    import sys
    # For Python 3.0 and later
    from urllib.request import urlopen
except ImportError:
    # Fall back to Python 2's urllib2
    import sys
    from urllib2 import urlopen

def fetch_words(url):
    html = urlopen(url)
    print(html.read())
    story_words = []
    for line in html:
        line_words = line.decode('utf-8').split()
    for word in line_words:
        story_words.append(word)
    return story_words


def print_items(items):
    for item in items:
        print(item)


def main():
    url = sys.argv[1]
    words = fetch_words(url)
    print_items(words)

if name == '__main__'
    main()

Answer 1

您可能还有其他错误，但肯定没有声明name，所以

if name == 'main'

会给你一个错误。相反，它应该是

if __name__ == '__main__'
