python - strip()方法如何与append()方法一起使用？

当我运行以下脚本时

WORD_URL = http://learncodethehardway.org/words.txt
WORDS = []
for word in urlopen(WORD_URL).readline():
    WORDS.append(word.strip())
print WORDS

python提供以下输出：

['a'，'c'，'c'，'o'，'u'，'n'，'t'，'']

我对strip（）方法和append（）方法如何工作感到困惑？还有readline（）在此脚本中的作用？

最佳答案

strip()方法采用您拥有的任何字符串，并删除结尾的空格和换行符

>>> '   asdfadsf '.strip()
'asdfadsf'

>>> '\nblablabla\n'.strip()
'blablabla'

>>> a = []
>>> a.append('   \n asdf \n    '.strip())
>>> a
['asdf']

>>> words = [' a ', '   b    ', '\nc\n']
>>> words = [word.strip() for word in words]
>>> words
['a', 'b', 'c']

更新问题的答案

from urllib import urlopen

WORD_URL = 'http://learncodethehardway.org/words.txt'
WORDS = []
word_list = urlopen(WORD_URL)
word_list = word_list.readlines()
print word_list                      # before strip()
for word in word_list:
    WORDS.append(word.strip())
print WORDS                          # after strip(), so you get an idea of what strip() does
