Question

我试图阅读一个句子，并且对于句子中的每个单词，检查单词是否存在某些撇号，并且如果它们存在，则替换它们继续。我在dict中定义了我的撇号。 dict的key具有模式，value具有替换模式的实际值。我尝试了以下代码

tweet = "you're his i'm couldn't can't won't it's"
apostrophes = {"'s":" is","'re":" are","'ll":" will","'d":" would","i'm":"I am","I'm":"I am","won't":"will not", "'ve":" have","can't":"cannot","couldn't":"could not"}

words = tweet.split()

for word in words:
    for k in apostrophes.keys():
       if k in word:
           word = word.replace(k,apostrophes.get(k))
       else:
           pass

Answer 1

无需分割单词并循环遍历它们：

tweet = "you're his i'm couldn't can't won't it's"
apostrophes = {"'s":" is","'re":" are","'ll":" will","'d":" would","i'm":"I am","I'm":"I am","won't":"will not", "'ve":" have","can't":"cannot","couldn't":"could not"}

for k, v in apostrophes.iteritems():
    tweet = tweet.replace(k, v)

print tweet # you are his I am could not cannot will not it is

（请注意，这是python 2.7）
