用#34; SAD"替换表情符号的代码或者" HAPPY"不正常

所以我想用“HAPPY”取代所有快乐的表情符号,反之亦然“SAD”用于文本文件的悲伤表情符号。但代码不能正常工作。虽然它检测到表情符号(截至目前:-)),但在下面的例子中它没有用文本替换表情符号,它只是附加文本而且它也附加了两次,原因我似乎不理解。

dict_sad={":-(":"SAD", ":(":"SAD", ":-|":"SAD",  ";-(":"SAD", ";-<":"SAD", "|-{":"SAD"}
dict_happy={":-)":"HAPPY",":)":"HAPPY", ":o)":"HAPPY",":-}":"HAPPY",";-}":"HAPPY",":->":"HAPPY",";-)":"HAPPY"}

#THE INPUT TEXT#
a="guys beautifully done :-)" 

for i in a.split():
    for j in dict_happy.keys():
        if set(j).issubset(set(i)):
            print "HAPPY"
            continue
    for k in dict_sad.keys():
        if set(k).issubset(set(i)):
            print "SAD"
            continue
    if str(i)==i.decode('utf-8','replace'):
       print i

输入文本

a="guys beautifully done :-)"              

OUTPUT(“HAPPY”即将播出两次,表情符号也不会消失)

guys
-
beautifully
done
HAPPY
HAPPY
:-)

预期输出

guys
beautifully
done
HAPPY

您正在将每个单词每个表情符号转换为一个集合;这意味着您正在寻找单个字符的重叠。您可能希望最多使用完全匹配:

for i in a.split():
    for j in dict_happy:
        if j == i:
            print "HAPPY"
            continue
    for k in dict_sad:
        if k == i:
            print "SAD"
            continue

您可以直接迭代字典 ,无需在那里调用.keys()。你实际上似乎没有使用字典值;你可以这么做:

for word in a.split():
    if word in dict_happy:
        print "HAPPY"
    if word in dict_sad:
        print "SAD"

然后可能使用集而不是字典。然后可以将其简化为:

words = set(a.split())
if dict_happy.viewkeys() & words:
    print "HAPPY"
if dict_sad.viewkeys() & words:
    print "SAD"

使用键上的dictionary view作为一组。尽管如此,使用套装仍然会更好:

sad_emoticons = {":-(", ":(", ":-|", ";-(", ";-<", "|-{"}
happy_emoticons = {":-)", ":)", ":o)", ":-}", ";-}", ":->", ";-)"}

words = set(a.split())
if sad_emoticons & words:
    print "HAPPY"
if happy_emoticons & words:
    print "SAD"

如果您想从文字中删除表情符号,则必须过滤单词:

for word in a.split():
    if word in dict_happy:
        print "HAPPY"
    elif word in dict_sad:
        print "SAD"
    else:
        print word

或者更好的是,结合两个词典并使用dict.get()

emoticons = {
    ":-(": "SAD", ":(": "SAD", ":-|": "SAD", 
    ";-(": "SAD", ";-<": "SAD", "|-{": "SAD",
    ":-)": "HAPPY",":)": "HAPPY", ":o)": "HAPPY",
    ":-}": "HAPPY", ";-}": "HAPPY", ":->": "HAPPY",
    ";-)": "HAPPY"
}

for word in a.split():
    print emoticons.get(word, word)

这里我将当前单词作为查找键和默认值传递;如果当前单词不是表情符号,则会打印单词本身,否则会打印单词SADHAPPY

我没有使用词典,而是使用了列表。使代码更简单:

list_sad = [":(", ":-("]
list_happy = [":)", ":-)"]

a = "guys beautifully done :-)" 

for i in a.split():
    if i in list_sad:
        print ("SAD")
    elif i in list_happy:
        print ("HAPPY")
    else:
        print (i)
