我正在尝试翻译。

english_List = ["fire","apple","morning","river","wind"]
spanish_List = ["fuego","manzana","mañana","río","viento",]

输入英文单词时,我是否可以这样做,例如"fire"它会打印出相应的翻译"fuego"

使用字典。您可以创建一个字典,其中映射了英语单词 使用zip()"fire""fuego""apple""manzana"联系起来,使用这两个列表中的相应西班牙语单词,依此类推。然后使用dict()构建字典。

english_list = ["fire","apple","morning","river","wind"]
spanish_list = ["fuego","manzana","mañana","río","viento"]

english_to_spanish = dict(zip(english_list, spanish_list))

您可以获得英语单词的翻译,然后:

spanish = english_to_spanish['apple']

如果找不到单词,则会引发KeyError异常。一个更完整的例子可以使用一个函数进行翻译,比如说:

def translate(english_word):
    try:
        print("{} in Spanish is {}".format(
            english_word, english_to_spanish[english_word]))
    except KeyError:
        print("Looks like Spanish does not have the word for {}, sorry"
            .format(english_word))

while True:
    word = input()  # raw_input in python 2
    translate(word)

使用dict映射相应的单词:

trans_dict = {"fire":"fuego","apple":"manzana","morning":"mañana","river":"río","wind":"viento"}

inp = raw_input("Enter your english word to translate:").lower()
print("{} is {}".format(inp.capitalize(),trans_dict.get(inp," not in my translation dict").capitalize()))

您可以使用zip从列表中制作字典:

english_List = ["fire","apple","morning","river","wind"]
spanish_List = ["fuego","manzana","mañana","río","viento"]
trans_dict = dict(zip(english_List,spanish_List))

使用默认值为trans_dict.get(inp,"not in my translation dict")的{​​{1}}将确保用户输入我们的"not in my translation dict"中不存在的字词,它会打印trans_dict和避免使用the_word is not in my translation dict"

我们使用keyError以防用户使用大写字母输入Fire或Apple等..并使用.lower()输出数据大写。

dict.get

您可以使用此功能执行此操作:

def translate(word, english_list, spanish_list):
    if word in english_list:
        return spanish_list[english_list.index(word)]
    else:
        return None

但是,正确的方法是使用字典。

我认为最好的方法是使用字典。 例如:

d = {"fire": "fuego", "apple": "manzana"}

然后检索翻译:

d.get("fire", "No translation")
