Question

我想知道如何将输入中的单词转换为Python中的值。用户可以输入输入，例如：

"The dog chased the cat the lion chased the dog"

我希望它返回：

["1,2,3,1,4,1,5,6,1,2"]

我希望重复的单词保留与单词首次出现时相同的值。我试过多种方式，我现在使用下面的代码，但它似乎返回随机索引：

l = input("Enter a sentence").lower lists= list(l) valueindex = range(len(lists)) print(valueindex)

感谢您的帮助，艾萨克

Answer 1

def text_process(text):
    '''split text to list and all the item are lower case'''

    text_list = text.lower().split()
    return text_list

def lookup_table(text_list):
    '''build dict contain the text and number pair'''

    lookup = {}
    start = 0
    for item in text_list:
        if item not in lookup:
            lookup[item] = start + 1
            start += 1
    return lookup

if __name__ == '__main__':
    text = "The dog chased the cat the lion chased the dog"
    text_list = text_process(text)
    lookup_table = lookup_table(text_list)
    out_put = [lookup_table[text]for text in text_list]
    print(out_put)

出：

[1, 2, 3, 1, 4, 1, 5, 3, 1, 2]
