【问题描述】:
在其他一些教程中,以下 python 代码用于从适用于它们的 json 文件中查找单词。但是,不适合我。 你能帮我摆脱这个错误吗?
import json
from difflib import get_close_matches
data = json.load(open("data.json"))
def translate(word):
word = word.lower
if word in data:
return data[word]
elif len(get_close_matches(word, data.keys())) > 0:
yn=input ("did you mean %s instead? Enter Y if yes and N if no" % get_close_matches(word, data.keys())[0])
if yn == "Y":
return data[get_close_matches(word, data.keys())[0]]
elif yn == "N":
return("the word doesn't exist")
else:
print("we don't understand your entry")
else:
return("the word does't exist please crosscheck it")
word = input("enter a word: ")
output = translate(word)
if type(output) == list:
for item in output:
print(item)
else:
print(output)
这是我得到的错误:
Traceback (most recent call last):

output = translate(word)
File "pracjson.py", line 10, in translate
