Question

这是我的代码段

import json
import difflib
from difflib import get_close_matches

definitions = json.load(open("data.json"))

def thesaurus(words):
    if words in definitions:
        return definitions[words]
    elif len(get_close_matches(words, definitions.keys())) > 0:
        yn = input("Did you mean %s instead? Enter 'Y' if yes or 'N' if no: " % get_close_matches(words,definitions.keys()) [0])
        if yn == "Y":
            return thesaurus[get_close_matches(words, definitions.keys())]
        elif yn == "N":
            return "None found"
    else:
        return "Please check word again"


words = input("Look Up: ").lower()

print(thesaurus(words))

我希望收到“悲伤”一词的含义。但是，我一直收到错误消息：函数对象不可下标。

这里是终端日志，以防万一它可能会帮助您：

My-MacBook-Pro:Python Adwok$ python3 dictionary.py
Look Up: GRERFAG
Did you mean grief instead? Enter 'Y' if yes or 'N' if no: Y
Traceback (most recent call last):
  File "dictionary.py", line 22, in <module>
    print(thesaurus(words))
  File "dictionary.py", line 13, in thesaurus
    return thesaurus[get_close_matches(words, definitions.keys())]
TypeError: 'function' object is not subscriptable

请指出即使是最小的细节，我也非常感谢。

如错误堆栈所述，在第13行中，您正在访问thesaurus，就好像它是一个列表/字典（或任何可下标的对象）一样。由于thesaurus是一个函数（不可下标），因此会出现错误。因此，您需要调用该函数（而不是访问它）：

thesaurus(get_close_matches(words, definitions.keys()))

另外，您应该注意：

在代码末尾，您可以通过调用thesaurus

print(thesaurus(words))

请考虑重用get_close_matches的结果，以避免多次调用同一函数（如果该调用消耗资源，则可能导致性能下降）。

我建议您采用以下解决方案：

import json
import difflib
from difflib import get_close_matches

definitions = json.load(open("data.json"))

def thesaurus(words):
    if words in definitions:
        return definitions[words]
    else:
        close_matches = get_close_matches(words, definitions.keys())
        if len(close_matches) > 0:
            yn = input("Did you mean %s instead? Enter 'Y' if yes or 'N' if no: " % get_close_matches(words,definitions.keys()) [0])
            if yn == "Y":
                return thesaurus(close_matches)
            elif yn == "N":
                return "None found"
        else:
            return "Please check word again"


words = input("Look Up: ").lower()

print(thesaurus(words))

为什么会收到错误消息“'函数'对象不可下标'
