使用文本文件創建字典時出現問題，該字典以字長為鍵，實際字本身為 Python 中的值

Question

我目前是 Python 的初學者，正在參加 Python 的入門課程，我在創建一個劊子手游戲時遇到了麻煩，在該游戲中，我們從一個文本文件中導出我們的單詞，每個單詞都打印在一個新行上，然后我們在function 根據用戶指定的字長隨機選擇一個字。 我不確定我們應該怎么做，我已經上傳了我當前的代碼，問題是當我打印出字典時，只有文本文件中的單詞實際被打印出來，我不確定為什么字典鍵和值沒有被打印出來......我也不確定為什么我的教授希望我們嘗試一下，除了這個 function 以及我應該如何使用 max_size。

這是我目前所做的

def import_dictionary (dictionary_file):
    dictionary = {}
    max_size = 12
    with open ('dictionary.txt', 'a+') as dictionary:
        dictionary_file = dictionary.read().split()
        for word in dictionary_file:
            dictionary[len(word)] = word
    return dictionary

我用來打印的 function

def print_dictionary (dictionary):
    max_size = 12
    with open('dictionary.txt', 'r') as dictionary:
        print(dictionary.read())

Answer 1

嘗試以下操作：

def import_dictionary(dictionary_file):
    dictionary = {}
    max_size = 12
    with open(dictionary_file, 'r') as f:
        words = f.read().split('\n')  # each word is on new line so split on newline: '\n'
        for word in words:
            length = len(word)
            if length > max_size:    # If word too long, ignore it
                continue
            elif dictionary.get(length) is not None:
                dictionary[length].append(word)  # If dict already has entry for word length, append word.
            else:
                dictionary[length] = [word] # Otherwise create entry
    return dictionary

嘗試這個。

from collections import defaultdict
import random

def read_text_file():
    words = defaultdict(list)
    with open("file.txt","r") as f:
        text_file = f.read()
    text_file = text_file.split("\n")
    for wrd in text_file:
        words[len(wrd)].append(wrd)
    return words

def main():
   user_length = int(input())
   words = read_text_file()
   shuffle_words = random.sample(words[user_length])
   print(shuffle_words[0])
