我的代碼一天比一天大，現在我想把它分成模塊。但我在變量方面遇到了麻煩。問題在于，我不應該在哪里聲明變量，或者導入內置模塊：在我的自定義模塊中，或者.這是我的代碼：views.pyviews.pyviews.py:@login_required(login_url='sign_in')def result(request): find_by_fives() context = { 'last_uploaded': last_uploaded, 'words_count': words_count, 'characters_count': characters_count } return render(request, 'result.html', context)find_by_fives.py（是我的自定義模塊）：import glob from .models import OriginalDocumentfrom django.shortcuts import renderdef find_by_fives(): last_uploaded = OriginalDocument.objects.latest('id') original = open(str(last_uploaded.document), 'r') original_words = original.read().lower().split() words_count = len(original_words) open_original = open(str(last_uploaded.document), "r") read_original = open_original.read() characters_count = len(read_original) path = 'static/other_documents/doc*.txt' files = glob.glob(path) 錯誤：NameError: name 'last_uploaded' is not defined注意：這不是我的全部觀點，我只想知道我應該在哪里聲明，變量和導入。context

好的，我看到了 - “find_by_fives.py”是一個功能，對吧？因此，您在其中聲明的變量僅存在于其中。因此，當您從 views.py 調用此函數時 - 它們被聲明，然后，當函數結束時，它們將被刪除。如果要在 views.py 中使用它們 - 您應該返回它們并在那里分配一個變量，然后將它們傳遞給上下文：
@login_required(login_url='sign_in')
def result(request):
last_uploaded, words_count, characters_count = find_by_fives()
context = {
'last_uploaded': last_uploaded,
'words_count': words_count,
'characters_count': characters_count
}
return render(request, 'result.html', context)
def find_by_fives():
last_uploaded = OriginalDocument.objects.latest('id')
original = open(str(last_uploaded.document), 'r')
original_words = original.read().lower().split()
words_count = len(original_words)
open_original = open(str(last_uploaded.document), "r")
read_original = open_original.read()
characters_count = len(read_original)
path = 'static/other_documents/doc*.txt'
files = glob.glob(path)
return last_uploaded, words_count, characters_count
