python - 如何在列表中的字典字符串中搜索单词？

Question

def SearchEntryComment():
    print("\n\nSearch for guestbook comment with a keyword\n")
    CommentSearch = input("Enter key word for search: ")
    for i in range(len(dlGuestBook)):
        if CommentSearch in dlGuestBook[i]["Comment"]:
            print(i+1, ".", dlGuestBook[i] ["FirstName"], dlGuestBook[i]["LastName"], dlGuestBook[i]["Date"])
            print(dlGuestBook[i]["Comment"], "\n")
        else:
            print("No results found")
    print("\n")

这是我当前的代码，但是当我对列表中的每个元素运行它时，它将打印“未找到结果”，如果存在，它将打印该结果。我希望它要么打印存在的结果，要么打印没有找到的结果。

仅使用resultCount来保存列表中找到的结果的计数，并在for循环后检查计数。

def SearchEntryComment():
    print("\n\nSearch for guestbook comment with a keyword\n")
    CommentSearch = input("Enter key word for search: ")
    resultCount = 0
    for i in range(len(dlGuestBook)):
        if CommentSearch in dlGuestBook[i]["Comment"]:
            print(i+1, ".", dlGuestBook[i] ["FirstName"], dlGuestBook[i]["LastName"], dlGuestBook[i]["Date"])
            print(dlGuestBook[i]["Comment"], "\n")
            resultCount += 1
    if resultCount == 0:
        print("No results found")
    print("\n")
