Question

有人能告诉我如何在程序找到后从列表中打印这个单词吗？

all_text = input("Please enter some text").lower().split()
keyword_list = ["motorcycle","bike","cycle","dirtbike"]
second_list = ["screen","cracked","scratched"]

if any(word in keyword_list for word in all_text):
    print("Keyword found")
    if any(word in second_list for word in all_text):
        print("Keyword found")
elif any(word in second_list for word in all_text):
    print("keyword found")

Answer 1

如果我正确阅读此内容，那么如果它在以太list中，则需要相同的内容。如果你想拆分它，你可以做elif。

all_text = input("Please enter some text").lower().split()

keyword_list = ["motorcycle","bike","cycle","dirtbike"]

second_list = ["screen","cracked","scratched"]


for word in all_text:
  if word in second_list or word in keyword_list:
    print("Keyword found " + word)

Answer 2

使用普通for循环比any更容易执行此任务

all_text = input("Please enter some text").lower().split()
keyword_list = ["motorcycle","bike","cycle","dirtbike"]
second_list = ["screen","cracked","scratched"]

for word in all_text: 
    # note that you can't use word in keyword_list 
    # because it'll also match bike with dirtbike etc.
    for keyword in keyword_list:
        if word == keyword:
            print("Word " + word + "in first keyword list")
            break

    for keyword in second_list:
        if word == keyword:
            print("Word " + word + "in second keyword list")
            break

Answer 3

您似乎已经掌握了Python中in的使用方法，但对于未来的读者，我会注意到Python的in可用于隐式搜索列表和比较两个列表中的元素时避免第二个for循环。

all_text = input("Please enter some text").lower().split()
keyword_list = ["motorcycle","bike","cycle","dirtbike"]
second_list = ["screen","cracked","scratched"]

for word in all_text: 
    if word in keyword_list:
        print("Word '{}' found in keyword_list".format(word))
    elif word in second_list:
        print("Word '{}' found in second_list".format(word))

＆＃34;有谁能告诉我如何打印这个词（...）＆＃34; ？

Python支持至少三种动态创建字符串的方法......

一个printf - ish风格，对于C编码员来说可能看起来很熟悉：

>>> "Inserted word: %s" % "Hi!"
'Inserted word: Hi!'
>>>

使用str s format方法：

>>> "Inserted word: {}".format("Hi!")
'Inserted word: Hi!'
>>>

（Ab）使用+运算符：

>>> "Inserted word: " + "Hi!"
'Inserted word: Hi!'
>>>
