Python在列表中搜索多个单词

Question

我有这样的Python列表：

['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']

现在，我想在列表中搜索多个关键字，例如：

当我尝试输入关键字教师和销售时

input keywords: teacher sales

它应该返回如下结果：

• 教师
• 数学老师
• 售货员
• 销售经理

到目前为止，我已经编写了如下代码：

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']

def search_multiple_words(search_words):
    search_words = [search_words]

    for line in job_list:
        if any(word in line for word in search_words):
            print(line)

search_words = input("input keywords: ")
search_multiple_words(search_words)

但是它只在我输入一个关键字而不是上面我给出的示例的多个关键字时才有效。

那么，该怎么做..？

Answer 1

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager',
            'sales manager', 'schoolteacher', 'mathematics teacher']


def search_multiple_words(search_words):
    search_words = search_words.split(' ')

    out = [s for s in job_list if any(xs in s for xs in search_words)]
    print(out)


search_words = input("input words: ")
search_multiple_words(search_words)

Answer 2

您可以使用find（）方法。 这应该为您工作：

lis=['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']
str1 = ["teacher", "sales"]
x=[]
for y in lis:
    for string in str1:
        if y.find(string) != -1:
            x.append(y)

上面的代码用于可读性和可理解性 。 但是，可以使用以下列表推导将其压缩为一个不错的单行代码：

x = [y for y in lis for string in str1 if y.find(string) != -1]

两者都做同样的事情，并给出这样的输出

[“销售人员”，“销售经理”，“学校老师”，“数学老师”]

祝好运！

Answer 3

正如Adrian Shum所说，您的输入为您提供了一个字符串。 您需要先对其进行拆分，然后再将其提供给功能

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 'sales manager', 'schoolteacher', 'mathematics teacher']

def search_multiple_words(search_words):
    # Not neecssary anymore as you're feeding a list
    # search_words = [search_words]

    for line in job_list:
        if any(word in line for word in search_words):
            print(line)

search_words = input("input keywords: ").strip().split()
search_multiple_words(search_words)

Answer 4

你可以试试这个

job_list = ['assistant manager', 'salesperson', 'doctor', 'production manager', 
            'sales manager', 'schoolteacher', 'mathematics teacher']

def search_multiple_words(search_words):
    search_words = [search_words]

    for line in job_list:
        if any(word in line for word in search_words):
            print(line)

search_words = input("input keywords: ").split(' ')
for w in search_words:
    search_multiple_words(w)

输出：

input keywords: sales teacher
salesperson
sales manager
schoolteacher
mathematics teacher
