Question

我有这样的Python列表：

[].find

现在，我想在列表中使用多个关键字进行搜索，例如：

当我尝试输入关键字老师和销售

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

它应该返回如下结果：

学校老师
数学老师
销售员
销售经理

到目前为止，我已经编写了这样的代码：

input keywords: teacher sales

但是当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，它才有效。

那么，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，可以使用以下列表理解将其压缩成一个很好的单行代码：

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

两者都做同样的事情，并给出如下输出结果

[“销售员”，“销售经理”，“学校老师”，“数学” 老师']

祝你好运！

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，然后再将其提供给函数

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

您可以尝试

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
