Python：有没有可能压缩我的类似方法列表

我有一个使用Selenium IDE捕获的ID列表，并将它们放入PyCharm中。列表如下所示：

filter_logs_query = (By.ID, "Query")
filter_logs_FromDateUI = (By.ID, "FromDateUI")
filter_logs_ToDateUI = (By.ID, "ToDateUI")
filter_logs_Ip = (By.ID, "Ip")
filter_logs_User = (By.ID, "User")  
filter_logs_Message = (By.ID, "Message")
filter_logs_RefID = (By.ID, "Refid")
filter_logs_Session = (By.ID, "Session")
filter_logs_Scope = (By.ID, "Scope")
filter_logs_EventNo = (By.ID, "EventNo")
filter_logs_Server = (By.ID, "Server")

def filter_logs_search_query(self, word):
    search_text = self.driver.find_element(*Elements.filter_logs_query)
    search_text.send_keys(word)

def filter_logs_logged_after(self, word):
    search_date = self.driver.find_element(*Elements.filter_logs_FromDateUI)
    search_date.send_keys(word)

def filter_logs_logged_before(self, word):
    search_date = self.driver.find_element(*Elements.filter_logs_ToDateUI)
    search_date.send_keys(word)

每个ID都有一个def供用户向ID发送密钥，列表如下所示：

filter_logs_query = (By.ID, "Query")
filter_logs_FromDateUI = (By.ID, "FromDateUI")
filter_logs_ToDateUI = (By.ID, "ToDateUI")
filter_logs_Ip = (By.ID, "Ip")
filter_logs_User = (By.ID, "User")  
filter_logs_Message = (By.ID, "Message")
filter_logs_RefID = (By.ID, "Refid")
filter_logs_Session = (By.ID, "Session")
filter_logs_Scope = (By.ID, "Scope")
filter_logs_EventNo = (By.ID, "EventNo")
filter_logs_Server = (By.ID, "Server")

def filter_logs_search_query(self, word):
    search_text = self.driver.find_element(*Elements.filter_logs_query)
    search_text.send_keys(word)

def filter_logs_logged_after(self, word):
    search_date = self.driver.find_element(*Elements.filter_logs_FromDateUI)
    search_date.send_keys(word)

def filter_logs_logged_before(self, word):
    search_date = self.driver.find_element(*Elements.filter_logs_ToDateUI)
    search_date.send_keys(word)

除了需要从*元素调用的函数外，我的def几乎相同。有没有办法压缩/缩短def列表

是的。您已经在发送密钥类型为的字符串。使用if语句或制作使用字符串作为键的字典

在构造函数中定义字典：

def __init__(self):
    self.query_map = {'Message':Elements.filter_logs_mesage, 'Session':Elements.filter_logs_session} # etc

然后使用字典“选择”元素：

    def filter_logs_search(self, word):
        search_text = self.driver.find_element(self.query_map[word]) 
search_text.send_keys(word)

这是我的工作

每当您遇到代码相同的情况时，除了调用一个函数外，最好只传入该函数（注意

f

）：

然后，其他函数可以用广义高阶函数来定义。例如：

def filter_logs_search_query(self, word):
    general_filter_logs(word, Elements.filter_logs_query)

注意，你的重复函数不是很大，所以这里的增益不是很大。不过，这种技术对于更复杂的函数尤其有用。泛化函数的好处是，如果需要对其进行更改，只需更改一个函数（通用函数），而不是所有“克隆”函数

还请注意，这似乎是

find_元素

使用的技术！它不强制您编写自己的自定义查找方法，而是允许您只传入一个函数。你现在需要做的就是推回谁负责挑选传递的函数的责任

看起来整个东西都可以压缩到

class FilterClass:
    fields = {
        "query": "Query",
        "before": "FromDateUI",
        "after": "ToDateUI",
        "ip": "Ip",
        "user": "User",
        "msg": "Message",
        "ref": "Refid",
        "session": "Session",
        "scope": "Scope",
        "event": "EventNo",
        "server": "Server"
    }

    def filter_logs(self, field, value):
        search = self.driver.find_element(By.ID, self.fields[field])
        search.send_keys(value)

创建一个包含所有公共代码的函数，并将不同的函数作为参数传入。如果你问我，拥有这些

def

语句一点也不坏。你有很好的函数名来描述完成的工作。
