Issue With the imports in SearchResultPages.py file

[ThatDevCoder]

I have replaced the code in SearchResultPages.py with the data in SearchResultPages.py file My updated code looks like this ` SearchEngines = { 'google': 'https://www.google.com/search?q={0}&start={1}', 'bing': 'http://www.bing.com/search?q={0}&first={1}', 'baidu': 'http://www.baidu.com/s?wd={0}&pn={1}' }

SearchEngineResultSelectors= { 'google': '//h3/a/@href', 'bing': '//h2/a/@href', 'baidu': '//h3/a/@href', }

class SearchResultPages: totalPage = 0 keyword = None, searchEngineUrl = None currentPage = 0 searchEngine = None

def __init__(self, keyword, search_engine, total_page):
    self.searchEngine = search_engine.lower()
    self.searchEngineUrl = SearchEngines[self.searchEngine]
    self.totalPage = total_page
    self.keyword = keyword

def __iter__(self):
    return self

def _currentUrl(self):
    return self.searchEngineUrl.format(self.keyword, str(self.currentPage * 10))

def next(self):
    if self.currentPage < self.totalPage:
        url = self._currentUrl()
        self.currentPage = self.currentPage + 1
        return url
    raise StopIteration

`

But still, I'm getting an error message
