Question

以下是该模块的链接：https://github.com/danieliu/play-scraper

我希望从Google Play商店中抓取某个项目的收藏集。

我运行以下代码。

import play_scraper
print play_scraper.collection(
        collection='COMMUNICATION',
        category='TOP COMMUNICATION APPS',
        results=5,
        page=1

跟踪：

SyntaxError: in File "Play-scrape.py", line 2, in <module>
             print  play_scraper.collection(
                             ^

更新

我在运行代码时使用python3，并更新了我的打印语句以包括方括号。

现在我收到错误

我是python和脚本的新手，关于如何在此问题上取得进展的任何建议将不胜感激。我知道这是一个基本问题，对于在其他地方容易解决的问题，我们深表歉意。

-注意：最初对语法有所帮助，因为我没有按照python3语法添加括号，并且收到语法错误。我现在在终端中返回此错误。

Answer 1

您可能正在使用python 3.x，其中print statements need brackets

尝试

print(play_scraper.collection(
      collection='COMMUNICATION',
      category='TOP COMMUNICATION APPS',
      results=5,
      page=1))

第二期

尝试运行

pip3 install play-scraper -U

确保您具有最新要求。注意pip -> python2.x, pip3 -> python3.X

使用Python Play-Scraper模块-无法使用模块检索数据
