老师我运行你得第一周第三节的课后作业的代码，怎么会出现这些信息，这是为什么呢
在第一章第二节课的时候运行出现
C:\Users\lenovo\AppData\Local\Programs\Python\Python35-32\python.exe C:/Users/lenovo/PycharmProjects/web/web.py
Traceback (most recent call last):
File "C:/Users/lenovo/PycharmProjects/web/web.py", line 4, in <module>
Soup=BeautifulSoup(wb_data,'lxml')
File "C:\Users\lenovo\AppData\Local\Programs\Python\Python35-32\lib\site-packages\bs4\__init__.py", line 165, in __init__
% ",".join(features))
bs4.FeatureNotFound: Couldn't find a tree builder with the features you requested: lxml. Do you need to install a parser library?
Process finished with exit code 1
这种情况不知道如何改进
第三节课的内容的疑惑
def get_attraction(url,data=None):
这个函数的参数里为什么要写data =None?
写和不写有什么区别么？
