当我使用的较新版本的库使用不同的函数名称时，如何解决硬编码？ -蟒蛇
[英]How to resolve the hardcoding when a newer version of the library i use uses a different function name? - python
问题描述
Is there a better way to resolve the problem of hardcoding compatiable code when a library i use uses a different name of the function? 
当我使用的库使用函数的其他名称时，是否有更好的方法来解决对兼容代码进行硬编码的问题？
Also, I cannot change the library code. 另外， 我无法更改库代码。 (because that function i'm using is EVERYWHERE in the old version of the code). （因为在旧版本的代码中，我正在使用的功能无处不在）。 The library is BeautifulSoup 3 and 4. see Method Name section in http://www.crummy.com/software/BeautifulSoup/bs4/doc/ 该库为BeautifulSoup 3和4。请参见http://www.crummy.com/software/BeautifulSoup/bs4/doc/中的“ Method Name部分。
Originally, i have bs4 code, but my users have bs3, so i have to put the following code everywhere: 本来我有bs4代码，但我的用户有bs3，所以我必须将以下代码放在各处：
try:
from bs4 import BeautifulSoup as bs
except:
from BeautifulSoup import BeautifulSoup as bs
page = '''<html>foo bar<p>blah blah black sheep</p> bar</html>'''
try:
p = bs(page).find_all('p')
except: # Imagine i have to do this all over my code that uses `find_all` or `findAll`
p = bs(page).findAll('p')

May be you should just monkey-patch the bs: 可能是您应该对bs进行猴子补丁处理：
try:
from bs4 import BeautifulSoup as bs
except:
from BeautifulSoup import BeautifulSoup as bs
bs.find_all = getattr(bs, 'find_all', False) or getattr(bs, 'findAll')
