Question

我需要在循环中包含三个特定特定子字符串的URL。以下代码有效，但我确信有更优雅的方法：

for node in soup.findAll('loc'):
    url = node.text.encode("utf-8")
    if "/store/" not in url and "/cell-phones/" not in url and "/accessories/" not in url:
        objlist.loc.append(url) 
    else:
        continue

谢谢！

Answer 1

url = node.text.encode("utf-8")    
sub_strings = ['/store','/cell-phones/','accessories']

if not any(x in url for x in sub_strings):
    objlist.loc.append(url)
else:
    continue

来自docs：

如果iterable的任何元素为true，则

any返回True。如果iterable为空，则返回False。相当于：

def any(iterable):
    for element in iterable:
        if element:
            return True
    return False

在Python中使用多个NOT IN语句
