AttributeError sorununu giderme: 'NoneType' nesne piton hiçbir özelliği 'ni kodlamak' Ben alıyorum

Question

for comment_entry in comment_feed.entry: 
content = comment_entry.ToString() 
parse = BeautifulSoup(content) 
for con in parse.find('ns0:content'): 
    print con.string 
    s = con.string 
    file.write(s.encode('utf8')) 

Hata vardır:

File "channel_search.py", line 108, in youtube_search 
file.write(s.encode('utf8')) 
AttributeError: 'NoneType' object has no attribute 'encode' 

Answer 1

Sizin s olabilir NoneType

deneyin

s = con.string 
if s:file.write(s.encode('utf8')) 
# or if s is not None   
#if you want to check only for None
