python - 為什麼提取不到url編碼的資料？

Question

這是我的程式碼

            source_ip = line.split(' ')[11].strip()
            if re.match('[\%\w]+',source_ip):
                if source_ip_dict.get(source_ip,'-')=='-':
                    source_ip_dict[source_ip]=1
                else:
                    source_ip_dict[source_ip]=source_ip_dict[source_ip]+1

這是日誌裡面的資料
