python判断文件是否存在

os.path.exists(file_path):

python多线程

p1 = threading.Thread(target=down)
t1 = threading.Thread(target=crawl)

print("启动")
p1.start()

t1.start()
print("join")
p1.join()
t1.join()

python多线程与redis控制多线程的数量

    while True:
        try:
            if threading.active_count() > 10:
                time.sleep(10)
            else:
                data1 = r1.get("cartoon_data")
                if data1 is None:
                    time.sleep(10)
                    continue
                else:
                    data = json.loads(data1)
                    file_path= data.get("file_path")
                    ts_urls= data.get("ts_urls")
                    if os.path.exists(file_path):
                        continue
                    t1 = threading.Thread(target=download_ts, args=(ts_urls, file_path))
                    t1.start()
                    t1.join()
                    print(t1.name)
        except Exception as e:
            print("eeee",e.args)
            pass

python 两个列表中有重复元素,去重且合并

t11 = url2.split("/")
t22 = re_s.split("/")
t33 = t11 + t22
for tmp in t11:
    if (tmp in t22):
        t22.remove(tmp)

python redis工具类

class Redis:

    def __init__(self,db):

        self.r = redis.StrictRedis(host="x", db=db)

    def lpush(self,key,values):
        self.r.lpush(key,values)

    def get(self,key):
        return  self.r.rpop(key)

    def __del__(self):
        self.r.close()

python m3u8

#EXTM3U
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=800000,RESOLUTION=1080x608
2000k/hls/mixed.m3u8


这个文件没有ts文件

需要将2000k/hls/mixed.m3u8 url拼接重新获取一个m3u8文件,之后会获取到带有ts字段的内容,然后url拼接,requests请求,获取响应的内容,将内容拼接在一起,写入到文件,最后得到完整的视频文件
