检验合并电影的时长

# 计算电影的总时长，检验是否与合并视频的时长一致
# 电影拖到最后看是几个小时，几分钟
# n = 0
# with open("second_m3u8.txt", mode="r", encoding='utf-8') as f:
#     for line in f:
#         if line.startswith("#EXTINF:"):
#             line = line.strip()
#             line = line.strip(",")
#             n += float(line.split(":")[-1])  # 通过：去切，切完取-1
# print(n)  # 得到电影的总时长
n = 7857
print(n / 60)  # n 除以60
print(126.45 % 60)  # % 余上
