毎回調べ直すので、備忘用...
timedelta、いい感じにフォーマットできないので、
自分で計算しないといけない....
def format_timedelta(timedelta): total_sec = timedelta.total_seconds() # hours hours = total_sec // 3600 # remaining seconds remain = total_sec - (hours * 3600) # minutes minutes = remain // 60 # remaining seconds seconds = remain - (minutes * 60) # total time return '{:02}:{:02}:{:02}'.format(int(hours), int(minutes), int(seconds))
