gui를 이용한 알람시계를 구현하고 싶은데 알람을 설정하면 아래와 같은 에러들이 생성됩니다. 아래의 에러는 알람시간을 오전 00시부터 09시로 설정했을 때 생기는 에러입니다.

self.alarm_h = int(alarm_time[19:21]) #value of hour is sotred in index value 19 and 20
ValueError: invalid literal for int() with base 10: '0,'

아래는 00분부터 09분까지 알람을 설정했을 때 생기는 에러입니다.

self.alarm_m = int (alarm_time[23:25]) #value of minute is sotred in index value 23 and 24
ValueError: invalid literal for int() with base 10: '0,'

시간 값을 인덱스를 19에서 21로 설정하고 분 값을 23에서 25로 설정하는 것인데 이 인덱스를 코드 어디부분에서 받아오는 것인지 모르겠습니다.
