I have data in the format:

0    20:30
1    17:05
2    17:28
3    14:12
4    19:58
..     ...
176  15:57
177  19:02
178  17:52
179  19:39

And it’s Dtype is Str type. How can I convert this str type (hour, minute) data into int type and use only the time part separately?

How can I convert this str type (hour, minute) data into int type and use only the time part separately?

>Solution :

def str_to_int_list(mylist):
   newlist = []
   for value in mylist:
       hr, min_ = value.split(":")
       newlist.append(int(hr)*60+int(min_))
   return newlist
