I have a dataframe that just contains times in a string format (dtype: object). What I wanted to know is how can I create a new column that contains the time interval that the row coincides in? I've provided some sample data below:

```
    Loss Time
0   02:10
1   22:20
2   20:00
3   01:20
4   12:36

```

I want to create a column that contains the interval 10AM-4PM, 4PM-8PM, 8PM-6AM and 6AM-10AM. I've tried multiple different ways but haven't found any success. the pandas between\_time function doesn't work as it needs the index as a datetime index which I can't do and I've tried looking at strptime but had no success there. Any ideas would be much appreciated.
