Like the pandas df data above, I want to transform it into an hourly line, but due to irregular grouping, resample('H') cannot be used
For example, from 21:00-22:00, 22:00-23:00, 23:00-9:30, 9:30-10:45 such customized group summary
Please tell me how to implement it, thank you

Write a class to define the content field of the hour line
Then read the tuple line by line and record the ohlc of the hour line
Generate a new bar if the time meets the conditions
