  • Given a list of (date, duration) tuples, how would you filter by time period and calculate summary stats (average, rolling sum)?
  • Suppose we have a dataset of (date, duration) tuples. How would you filter by a specific time period and then generate summary statistics, including the average duration and rolling sum, for each date within that time period?
  • How would you approach the task of filtering by time period and calculating summary statistics (average, rolling sum) from a dataset of (date, duration) tuples?
  • Given a set of (date, duration) tuples, how would you filter by a specific date range and then compute the average duration and rolling sum for each date within that range?
  • Suppose we have a dataset of (date, duration) tuples. Explain how you would filter by a particular time period and analyze the data to produce summary statistics such as the average duration and rolling sum?
  • Can you walk me through how you would filter data by time period in a set of (date, duration) tuples and compute some summary statistics such as the average duration and rolling sum?
  • Let's imagine we have a list of (date, duration) tuples. How would you filter by a specific time frame and then calculate summary stats like the average duration and rolling sum?
  • Given a list of (date, duration) tuples, what is your process for filtering by time period and then calculating summary statistics such as the average duration and rolling sum?
  • How would you extract and compute summary statistics such as the average duration and rolling sum from a set of (date, duration) tuples that have been filtered by a particular time period?
  • Given a dataset of (date, duration) tuples, can you demonstrate how you would filter the data within a specific time frame and calculate the average duration and rolling sum for each date within that time frame?
