We play a game where each of us secretly draws a random number uniformly between 0 and 1. Each player can choose to keep this value or discard it and draw a new number, also uniformly random between 0 and 1, without observing the other player’s number or decision. The player with the higher final number wins $100. What strategy would you use?

Asked to download a Pandas dataframe containing hourly weather data from 3 weather stations spanning a year. Had to do some manipulation of the dataframe to find specific information such as first temperature reading of each day for each station. Then had to find first, last, minimum and maximum readings of each day for each station without using pandas builtin functions, with a single pass by iterating on rows.
