I have a long list of events that are in a pandas dataframe with the event start and end dates for each event. How can I find the "nearest" event in each city & venue combination using pandas.groupby()?

Nearest event could be an event in the past, if no new upcoming events. i.e latest event in the dataframe in this case, which happened to be in the past. If there are multiple upcoming events, the one closest in the future will be considered as nearest event.

I tried groupby.agg("max") as below but that will give the event that is farthest in the future always:

I have the following code which group the users with same age and highest score among them. I have now instead of Map> one object called Person and in the person class there Map Map nameScoreTogether;.

I am trying to split a string using shlex but I want to preserve(literally) "\t", "\n", "\r".

Example:

I am using the Yelp API to return a list of businesses, the response is an object that has a key called "businesses" the value for this key is an array of 20 items those items are objects, but I am not sure how to access each item in the array without hard coding it like array[0] I would like to use a variable to access the index of the array dynamically so I won't have to input 0,1 etc and I'd be able to input the index needed to get the id or location for every item within this array here's an example business[vartoaccesseachindex].id. The reason for this is because I am using a .map() function to return a new array of objects with the values I need from the response.

Here is the object from the response

So I have a JSON url with some data like name, latitude and longitude. However, not every object has a latitude and longitude and I only want to display the names of the objects that do have the latitude and longitude.

JSON example object with lat and lng:
