I try to draw a real-time map based on one field. And I will update this field with another kept-on-generating dataframe. I forgo to finish it with updateCursor because it is so slow. Instead, I try to convert dbf into a csv file and merge it with that dataframe then convert it back to the dbf file.

It works well in 1st time. But since I have used the function TableToTable_conversion to generate a dbf file, it will add a table under that map in arcgis pro. Therefore I have to delete that table first before I run ableToTable_conversion to generate a generated dbf file. So what is the corresponding code in arcpy to delete that table?

BTW: I can visit these tables using this code:

tbs = mp.listTables()

for tb in tb:

   print(tb.name)

The tool you want to use is Delete (Data Management)—ArcGIS Pro | Documentation.  Although you can set the workspace and then just rely on names, be aware that if you have a table view and table with the exact same name, the table view will be deleted first and only leaving the table still on disk but not loaded in map.  Passing the full path of the table ensures the table will be deleted and table view removed from map.

Thank you for your reply! I have known how to delete the table and substitute it with a new .dbf file. Now the problem is that I tried to use a for loop to keep updating the map displayed in the interface based on the newest updated data in each loop. But it seems that the map will update only once after the whole for loop is finished. I don't know why. Because in the arcgis Map, I can use refresh function to refresh it.

Without seeing more of your code, specifically the loop part, I can't really comment any further.

I think I have solved this problem in another way with the function you provided under my other question!

Although the interface didn't update with the data, the exported Pictures has already been updated with mp.defaultView.exportToPNG.

Thank you! You saved my ass.
