Hello,
I'm attempting to write a script that takes in a CSV file and utilizes an arcpy.TableToTable_conversion() to create a table in a geodatabase. I would like to take advantage of Field Mapping functionality in arcpy so that I can reliably/consistently create a table with the same attributes.
Based on some direction I've found on this forum, I've tried the following code. It creates a table but does not honor the length values of the various string fields (i.e. all string fields are length = 255):
