Add date to feature class name?

Question

I still working on my big project, big at least for me, but I am currently stuck on this:

I have a lots of .shp, that I want to move to a gdb. While creating a feature class, I want to add date (YMD) before the name: test.shp -> _120706_test

Possibly the creation date of the SHP but also the importing date will be ok.

I created a list of feature and tried: _fc = '' + fc BUT AIN'T WORKING!

THANKS A LOT

Answer 1

The first thing that jumps out is: the rename command should be:

arcpy.Rename_management(in_data, out_data, data_type)

This may help to find the created date: How to get file creation & modification date/times in Python?

You'll probably want to read up on the os.path and datetime modules and string formatting in Python (new or old styles).

Here is a small example to hopefully get you going:

import os, datetime

fc = r"C:\GISData\atlantic_hurricanes_2000.shp"
ctime = datetime.datetime.fromtimestamp(os.path.getctime(fc))
ymd = ctime.strftime("%Y%m%d")
inputFcName = os.path.splitext(os.path.basename(fc))[0]
outputFcName = "%s_%s" % (ymd, inputFcName)

print outputFcName # prints 20120315_atlantic_hurricanes_2000

I always do something like:

from time import strftime
outFile = "myfeatureClassName" + "_" + strftime("%d%b%y")

and then just use the 'outFile' variable for your output parameter on whichever geoprocessing tool you are using. The syntax inside brackets of the strftime function can changes the date format. Here's a decent look at the different types:
