I have the following code that I developed to convert my `.dbf` zonal statistics outputs into `.xls` using arcpy. I am trying to run the loop using three files as a test; 
`ppt_07223000_190001.dbf`, `ppt_07223000_190002.dbf` and `ppt_07223000_190001.dbf`

```
import arcpy
import os
import glob
from arcpy.sa import *
from arcpy import env
import numpy as np

####################
# Set the workspace#
####################

arcpy.env.overwriteOutput=True
arcpy.env.workspace = r'D:\Prism\tdmean files\tdmean_Excel'

############################
### Search for dbf files ###
############################

dbf_filenames = sorted(glob.glob("*.dbf"))

# pieces = 10
# new_arrays = np.array_split(dbf_filenames, pieces)

for dbf in dbf_filenames:
    # print(dbf)
    basefilename = os.path.basename(dbf)
    # print(basefilename)
    CleanBaseStr = os.path.splitext(basefilename)[0]
    field_name = "Year_Month"
    field_type = "DOUBLE"

    # arcpy.management.DeleteField(dbf, field_name)
    arcpy.management.AddField(dbf, field_name, field_type, field_length = 6)

    field = ["Year_Month"]
    yearmonth = os.path.splitext(basefilename)[0][13:21]

    with arcpy.da.UpdateCursor(dbf, field) as cursor:
            try:
                for row in cursor:

                    row[0] = yearmonth
                    cursor.updateRow(row)

                    ### Execute table to excel
                    out_xls = CleanBaseStr + ".xls"
                    print(f"{out_xls} : {row}")
                    arcpy.TableToExcel_conversion(dbf, out_xls)
            except:
                continue
```


Ideally the output should look something like this. 
[![Excel Output][1]][1]

However, the issue arises in the directory. For some reason, the loop gets stuck after the first run and gets locked there.
```
# ppt_07223000_190001.xls : ['190001']
```
 There is no error produced which makes it a bit more confusing.

However, when changing the `arcpy.env.workspace` to an external workspace, the script runs as shown by this print statement, but no excel output is produced.

```
# ppt_07223000_190001.xls : ['190001']
# ppt_07223000_190002.xls : ['190002']
# ppt_07223000_190003.xls : ['190003']
