Hi,
The following lines of code gives an error starting with
line where len() is used
local_BkFiles = glob.glob(localDirectoryName+'\\*' +
data + '*bk*')
local_BkFiles.sort(key=str.upper)
last_pv_File_Name = local_PvFiles[len(local_PvFiles)-1]
split_last_pv_File_Name =
re.search(data+"_bk[0-9]{2}_[a-z]{3}_pv[0-9]{2}",last_pv_File_Name )
lastPv_FileVersion =
re.search('(?<=pv)\d+',split_last_pv_File_Name.group(0))
This code is being called in a procedure or function def. How may I
solve this.

Since you didn't post your full traceback (you should always do that in
the
future), we are guessing:
local_PvFiles isn't defined prior to trying to determine its length.
The way to get the last element of a list is:
local_PvFiles[-1]
you don't need to do all the length gymnastics.
I'm no regex expert, so I'll leave that part to someone else but if the
filenames are a fixed format, you don't need regex at all to extract the
version. If it is a completely variable format, then you would.

What "this" to you want to solve? I see no traceback, no listing of files, no
explanation of what you are trying to do. Help us try to help you.
Taking a second look, You sort local_BkFiles:
local_BkFiles.sort(key=str.upper)
Then you access local_PvFiles:
last_pv_File_Name = local_PvFiles[len(local_PvFiles)-1]
did you mean local_BkFiles?
(a full traceback would have pointed that out immediately)
