People,
I am trying to determine the creation date of files in a folder. I am using the following code to find the folder and confirm that files
exist in the folder.
Presumably you meant "intend to use the following pseudocode" (not "am using the following code") -- many of the statements (marked XXX below) are just not valid Python.
XXXIf someone could give me an idea how to check a creation date it would be appreciated. Thanks dave
def delete_old_files (t:\dm\~\users)
# find files and delete files created more than XX number of days
ago update_exist = 0
Did you mean "file_delete = 0"?
input_dir = t:\dm\~\users\xxxx.yyyyyy\zzzzXXX
if os.path.exists (input_dir) :Not necessary -- "for file in files" does nothing gracefully if files is empty. If it were necessary, "if not files:" is suggested as an alternative to "if len(files)".
files = os.listdir (input_dir)
else:
print "Unable to find input file dir: %s !!!" % input_dir
sys.exit(2)
if len(files):
for file in files :
file = os.path.join(input_dir) #all files in output
directory will be csv or xls, can be deleted if old enough
I think you mean "file = os.path.join(input_dir, file)"
if os.path.isfile(file): #need to check ext not file, fileXXX
name changes each day
if re.search(t:\dm\~\users\xxxxx\) and #creation date
You don't need the re module to check if the file's extension is "csv" or "xls"
gt x number of days ago t:\dm\~\users\davef.input_list.delete(file)XXX
file_delete = 1
if file_delete:
print "\n file deleted: \n%s" %
str(t:\dm\~\users\xxxxx.input_list)
return file_delete
Now, to answer your question: You have obviously read the docs on the os module; what did you not understand about os.stat()?
I suggest you contemplate the following real-not-pseudo-code and then examine the relevant sections of the docs for os.stat(), the stat module, and the time module.
C:\junk>type st_ctime.py import os, stat, time
def get_create_time(path):
int_time = os.stat(path)[stat.ST_CTIME]
str_time = time.ctime(int_time)
return str_timeif __name__ == "__main__":
import glob, sys
for arg in sys.argv[1:]:
for path in glob.glob(arg):
create_time = get_create_time(path)
print path, create_time
