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.

Did you mean "file_delete = 0"?

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)".

I think you mean "file = os.path.join(input_dir, file)"

You don't need the re module to check if the file's extension is "csv"
or "xls"

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_time
if __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
