First, get the file list.

It seems to use glob. http://www.yukun.info/blog/2008/08/python-directory-listdir-glob.html Thank you for the information.

combine_TFRecords_170722.py

import glob

"""
v0.1 Jul. 22, 2017
    - get file list
"""

# codingrule:PEP8

res = glob.glob("../run*/IntField-Y_170709.tfrecords")
for elem in res:
    print(elem)

Sort by modification time

(Addition 2017/10/03)

Reference: https://stackoverflow.com/questions/6773584/how-is-pythons-glob-glob-ordered

The order in glob.glob () execution will be the same as ls -U.

Use sort () to sort by modification time.

import os
sorted(glob.glob('*.png'), key=os.path.getmtime)
