Rename file name in python

Question

Im looking to rename a file which is always export(x).csv but the x can be a random number.

Id like to rename it with the date format YYYYMMDDHHMM.csv

import os

old_file = os.path.join("c:\", "export%")

new_file = os.path.join("c:\", "YYYYMMDDHHMM.csv")

os.rename(old_file, new_file)

Answer 1

If you want YYYYMMDDHHMM of the current day, you can use datetime:

s=datetime.today().strftime('%Y%m%d%H%M')

Note that:

• %Y = Year
• %m = month
• %d = day
• %H = hours
• %M = Minutes

You can also read this . So, in your code:

new_file = os.path.join("c:/", s+".csv")

Just for example:

from datetime import datetime

s=datetime.today().strftime('%Y%m%d%H%M')
print(s)

will produce:
