python - changing date modified folder output-CodePudding

I have this python code which outputs the directory last modified date output.

import os
import time

print (time.ctime(max(os.stat(root).st_mtime for root,_,_ in os.walk('/Users/<username>/Desktop/newFolder'))))

output

Sun Jan  9 12:17:01 2022

Question: is there a way to change the output format with a parameter or you would have to built out a converter? To get just the year, month and day? Not to familiar with python code which I found.

desired result

2022-1-9 or 2022-01-9 or YYYY MM DD

Take a look at the following topic

ctime is not good for the desired action as it returns str

Python Format Ctime Method

CodePudding user response：

Using the datetime module, first convert the timestamp to a datetime.datetime object using the fromtimestamp method, and then use the strftime method to format the time string.

import os
from datetime import datetime


def convert(timestamp) -> str:
    return datetime.fromtimestamp(timestamp).strftime("%Y-%m-%d")


print(convert(max(os.stat(root).st_mtime for root,_,_ in os.walk('/Users/<username>/Desktop/newFolder'))))

# YYYY-MM-DD

Look for

https://github.com/srccircumflex/scripts.py

for a somewhat portable form of os.scandir

                'st_mtime': 1642249147,
