Working with timestamps from jpg.filename-CodePudding

I have a folder ("pictures") with many jpg.files with the filename as timestamp (e.g. "09_02_01.jp" or "10_04_01.jpg"). Now I want to iterate through the folder and all jpg files and use the filenames as timestamps. With these timestamps I want to check if some filenames (jpgs) are nearby. For e.g. if a timestamp of a picture is 09_02_01.jpg and another is 10_04_01.jpg I want to get the difference of the timestamps of the pictures and if the pictures difference is less than 30 seconds e.g. than I want to delete one of the pictures, because I only want one picture for every 30 seconds.

At the moment I only got the jpg filename convertet into a datetime format.

from datetime import datetime
import os

def gettime(folder_dir):
    timediff_sec = 30

    for images in os.listdir(folder_dir):
        if images.endswith(".jpg"):

            fn, fext = os.path.splitext(images)

            # string name
            timestamp1 = fn

            # Convert String to datetime Object
            t1 = datetime.strptime(timestamp1, "%H_%M_%S").time()

            print(t1)

gettime("Bilder")

CodePudding user response：

You can try my code below:

from datetime import datetime
import os

def gettime(folder_dir):
    timediff_sec = 30
    time_stamps = []
    for images in os.listdir(folder_dir):
        if images.endswith(".jpg"):
            fn, fext = os.path.splitext(images)

            # string name
            timestamp1 = fn

            # Convert String to datetime Object
            t1 = datetime.strptime(timestamp1, "%H_%M_%S")
            t1 = datetime.timestamp(t1)
            if len(time_stamps) == 0 or abs(int(t1) - min(time_stamps)) >= 30 or abs(int(t1) - max(time_stamps)) >= 30:
                time_stamps.append(int(t1))
            else:
                os.remove(os.path.join(folder_dir, images))

gettime("Bilder")
