How to Change image captured date in python?

Question

I have over 500 images (png /jpg) having wrong captured date (Date taken) because of wrong camera date settings. I moved photos to mobile and mobile gallery sorts photos on the

Answer 1

PNG does not support EXIF so I made this to fix the creation/modification time instead, based on Wilbur Dsouza's answer:

import datetime
import os
import re
import sys
import time

import piexif


def fix(directory):
    print(directory)
    for dirpath, _, filenames in os.walk(directory):
        for f in filenames:
            fullPath = os.path.abspath(os.path.join(dirpath, f))
            # Format: Screenshot_20170204-200801.png
            if re.match(r"^Screenshot_\d\d\d\d\d\d\d\d-\d\d\d\d\d\d.*", f):
                match = re.search("^Screenshot_(\d\d\d\d)(\d\d)(\d\d)-(\d\d)(\d\d)(\d\d).*", f)
                year = int(match.group(1))
                month = int(match.group(2))
                day = int(match.group(3))
                hour = int(match.group(4))
                minute = int(match.group(5))
                second = int(match.group(6))

                date = datetime.datetime(year=year, month=month, day=day, hour=hour, minute=minute, second=second)
                modTime = time.mktime(date.timetuple())

                print(f, date)

                os.utime(fullPath, (modTime, modTime))


if __name__ == "__main__":
    fix(sys.argv[1])
