Editing/updating the data of photo metadata using pyexiftool

Question

I would like to update the data of photo metadata using exiftool, like data of temperature sensor, height sensor and GPS longitude-altitude. First, I\'ve tried to add new tags o

The code for your specific problem is:

import exiftool
et = exiftool.ExifTool("C:\Users\...\exiftool.exe")
et.execute("-GPSLongitude=10.0", "picture.jpg")
et.execute("-GPSLatitude=5.78", "picture.jpg")
et.execute("-GPSAltitude=100", "picture.jpg")
et.terminate()

Alternatively, you can leave out the terminate call when using the with statement:

with exiftool.ExifTool("C:\Users\...\exiftool.exe") as et:
    et.execute("-GPSLongitude=10.0", "picture.jpg")
    et.execute("-GPSLatitude=5.78", "picture.jpg")
    et.execute("-GPSAltitude=100", "picture.jpg")

Using the with statement makes sure that the subprocess is killed, see the PyExifTool documentation

If you want to change a date (create, modify, etc.), make sure to leave out the inverted commas around the date itself. That was what took me a while to figure out since no error handling takes place:

Command-line:

exiftool -FileModifyDate="2015:10:01 10:00:00" picture.jpg

Python:

et.execute("-FileModifyDate=2015:10:01 10:00:00", "picture.jpg")
