writing to to Exif header using the execute() method

[snowman907]

My goal is to write data into the Exif-header of an image.
Looking over a post from 2015 link on how to use Exiftool to write to the Exif header. I gave it a try:

import exiftool
fileno=r'DSC00001.JPG
with exiftool.ExifTool() as et:
    et.execute("EXIF:GPSLongitude=100",fileno)
    et.execute("EXIF:GPSLatitude=100",fileno)

In response, I got the following error:

TypeError: sequence item 0: expected a bytes-like object, str found

Then as specified in the documentation, execute takes byte commands, so I bites, so I tried that too:

with exiftool.ExifTool() as et:
   et.execute(bytes("EXIF:GPSLongitude=100", 'utf-8'),fileno)
   et.execute(bytes("EXIF:GPSLatitude=50",'utf-8'),fileno)

But still got the same error :

TypeError: sequence item 1: expected a bytes-like object, str found

I am not sure what am I doing wrong, and if Exiftool can write to file.
Thanks for the help. This question was also posted on StackOverflow here

Hi, you should change like the following

import exiftool

fileno=r'DSC00001.JPG
with exiftool.ExifTool() as et:
    et.execute("-GPSLongitude=100",fileno)
    et.execute("-GPSLatitude=100",fileno)

This works well for me
