Writing exif data to the exif header using PyExifTool - python-3.x

Question

Looking over a post from 2015 link on how to use PyExifTool 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.

Answer 1

The problem is that the execute method is low-level and requires bytes as inputs for both the parameters you pass and the file name. Try this:
import exiftool
pic = b"DSC00001.JPG"
with exiftool.ExifTool() as et:
et.execute(b"-GPSLatitude=11.1", pic)
tag = et.get_tag("EXIF:GPSLatitude", pic)
print(tag)

#Gracias!
exif = r'...\exiftool.exe'
file=br"...\FRM_20220111_134802.JPG"
with exiftool.ExifTool(exif) as et:
et.execute(b"-DateTimeOriginal=2022:10:10 10:10:10", file)
tag = et.get_tag("EXIF:DateTimeOriginal", file)
