How to set tEXtComment inside PNG file using PYTHON PIL?

Question

Python

In the PNG, GIF, TIFF, JPG and some other file formats, it is possible to add text labels inside the file.


In the libraries PIL and PILLOW for Python, functions for working with such labels were not found. There are functions for reading EXIF ​​tags (PIL.ExifTags.TAGS) and info (PIL.image.info). The latter seems to be exactly what you need. But you do not need to read info, but write it down. Has anyone faced such a task?
