@xtanion Thanks for your contribution!

Closing this PR because the "main" branch has been updated to have a different implementation of upload_file_to_dsn:

zowe-client-python-sdk/src/zos_files/zowe/zos_files_for_zowe_sdk/files.py

Lines 426 to 432 in d9af9c3

	def upload_file_to_dsn(self, input_file, dataset_name, encoding=_ZOWE_FILES_DEFAULT_ENCODING):
	"""Upload contents of a given file and uploads it to a dataset."""
	if os.path.isfile(input_file):
	with open(input_file, 'rb') as in_file:
	response_json = self.write_to_dsn(dataset_name, in_file)
	else:
	raise FileNotFound(input_file)

A new contribution to the "main" branch would be welcome 🙂
