• [nitpick] Consider adding a clear separator or rephrasing the error message to improve readability, for example inserting a colon or space between the check_string and the output.

print('::error:: can not find string ' + check_string + output)

• There is a spelling mistake in the variable name 'config_bacakup'. It should be renamed to 'config_backup' for clarity.

config_bacakup = config_file+'.origin'
