Doubts about expressions

Ignition
1

Good night. I’m new to ignition and have had some doubts about ignition project programming at the company I work for. I would like someone to give me just some idea of ​​the line of code that I will share below.

if Execute == 1:
		myNameLow = system.tag.read("[.]zMyNameLow")
		myMachineNameLow = system.tag.read("[.]../zMyNameLow")
		historyPath = "machines_dm/%s/%s" % (myMachineNameLow.value,myNameLow.value)

My question is about this line:
machines_dm/%s/%s" %
I know that machines_DM is a folder that contains all the tags of plant machines. but an expression /% s /% s% could not understand.

SecondValue = currentValue.value

	Execute = 0
	if SecondValue == 0: Execute = 0
	if SecondValue == 10: Execute = 0
	if SecondValue == 20: Execute = 0
	if SecondValue == 30: Execute = 0
	if SecondValue == 40: Execute = 1
	if SecondValue == 50: Execute = 0
	if initialChange == 1: Execute = 0
	
	if Execute == 1:
		myname = system.tag.read("[.]zMyName")
		logger = system.util.getLogger(myname.value)
		#get my rated speeds from parameter data.
		Path = system.tag.read("[.]zMyRatedSpeedLookupPath")
		Path2 = "[~]%s" % (Path.value)
		Dataset = system.tag.read(Path2)
		#write dataset into our own tag
		system.tag.write("[.]zRatedSpeeds",Dataset)

and the second doubt is in the expression:
Path2 = “[~]%s” % (Path.value)

I didn’t understand what that row.

thanks!!!

This is just Python string formatting syntax.
