EN

isdone = ""
while isdone != "done":
    try:
        route = "container"
        userinput = input("what extensions would you like to search for?\n seperate each denotion with a space \n ex: div div img[\"title\"]\n: ")
        inputRoute = userinput.split(' ')
        for i in range(len(inputRoute)):
            route += "." + inputRoute[i]        
        print("---\n"+route+"\n---")
        print("Current Route ^\n---")
        print("output:\n", exec(route),"\n---")#actual resaults if user had inputed a
        print(container.a) # what i actually want to output (if the user only inputed a) 
        #add the abilitie to add extensions ex: container.div.a.img["foo"] -ignore this stackoverflow
        isdone = input("are you happy with these extensions? \n type 'done' when happy\n or enter to change extension\n: ") 
    except Exception as e:
        print(e)
        input("Make sure their is no leftover spaces\npress enter to continue")

'what extensions would you like to search for?
 seperate each denotion with a space
 ex: div div img["title"]
: a                 #  <--what I put in the input
---
container.a #what  
---
Current Route ^
---
output:              
 None               #  <-- what actually outputs when i use exec()
