How to use Python placeholders in a web browser string

Question

I need to format a string and send it to a web browser with the splinter module. I usually use placeholder, but this time it doesn't work. This is the string I want to pass to the browser:

http://NAMESERVER:8082/ViewObjectRes//TransactionLogManagerPostErrorHandling\%28Instance+0\%29\%3Ainstance\%3DInstance+0

where NAMESERVER is the fqdn of the server which I want to connect to. I tried use the placeholder as usual but I get an error:

print ("http://%s:8082/ViewObjectRes//TransactionLogManagerPostErrorHandling\\%28Instance+0\\%29\\%3Ainstance\\%3DInstance+0" % "TEST")

TypeError: not enough arguments for format string

I guess should escape all the other percentage sign, but I tried without success.

After your confirmation, I was able to search better and find the solution. I used double percentage sign %%. thank you very much! — Lornioiz

possibly easier, with a url that might contain %, to use format?

print "http://{}:8082/ViewObjectRes//TransactionLogManagerPostErrorHandling\\%28Instance+0\\%29\\%3Ainstance\\%3DInstance+0".format("TEST")

I had complitely neglected to study the format function... it looks more elegant than placeholder for my purpose. Thank you.
