If you are searching for an answer of “what does %s mean in python” Kindly be informed that the % is a string formatting syntax in Python. Here is a very simple example:
#Python2
name = raw_input("who are you? ")
print "hello %s" % (name,)
#Python3+
name = input("who are you? ")
print("hello %s" % (name,))
The %s token will help you to insert a string. Notice that the %s token is substituted by whatever values you pass to the string after the % symbol.
