    Python is not C and strings are objects not not simple pointers to some memory area. Commented Oct 7, 2013 at 9:34

  • @user2799617 i mentioned that i am coming from c background. did not have much idea about python. to be clear about memory allocation in case of sting, i asked this question. Commented Oct 7, 2013 at 9:37

There isn't one. Python strings store the length of the string independent from the string contents.

There is nothing like that in Python. A string is simply a string. The following:

test = "Hello, world!"

is simply a string of 13 characters. It's a self-contained object and it knows how many character it contains, there is no need for an end-of-string notation.

Python's string management is internally a little more complex than that. Strings is a sequence type so that from a python coder's point of view it is more an array of characters than anything. (And so it has no terminating character but just a length property.)

If you must know: Internally python strings' data character arrays are null terminated. But the String object stores a couple of other properties as well. (e.g. the hash of the string for use as key in dictionaries.)
