If I have a string of variable length and I want to return only first 3 characters of the string.

str[:3]

this works but I want to know if the string is of lesser length, suppose 2, "ab" or just "a", will this slicing work for that too? Thanks in advance

    Welcome to Stack overflow! You know, you can always fire up a python command line and test it for yourself... – ori6151 Oct 19 '19 at 22:16

    See the documentation and existing references for such trivial questions: “python slice string” or “python slice documentation” on google return relevant results.

Python will return at most :n characters: 'a'[:3] will simply return 'a'. ''[:3] returns ''.

You could have tested for yourself in less time than it would have taken to open your browser.

But yes.
