What is the difference between docstring and an ordinary string?

Question

I am new to this python and I am getting it.

Answer 1

You can get a docstring from outside where it is defined, using the help function.

def f() :
"Your doc string"
# function code here

help(f)

output: That docstring of yours.

So type-wise a docstring is just an ordinary string; but if you put it in the right place (beginning of a function, class or module), Python enables you to use this string for informing the user of that code. That's what makes it a 'doc string'.
