Hi,
I read the tutorial on "Why is join() a string method instead of a list
or tuple method?"
at link:
https://docs.python.org/2/faq/design.html#why-must-self-be-used-explicitly-in-method-definitions-and-calls
I have a problem on running the last line:
---------------
If none of these arguments persuade you, then for the moment you can
continue to use the join() function from the string module, which
allows
you to write
string.join(['1', '2', '4', '8', '16'], ", ")
-----------------------
My Python console is 2.7. It should be no problem because I see the
tutorial
is 2.7 too.
The console has these display:
string.join(['1', '2', '4', '8', '16'], ", ")
---------------------------------------------------------------------------
NameError Traceback (most recent call

----> 1 string.join(['1', '2', '4', '8', '16'], ", ")
NameError: name 'string' is not defined
From the context, I don't see string should be replaced by something
else.
Could you tell me why I have such an error?
You are trying to use the *string* module without importing it, I'd guess.
Try:
import string
first then you should be able to access string.join without error.
Now *I* am confused.
Shouldn't it be
", ".join(['1', '2', '4', '8', '16'])
instead? Without any importing?
