#94919 — Re: I'm a newbie and I'm still stumped...

Thank you, Emile, Paul, Terry, and Joel for your suggestions! And the
error persists.

Maybe my error is coming from running the old version (2.7.6) of Python,
but I can’t figure out why that would be happening???

I downloaded 3.4.3 again from the Python.org website for my Mac.
I inserted the "import sys" and did “print (sys.version)” into the code.

So here what the code is:

#!/usr/bin/env python3
import sys
print (sys.version)
word = input('Enter a word ')


Here are the results I got below, showing the same error. The first line
says, 
"2.7.6 (default, Sep 9 2014, 15:04:36)”. Does that mean I am running the
old Python? How could that be since I am SURE I downloaded 3.4.3 (it even
gives the folder name as “Python 3.4” in the Applications folder on my Mac.

2.7.6 (default, Sep  9 2014, 15:04:36)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)]
Enter a word serendipity
Traceback (most recent call last):
  File "test short.py", line 4, in <module>
    word = input('Enter a word ')
  File "<string>", line 1, in <module>
NameError: name 'serendipity' is not defined




Please help…

BIG SMILE...

Always, Dwight

Use raw_input instead of input.  In python 2.x, input treats the stuff
you enter as a Python expression instead of a string.

Yes, that's Python2.  I've never used MAC OS, but I understand that it
has the BASH shell, so you can use "which" try to figure out where
python is being found on the path:

$ echo $PATH

$ which python

Use the above to also check for the position of python2 and python3.

You can check for aliases and links with the "type" and "file" commands.
Do this for python, python2 and python3:

$ type $(which python)

$ file $(which python)

How are you launching your script? If your method involves clicking some
pretty picture or something similar, you may be bypassing /usr/bin/env
altogether and relying on some association of file types in Mac OS. Then
you need to investigate file properties in Finder, or something like
that. It should be safe to change the association for that individual
script but not necessarily for all files with the same extension.

If your method is to type "python scriptname" at the shell prompt, you
are definitely bypassing /usr/bin/env and specifying the default python
as the one to use. Solution: type "python3 scriptname" instead. (A more
advanced solution: make scriptname executable and type "./scriptname"
instead. This one uses /usr/bin/env to find the interpreter.)

(You could try "#!/usr/bin/env aintgotnosuch" as your script's hashbang
line to see if it even matters what that line says. Check first that you
don't happen to have a program named "aintgotnosuch" in your path.)
