I copy this script from the magpi but when I run this script I get this error:

Below is the eamplescript. What is wrong with this script.

Watch your quotes. They want to be flat quotes, U+0022 "this sort",
not any sort of typographical quote.
Recommendation: Use a programmer's editor, not a word processor, for
working with code. As well as not mangling it, it'll often show you
problems before they happen.
Also, recommendation: Use Python 3, not Python 2. Your code looks like
it's intended for Py3, but your error says that you ran it under Py2.
The solution may be as simple as running "python3 script.py" rather
than "python script.py".

If the caret ^ would line up with the invalid character, that would give a

hint to the reader which character was invalid. Or perhaps showing, or
naming, the invalid character in the error message:

you the line, you have to go look for it yourself. Then you have to work
out what character is \xe2, which is generally not easy because your editor
is unlikely to show the escape code but rather some apparently normal
looking character.

“Cheer up,” they said, “things could be worse.” So I cheered up, and sure

You shouldn't need to set your python path. But, what you may need to

do is install pyaudio under Python 3. Whatever you did for Py2, do
again for Py3 - for instance:
$ sudo python3 -m pip install pyaudio

No, but you do have to install pyaudio separately for each version of Python

you have.
So if you have installed Python 2.7 and 3.4, and Python 2.7 has pyaudio
installed, Python 3.4 cannot use the same one.

Try using input=True instead.

You need to install the Pytyon3 version of pyaudio...

I don't think we can solve those errors
Anyway thanks for helping me out so far.
