[Tutor] How to generate a pure tones and random noise using Python?

[Paul Z]

Hi Laura,

I just have read this webpage about Generate Audio with Python. 
It seem writing by Python 2? Esp. itertools (izip, imap).
I try to change izip and imap to zip and map, but I get error:

beatfreq, amplitude = remainder.split('/')
ValueError: need more than 1 value to unpack

Are there some way to conver it to the code of Python 3?

I'm too anxious to hear the sound from Python though I'm a absolute beginner.

Many thanks

Paul Z
