How can i make sound with frequency in python3?

Question

I tried this, but it didn't made more than an empty line :

import os
a=300
b=2000
os.system('play --no-show-progress --null --channels 1 synth %s sine %f' % ( a, b))

Change the `os.system` to `print`, then run the code and copy and paste the string to your terminal. Does this then play the sound you want? — Stephen Rauch, May 10 '17 at 23:34
The run still gives an empty line. In the terminal the string just prints it. — Turcsi, May 11 '17 at 07:16

Easy ways to play a beep sound of given frequency and duration in Python:

frequency = 1000 # Hertz
duration  = 2000 # milliseconds

On Windows:

import winsound
winsound.Beep(frequency, duration)

On Linux:

# SoX must be installed using 'sudo apt-get install sox' in the terminal
import os
os.system('play -n synth %s sin %s' % (duration/1000, frequency))

On macOS:

# First install Homebrew (https://brew.sh/) 
# and then SoX using 'brew install sox' in the terminal
import os
os.system('play -n synth %s sin %s' % (duration/1000, frequency))

Cross-platform:

Using PyAudio module and a bit of coding: https://stackoverflow.com/a/27978895

play WARN sox: Option `-f' is deprecated, use `-e floating-point' instead. play WARN getopt: option `l' not recognized play: SoX v14.4.1 play FAIL sox: invalid option – Turcsi May 11 '17 at 20:09
On which platform are you, and which solution did you try? – Josselin May 11 '17 at 20:56
On Ubuntu with the second solution. – Turcsi May 12 '17 at 07:49
I updated my answer with a more general Linux solution. Now it should work (I tested it on Ubuntu 16.04.2 LTS) – Josselin May 12 '17 at 14:40
