Similar to the Simon electronic toy, this memorization game uses the third-party playsound module to play four different sounds, which correspond to the A, S, D, and F keys on the keyboard. As you successfully repeat the pattern the game gives you, the patterns get longer and longer. How many sounds can you hold in your short-term memory?
If you look at the code, you’ll see that the playsound.playsound() function is passed the filename of the sound to play. You can download the sound files from these URLs:
https://inventwithpython.com/soundA.wav
https://inventwithpython.com/soundS.wav
https://inventwithpython.com/soundD.wav
https://inventwithpython.com/soundF.wav
Place these files in the same folder as soundmimic.py before running the program. More information about the playsound module can be found at https://pypi.org/project/playsound/. Users on macOS must also install the pyobjc module from https://pypi.org/project/pyobjc/ for playsound to work.
When you run soundmimic.py, the output will look like this:
Sound Mimic, by Al Sweigart [email protected]
Try to memorize a pattern of A S D F letters (each with its own sound)
as it gets longer and longer.
Press Enter to begin...
<screen clears>
Pattern: S
<screen clears>
Enter the pattern:
> s
Correct!
<screen clears>
Pattern: S F
<screen clears>
Enter the pattern:
> sf
Correct!
<screen clears>
Pattern: S F F
<screen clears>
Enter the pattern:
> sff
Correct!
<screen clears>
Pattern: S F F D
--snip--This program imports the playsound module, which can play sound files. The module has one function, playsound(), to which you can pass the filename of a .wav or .mp3 file to play. On each round of the game, the program appends a randomly chosen letter (either A, S, D, or F) to the pattern list and plays the sounds in this list. As the pattern list grows longer, so does the pattern of sound files the player must memorize.
