[PYTHON] Matching karaoke keys ~ I tried to put it on Laravel ~ <on the way>

Last time I wrote a program to match karaoke keys with python. This time, I made a page that can call this program from Laravel while learning.

However, since I just wrote PHP, I can hardly use the function of Laravel ^ ^;

What i did

--Called python from PHP on the command line and got the output --The range of your own and the range of the song you want to sing are acquired with the select box and sent with get.

Source code

As a memorandum for myself.

--Get $ origkey (the highest note of your own) and $ adkey (the highest note of the song you want to sing) --ʻExeccalls python locally --The output result is stored in$ outpara --The select box can be set to the initial value by addingselected to the tag. --The python program is placed under publicto make the call simple --In the case of laravel, the home directory (I don't know if it's correct) ispublic. --The output of the python program was narrowed down to only the following two --type: Information such as one octave up, one octave down, and the original song mama --diff_key`: How much key should I adjust?

result

This is the initial page.

Play around with the select box and press the'Adjust' button. If you look at the URL of the updated page, you can see that the parameters have been sent by GET.

Improvement points

――The select box is awkward, so I want to use bootstrap or something. --The code is too dirty, so refactor it --It's too clumsy to realize side by side with the table tag, so fix it --Allows you to search for range information by song title or artist ――Borrow VPS etc. and make it publicly available
