Hello guys. I hope you can help me with the following issue:
I am working with python, MySQL and multithreading, and really newbie in all of this; however, I am trying to do multiple sql queries at 3 threadings I have. That threads consist in general loop that is reading a specific table from database.
I am using just one database. I use mysql.connector provided by MySQL for Windows. Here is my code:
As you can see, I have 3 functions that have a loop (newWh, readWh and sentWh = these are the three functions, their loops are infinite). But, when I execute it, I obtain the following error:
(I can't post the image url)
I don't know if there are problem with MySQL, I was searching about initialize more MySQL instances but I don't find anything that show how to do this in Windows.
So, I don't know, I believe too that is a problem with MySQL ports. I don't know what is the problem, for this reason, I hope that you can help me guys.
If you see multiple source code errors, notify me, I am a new programmer on python and newbie (x1000) working with multi-threading, so, if there are ways the optimize that source code with inheritance or oop programming, notify me, I want to learn python at pro level. Thank you for help.

I don't know if there are problem with MySQL, I was searching about initialize more MySQL instances but I don't find anything that show how to do this in Windows.
So, I don't know, I believe too that is a problem with MySQL ports. I don't know what is the problem, for this reason, I hope that you can help me guys.
If you see multiple source code errors, notify me, I am a new programmer on python and newbie (x1000) working with multi-threading, so, if there are ways the optimize that source code with inheritance or oop programming, notify me, I want to learn python at pro level. Thank you for help.
