myHex | 基于 cocos creator V 1.9.2 六边形消除游戏开发教程，线上试玩地址： | Game Engine library

In PostgreSQL, let's say I have the following table:

I am able to generate random hex values in a specific range using the code below, but I get the same random value on each line if i set my counter to more than 1. I'm guessing I need a loop, I have tried with "for x in range" but my implementation must be wrong as it overflows. I'm new to python and have searched for days but can't seem to find how to implement it correctly.

I have researched this and while I could find some methods to convert a string consisting of a 3-digit integer to a string consisting of its 2-digit hex equivalent, I did not find a way to convert the 2-digit-hex string back into the original 3-digit integer.

For example, I would like to convert "015" to its 2-digit hex equivalent "0F" and vice versa.

Another example: "123" to "7B" and "7B" to "123".

I would prefer separate methods for these two conversions, rather than 1 function that can take either type of string and return the other.
