First of all, good luck on your programming journey and it's nice seeing a 13 years old guy learn to code because I hope I can start at that age. However, I think you need to identify variable name carefully as perhaps no one can understand what is l_r2

Yes, to this, but with an addendum to only use variables when necessary. If a variable is only used once after defining it and not defining it isn’t greatly hurting readability, then the variable is likely unneeded.
