Ok, so I was making a simple python program that mimics simple evolutionary processes. When I run it multiple times I keep getting different results and I have no idea what is happening. Please help.

Like we can read in Python documentation:

https://docs.python.org/3/library/random.html

random.seed( value ) initializes random number generator. But if it's not present in code, current time is used, but time is changing all the time.. Different seed, different results from random.randInt()..

So, if you want to have each time the same results, use random.seed( 0 ); at the beginning of script.

It's reverse from C/C++ implementation of random number generator, in which you must execute srand( time() ); manually if you don't want to have exactly the same results.

Yep, you right. I get the same results each time now. Thank's Senpai.
