Jul 31, 2009 · The answer is "You can't" (assuming the OP meant unique IDs given some number N of such generated IDs). Any IDs generated using random processes have a probability (however low) of collision; that is, after all, the "random" part of the process.

I am making a set in Python to house all the symbols on my keyboard, but obviously a few pose some issues. Is there a way to get them all in there without encountering problems? Here is my set: symbols = {`,~,!,@,#,$,%,^,&,*,(,),_,-,+,=,{,[,},},|,\,:,;,",',<,,,>,.,?,/}

Each character in Unicode has a unique code. For example: The letter A has the code U+0041. The character ñ has the code U+00F1. The emoji has the code U+1F600. In Python, all text strings (str) are stored in Unicode format by default. This means you can work with any character, symbol, or emoji without worrying about text encoding.
