Hello dear stackexchange Community :) I've been learning Python for about 4 days now. Python is my first programming language, accordingly im not that good at coding yet. I have been programming a little random number game as my first project and came to a state of code with which im kind of happy. My code does what i want, it generates a random number between 1 and 20, prints the initial tip and asks the user of an input guess. Should i guess right it completes the round, adds 100 points to my score and continues with round 2. When i did not guess correct, it substracts 20 points off my score and asks me to try again for another 2 attempts until i lose. Now my question would be, in which way i can improve my code. What i mean by this are the weaknesses of this code and what could be ways to write that code more efficient/generally better/more clear whatsoever. So in general im asking for little tips to shape(or reshape if its a complete failure)my code. I hope this question isnt too shallow im still very new in this forum and i excuse myself for eventual grammar mistakes, english is not my first language. Hope you have a nice day :) Greetings, Marc
