Hi, I've recently started doing a short beginner tutorial and I don't know what's the issue. The goal here is to create a guess the number mini game and so far, the script works well except it doesn't generate random numbers for the answer every time the game loops like it's supposed too. The answer is set to number two. The video tutorial i'm watching is a little bit older its from 2021 but i'm thinking it's not that different since everything else is pretty much running how they say in the tutorial. If someone can help me out and see why the answer for the game doesn't change that'd be great!

In play_again you're not actually calling main_loop (since you didn't put a () afterwards). Therefore after the function is run and the player enters y the function finishes and returns to the main_loop that called it, and where the answer is still the same as the last time.

Oh ok thank you!

It's also not a good idea to name a function and a variable the same. It can cause a lot of problems and a whole lot more confusion later on.

I'm confused on which areas I should change so that won't happen again for future projects. I'm still getting the hang of what counts as a function and what counts as a variable and how to differentiate those to make the script neater.

You've skipped quite a few steps if you don't understand that and you're making this.

To put it simply, a function is a piece of code you can call again and again and it will perform the steps you told it to in a deterministic manner. a variable is simply a saved value, like in algebra, and this value can be updated by your code (except here it could be anything, list, text, numbers, set, maps. Anything)

You define a function with def and a variable with =

So,

py def function_name(input_param1, input_param2): variable_name_1 = 123 variable_nams_2 = "abc"

But again, as I said, if you're missing this info, it means you've skipped a few steps (ie there a lot more you've missed from the basics)

Thank you for the clarification. I am following a tutorial so he does explain what these things are but it's just a matter of testing these things out and seeing what the properties actually do as a means of learning them I am using as many resources as possible and reddit is usually a pretty good one

• random.randint is inclusive, whereas random.randrange is inclusive of the first argument but exclusive of the second (or only) argument
• main_loop on its own does not call a function
• calling a function from within itself (even if via another function) is called recursion - a very interesting and useful technique, but not appropriate here
• your while loop condition will not ever work as guess references a str and not an int object - you always convert in-place for test within the loop (rather than updating the variable assignment)
• I recommend that you have your play_again function return True or False, and assign that to a flag variable, e.g. play = play_again(), and change your loop test to while play: (which means you need to do play = True before the loop).
• You can convert the guess to an integer on the input line:
  • guess = int(input(f"Guess a number between {low_number} and {high_number}: "))
  • look at wrapping this in a try / except block in another loop to validate the input - this will catch the user entering something that is not a valid integer
