Python Python Basics (Retired) Pick a Number! Any Number! The Solution

OH! My GOD! Kenneths code is far more superior then mine. please compare them both and give me feedback.

mine:

import random

random = random.randint(1, 10)  


while True:
  print("Guess the right number between 1 and 10")
  ask = input("> ")
  user_num = int(ask)
  List = []
  ask.append(List)
  if user_num == random:
    print("Congrats! you have gussed the right number")
    break
  elif user_num > random:
    print("Too high")
    continue
  elif user_num < random:
    print("Too low")
    continue

print("It took you {} tryes to guess the number".format(len(List)))

Kenneth:

import random

rand_num = random.randint(1, 10)
guessed_nums = []
allowed_guesses = 5

while len(guessed_nums) < allowed_guesses:
  guess = input("Guess a number between 1 and 10: ")

  try:
    player_num = int(guess)
  except:
    print("That's not a whole number!")
    break

  if not player_num > 0 or not player_num < 11:
    print("That number isn't between 1 and 10!")
    break

  guessed_nums.append(player_num)

  if player_num == rand_num:
    print("You win! My number was {}.".format(rand_num))
    print("It took you {} tries.".format(len(guessed_nums)))
    break
  else:
    if rand_num > player_num:
      print("Nope! My number is higher than {}. Guess #{}".format(
        player_num, len(guessed_nums)))
    else:
      print("Nope! My number is lower than {}. Guess #{}".format(
          player_num, len(guessed_nums)))
    continue

if not rand_num in guessed_nums:
  print("Sorry! My number was {}.".format(rand_num))

Hi Ibs,

Don't worry! you will pick it up.

Kenneth's code looks a lot more but he is checking a few things to stop the program crashing and also giving the user a max number of tries.

Try is saying 'try this and if it goes wrong look at what 'except' is doing.

  try:
    player_num = int(guess)
  except:
    print("That's not a whole number!")
    break

then he checks that the user has entered a number in the range. It just looks more.

Reading over your code there is only one thing I would change. the variable you have called 'List'. Get out of the habit now of calling anything that is a list List or lst. The word list is reserved in python, call it something like guesses or tries and always lower case.

Have a think about how you could expand the program, it is within your reach!

Here is a link to a guess the number game on codeskulpter part of the Coursrea python course at Rice. It has lots of bells and whistles like keeping score etc.

I took this online course and I learnt a lot about coding for games and maths and yawn.... Kennith will show you how to build real world things that can really get you a job. Stick with it! You can do it, and the feeling you are going to get when you crack it, I do this silly little dance but that's way to much info.

Some ideas for you code.

import random


"""add a input so you can change the range of numbers. you can then store the max number
in a variable and test to see if any of the entries are with in range."""

random = random.randint(1, 10)  
guesses = []

while True:
    print("Guess the right number between 1 and 10")
    ask = input("> ")
    user_num = int(ask)

    # Expand code here.

    guesses.append(user_num)
    if user_num == random:
        print("Congrats! you have gussed the right number")
        break
    elif user_num > random:
        print("Too high")
        continue
    elif user_num < random:
        print("Too low")
        continue

"""make a test to see if its the minimum amount of tries needed. so if the random number is 8, 
math's wise you would look for that by deviding by 2 all the time. So, 5,7, and then either 8 or 9 
and you would could say, 4 tries is good, 3 tries is great"""

print("It took you {} tryes to guess the number".format(len(guesses)))

Thanks man. but what is Coursera? and can you learn programming in python there?.

You can learn python at coursera and other things too, however, I find the tuition here better and there is a lot of focus on maths and programming at coursrea, something that is not really needed in most function programming, its only really games or statistical/fiscal software and its really the games where the maths is hard, the stats stuff is done for you.

so what I am saying is you spend a lot of time messing around getting the maths right, when you are meant to be learning how to code.

I have doe Lynda.com too and this is by far the best. Stick with Kenneth he is really good and he is there to help too.

Thanks for the advice, i think i will stick with kenneth.
