I am new to Python and need help regarding assigning numbers to variables. How would I assign a random number from 0 to 9 to the variables "a" through "j" so that each variable gets a random number with no duplicates? Thanks in advance!

You could do something like this to return a dictionary where the letters have been randomly mapped to numbers as well. It's a bit longer than other answers, but maybe easier for a beginner to follow the logic

import random

numbers_list = []
combined = {}
alphabet = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j']
while True:
    number = random.randint(0, 9)
    if number in numbers_list:
        pass
    else:
        numbers_list.append(number)
        combined.update({alphabet.pop(): number})
    if len(numbers_list) == 10:
        break

Here's one way:

import random

vals = list(range(10))
random.shuffle(vals)
a,b,c,d,e,f,g,h,i,j = vals

  • The best way, though making many variables is ill-advised. Short and clear; it's a shame someone downvoted it. – iz_ Jan 29 '19 at 00:50
  • I agree with the many variable thing, but it's OP's request... So to OP: you probably want to restructure your code to use `vals[x]` directly rather than defining 10 variables. – Julien Jan 29 '19 at 00:51

    Or maybe `dict(zip('abcdefg', vals))` if you wanted to call them by name. – iz_ Jan 29 '19 at 01:04
  • Do you know how I would make it so that the program does not repeat the same assignments to all of the variables again? A number could be assigned to the same variable again, however just not all ten numbers to the same variable. – Jason Le Feb 02 '19 at 02:24
  • I don't understand, please clarify exactly (example?) what's not satisfying you with my answer. – Julien Feb 03 '19 at 04:24
