Code:

from random import shuffle

numbers = list(range(100))
shuffle(numbers)
while numbers:
number = numbers.pop()
print(number)

1) Create a list of numbers from 0 to 99
2) Shuffle them with one of functions from random module
3) Pop the last item from the list until it is empty

Please note that random uses pseudorandom algorithm, for any serious randomization use secrets module or os.urandom().

I don't know what is your main goal. But i did quick change to your code and this should do what you want.

Code:

import random

elements = []

while len(elements) < 100:
selection = random.randint(1, 100)
print(selection)
if selection not in elements:
elements.append(selection)
print(elements)

Here's snippet of the output,

Code:

22
[22]
14
[22, 14]
...
76
[22, 14, 4, 45, 39, 51, 36, 30, 94, 41, 73, 32, 89, 100, 64, 18, 6, 16, 46, 52, 98, 71, 58, 62, 33, 17, 29, 56, 9, 25, 83, 53, 28, 72, 37, 86, 31, 61, 15, 26, 99, 70, 84, 66, 93, 79, 48, 34, 78, 90, 97, 49, 75, 54, 55, 13, 85, 20, 7, 96, 81, 68, 57, 60, 74, 11, 91, 69, 1, 40, 65, 21, 12, 63, 87, 5, 92, 77, 24, 44, 67, 3, 8, 35, 50, 42, 38, 23, 10, 76, 95, 2, 59, 27, 47, 82, 88, 19, 43]
80
[22, 14, 4, 45, 39, 51, 36, 30, 94, 41, 73, 32, 89, 100, 64, 18, 6, 16, 46, 52, 98, 71, 58, 62, 33, 17, 29, 56, 9, 25, 83, 53, 28, 72, 37, 86, 31, 61, 15, 26, 99, 70, 84, 66, 93, 79, 48, 34, 78, 90, 97, 49, 75, 54, 55, 13, 85, 20, 7, 96, 81, 68, 57, 60, 74, 11, 91, 69, 1, 40, 65, 21, 12, 63, 87, 5, 92, 77, 24, 44, 67, 3, 8, 35, 50, 42, 38, 23, 10, 76, 95, 2, 59, 27, 47, 82, 88, 19, 43, 80]

hi possible to generate a number by deleting what has already been generated in python without list

try :

Code:

import random

elements = str(random.randint(1, 100))

i = 0
while i != 100:
   selection = elements

   print(elements)
   print(selection)
   i = i + 1
   elements.remove(selection)

result File "1.py", line 12, in
elements.remove(selection)
AttributeError: 'str' object has no attribute 'remove'
