How to count numbers

I want to be able to count how much 1,2,3...100s are on my list. I tried a for loop, but it didn't work. Code:

import os
import random
list = [1, 2]

# print numbers

list.insert(1, random.randrange(100))

for x in range(1000):
  list.insert(1, random.randrange(100))

print(list)

output:
