在 python 的循环中每次生成一个随机数

Question

I am trying to simulate blobs reproducing and dying and every blob has a reproduction- and death chance. Every time in a loop it is supposed to generate a random rumber to see if the death and birth rate is bigger than the random number, if yes, create or delete a blob. every blob is stored in a list blobs.

THe problem is that it seems to generate 1 number for all blobs so eiter no one dies or everyone dies at once, but i want different randoms for each blob. For example reproduction -and deathchance are 0.5.

for blob in blobs:
        if blob.reproduce_chance > random.uniform(0,1):
            blobs.append(blob)
        if blob.death_chance > random.uniform(0,1):
            blobs.pop(blobs.index(blob))

import random

variation = 0

for blob in range(10):
        if 0.5 > random.uniform(0,1):
            print("New born at blob", blob)
            variation += 1
        if 0.5 > random.uniform(0,1):
            print("Death at blob", blob)
            variation -= 1
print("Blob count change:", variation)

Output:

Death at blob 1
New born at blob 2
Death at blob 2
New born at blob 4
Death at blob 4
New born at blob 5
Death at blob 5
New born at blob 6
Death at blob 6
New born at blob 7
New born at blob 8
Blob count change: 1

So the problem is not with the random number generator. As said in the comments, it may be due to changing a list while iterating over it.
