Random data generation sum to 1 by rounding

[juniorcoder]

Hello everyone,
I need a small help. I need to generate random values between 0 and 1. They must be successively ordered. Let me give you an example. Starting index is 3 and ending index 5, so in an array who has 10 index, they must be ordered like this:

A=[0 0 0.2 0.3 0.5 0  0 0 0 0]

Actually I do it in my code, I generate an array whose elements 0. Then I delete the part including the dtating and ending index and I insert to that part randomly generated value list (whose sum is equal to 1 for sure ). I generate these random values with the following code:

    def sum_to_x(n, x):
         values = [0.0, x] + list(np.random.uniform(low=0.0,high=x,size=n-1))
         values.sort()
         return [values[i+1] - values[i] for i in range(n)]

The problem my values are not rounded at all. I obtain something like that

Output:
[0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.29047860679220283 0.002342106757806439 0.5462946648931827 0.16088462155680805]

How can I round them (two decimal for example) by keeping their sum to 1, still?

Thank you so much in advance
