Replace same string with random numbers on the same file

I want to be able to replace the same set of string to random new unique numbers.

From:

color = { 0 0 0 }

To:

color = { 2 5 10 }

color = { 1 59 102 }

color = { 9 72 200 }

On each line of the text file.

Here's my python code.

import random

for i in range(0, 10):
    x = str(random.randrange(0, 256))
    y = str(random.randrange(0, 256))
    z = str(random.randrange(0, 256))

    with open("9.txt", "r") as file:
        file_data = file.read()

    file_data = file_data.replace("color = { 0 0 0 }", "color = { " + x + " " + y + " " + z + " }")

    with open("colored.txt", "w") as file:
        file.write(file_data)

This code changes all correctly but to the same values and I want it to be unique numbers.

You need to process the file line by line, not all at once, and generate new random numbers for each line.

with open("9.txt", "r") as infile, open("colored.txt", "w") as outfile:
    for line in infile:
        x = str(random.randrange(0, 256))
        y = str(random.randrange(0, 256))
        z = str(random.randrange(0, 256))
        line = line.replace("color = { 0 0 0 }", f'color = {{ {x} {y} {z} }}')
        outfile.write(line)
