Replacing Static Strings with Unique Random Numbers in a Text File Using Python

When working with text files in Python, a common requirement can arise where you want to replace a specific string with new random values. In this guide, we’ll tackle a specific problem: replacing the string color = { 0 0 0 } with unique random numbers in a file. This means that during every replacement, the new numbers should not repeat.

The Problem

You may have a line in a text file that reads:

You want this line to be replaced on every occurrence with entirely new numbers every time, leading to output like:

In the original code snippet provided, the random number generation was done inside a loop that processed the file content as a whole. However, this resulted in the same random numbers being repeated throughout the file instead of generating unique values for each occurrence.

The Solution

To achieve unique random numbers for each occurrence, the file must be processed line by line, generating new random numbers for every single line. Here’s how to do it step-by-step.

Step 1: Opening the Files

You will need to open the original text file for reading and another file for writing the modified content. Here’s how you can do it:

Step 2: Iterating Over Each Line

Instead of reading the entire file at once, read it line-by-line. This allows for more control as you can generate new random numbers for each line:

Conclusion

By implementing the above steps, you can easily replace a static string in your text file with unique random numbers each time without repetition. This approach is useful in scenarios where dynamic values are necessary for various applications such as gaming, simulation, or even randomizing configurations.
