如何用Python批量生成替换路径参数的script_N.aas文件？

Got it, this is a common batch file generation task—here's a reliable Python script that'll handle exactly what you need, making sure only those two specific path numbers get updated from 1 to 20.

Step-by-Step Explanation & Code #

First, we'll read the original script_1.aas file, then loop through numbers 1 to 20, replace the target path numbers, and write each new file. Using regular expressions ensures we only replace the digits in those exact path strings (avoiding accidental replacements elsewhere in the file).

import re

# Read the original file content
with open("script_1.aas", "r") as original_file:
    content = original_file.read()

# Loop from 1 to 20 to generate each file
for num in range(1, 21):
    # Replace both path numbers: "output\\script_1" → "output\\script_N" and "network\\script_1" → "network\\script_N"
    updated_content = re.sub(
        r'(output\\script_)\d+|(network\\script_)\d+',
        lambda match: f"{match.group(1) or match.group(2)}{num}",
        content
    )
    
    # Write the updated content to the new file
    with open(f"script_{num}.aas", "w") as new_file:
        new_file.write(updated_content)

Breakdown of the Code #

• Reading the Original File: We use a with statement to safely read script_1.aas—this ensures the file is closed automatically after reading, no need for manual cleanup.
• Regex Replacement: The regex pattern targets either output\\script_ followed by digits or network\\script_ followed by digits. The lambda function grabs the matching path prefix and appends the current loop number num to replace the old digit.
• Writing New Files: For each number from 1 to 20, we create a new file named script_{num}.aas and write the updated content to it.

This script will generate all 20 files with the exact content you need, only updating those two path parameters. Just make sure script_1.aas is in the same directory as your Python script when you run it!
