如何通过Python执行指定路径下的Perl脚本ProcessServerData.pl？

Hey there! Running a Perl script from Python is totally doable with Python's built-in subprocess module—let's break down how to handle your specific case, especially those tricky spaces in your file paths:

The key is to safely handle spaces in paths and use subprocess to invoke the Perl interpreter with your script. Here's a complete example:

import subprocess
import shlex

# Define the full path to your Perl script (raw string avoids backslash escape issues)
perl_script_path = r"C:\Users\Gurpreet Singh\Desktop\Amar_AG\KA03MM7155\ProcessServerData.pl"

# Safely quote the path to handle spaces without breaking the command
quoted_script = shlex.quote(perl_script_path)

# Run the Perl script
try:
    # Assuming Perl is in your system's PATH; if not, replace "perl" with the full path to perl.exe
    result = subprocess.run(
        ["perl", quoted_script],
        check=True,  # Throws an error if the Perl script exits with a failure code
        capture_output=True,  # Captures stdout/stderr for later use
        text=True  # Returns output as plain strings instead of bytes
    )

    # Print output from the Perl script if you need it
    print("Perl Script Output:\n", result.stdout)
    if result.stderr:
        print("Perl Script Warnings/Errors:\n", result.stderr)
except subprocess.CalledProcessError as e:
    print(f"Error running Perl script: {e.stderr}")

• Raw String Paths: The r prefix on the path ensures Windows backslashes aren't treated as escape characters.
• Path Quoting: shlex.quote() wraps the path in quotes automatically, so spaces in usernames/directories don't split the command incorrectly.
• Perl Path: If Perl isn't in your system's PATH, replace "perl" with the full path to your perl.exe (e.g., r"C:\Perl\bin\perl.exe").
• Arguments: If your Perl script needs command-line arguments, just add them to the list passed to subprocess.run()—like ["perl", quoted_script, "arg1", "arg2"].
