Call Perl Script from Python: Complete Guide

To invoke a Perl script, you can use the subprocess module in Python. Here is an example code for calling a Perl script:

import subprocess

# 要调用的Perl脚本路径
perl_script = '/path/to/perl/script.pl'

# 调用Perl脚本并传递参数
args = ['arg1', 'arg2', 'arg3']
process = subprocess.Popen(['perl', perl_script] + args, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
output, error = process.communicate()

# 输出Perl脚本的执行结果
print(output.decode('utf-8'))
print(error.decode('utf-8'))

In the example above, we specify the path to the Perl script we want to call first. Then, we can use the subprocess.Popen function to start a new process, passing the perl command, script path, and arguments as parameters to it. The stdout=subprocess.PIPE and stderr=subprocess.PIPE parameters are used to capture the script’s output and error messages.

Finally, we can use the “communicate” method to obtain the output and error messages of the script, and use the “decode” method to convert byte data to string data for output to the console.

Please ensure that the Perl interpreter is properly installed before calling the Perl script, and replace the script path with your actual Perl script path.
