从SVN部署的任何建议,版本号自动写入我的代码？

import os
import re
import subprocess

# 获取SVN的版本号
def get_svn_version():
    try:
        output = subprocess.check_output(['svn', 'info'])
        version = re.search(r'Revision: (\d+)', output).group(1)
        return version
    except:
        return None

# 将版本号写入代码
def write_version_to_code(version):
    with open('version.py', 'w') as f:
        f.write(f'VERSION = "{version}"')

# 获取SVN版本号并写入代码
version = get_svn_version()
if version:
    write_version_to_code(version)
