版本号解析的正则表达式

import re

version_regex = r'(\d+)\.(\d+)\.(\d+)'
version_string = '1.2.3'

match = re.match(version_regex, version_string)

if match:
    major_version = match.group(1)
    minor_version = match.group(2)
    patch_version = match.group(3)

    print(f'Major version: {major_version}, Minor version: {minor_version}, Patch version: {patch_version}')
else:
    print('Version string does not match the regular expression.')
