朱莉娅:有没有一个函数可以获取包的版本号？

import pkg_resources

def get_package_version(package_name):
    try:
        version = pkg_resources.get_distribution(package_name).version
        return version
    except pkg_resources.DistributionNotFound:
        return "Package not found"

# 示例：获取requests包的版本号
version = get_package_version("requests")
print(version)
