如何在使用os时在python中传递当前日期。在python 2.7.5中用于将文件复制到gcs位置的系统

import os
import datetime
from google.cloud import storage

# 获取当前日期
current_date = datetime.datetime.now().strftime("%Y-%m-%d")

# 定义源文件和目标文件路径
source_file_path = "path/to/source/file.txt"
destination_file_path = f"gs://your-bucket-name/{current_date}/file.txt"

# 复制文件到GCS
def copy_file_to_gcs(source_path, destination_path):
    # 创建GCS客户端
    storage_client = storage.Client()

    # 获取目标bucket和blob对象
    destination_bucket_name, destination_blob_name = destination_path.replace("gs://", "").split("/", 1)
    destination_bucket = storage_client.bucket(destination_bucket_name)
    destination_blob = destination_bucket.blob(destination_blob_name)

    # 上传文件
    destination_blob.upload_from_filename(source_path)

    print(f"文件已成功复制到GCS位置：{destination_path}")

# 调用函数进行文件复制
copy_file_to_gcs(source_file_path, destination_file_path)
