存储在 GCS 存储桶中时无法重命名文件

Question

我想在 GCS 中存储文件时重命名文件 bucket.I 参考了此文档：
How to rename a file while storing it to a GCS bucket

它给出了 error.I 不确定我是否修改了它 correfctly.Entry 点是 new_func.This 是下面的代码：

def new_func(event,context):
    bucket_name: 'poc_bucket_testing'
    blob_name:  'poc_bucket_testing/republic_txttocsv.txt'          
    new_blob_name: 'target_bucket/republic_txttocsv.csv'    
    rename_blob(bucket_name,blob_name,new_blob_name);

def rename_blob(bucket_name,blob_name,new_blob_name):       
    print("inside");
    bucket = storage_client.bucket(bucket_name)
    blob = bucket.blob(blob_name)
    new_blob = bucket.rename_blob(blob,new_blob_name)        
    return new_blob.public_url

给出错误 below.I 也尝试在 rename_blob 中分配它并给出相同的错误。

"Traceback (most recent call last):

您正在使用冒号（如在字典中）而不是赋值运算符：

def new_func(event,context):
    bucket_name = 'poc_bucket_testing'
    blob_name =  'poc_bucket_testing/republic_txttocsv.txt'          
    new_blob_name = 'target_bucket/republic_txttocsv.csv'    
    rename_blob(bucket_name,blob_name,new_blob_name)
