Question

There are multiple containers in each blob, I want to use the Python API to see the size of the specified container, how do I do it?

Welcome to Microsoft Q&A platform and thanks for posting your question here.

To get the size of a specified container in Azure Blob Storage using the Python API, you can list all the blobs in the container and sum up their sizes. Here’s a sample code snippet which will share the output in the terminal and also creates a file in the same directory where the script is stored:

from azure.storage.blob import BlobServiceClient
# Create the BlobServiceClient that is used to call the Blob service for the storage account
conn_str = '<update the connecion string>'
blob_service_client = BlobServiceClient.from_connection_string(conn_str=conn_str)
all_containers = blob_service_client.list_containers()
for container in all_containers:   
    # List the blobs in the container
    with open('output.txt', 'a') as file:
    # Write your output
        file.write("\nContainer Name : " + container['name'])
    print("\nContainer Name  : " + container['name'])
    container_name = container['name']
    container = blob_service_client.get_container_client(container=container_name)
    lblobs = container.list_blobs()

    # Initialize the size
    total_size = 0

    # Loop through each blob and add up the sizes
    for blob in lblobs:
        with open('output.txt', 'a') as file:    
            file.write("    \n\tBlob name: " + blob.name + " Blob size(bytes): "+ str(blob.size))  
        print("\tBlob name: " + blob.name + " Blob size(bytes): "+ str(blob.size))   
        total_size += blob.size
    with open('output.txt', 'a') as file:    
        file.write("\nTotal size of the container(bytes): " + container_name +" " + str(total_size)) 
    print("Total size of the container(bytes): " + container_name +" " + str(total_size))

Hope this helps. Thanks
