如何从 Python 中的 Azure 存储资源管理器中读取文件作为函数？

Question

I want to convert the following code as a function so that it can replicated to read multiple files:

data = container.download_blob(data)
try:
    print ("Reading the Grower data from blob")
    df  =  pd.read_csv(BytesIO(data.readall()))
    print ("Data read successfully")    
except Exception as e:
    print ("Data load failed due to :" + str(e))

I created the following function:

def download_func(filename,dataframe):
    filename = container.download_blob(filename)
    try:
        print ("Reading the Data from blob")
        dataframe  =  pd.read_csv(BytesIO(filename.readall()))
        print (str(filename)+" data read successfully")    
    except Exception as e:
        print (str(filename)+" data load failed due to :" + str(e))
download_func(data,df)

but there is a name error coming for df

How can I proceed from here? Would be grateful for any help!

• You can read the files from azure storage explorer in python as a function check the Azure Storage SDK for Python

from azure.storage.blob import BlockBlobService

block_blob_service = BlockBlobService(account_name='myaccount', account_key='mykey')

block_blob_service.get_blob_to_path('mycontainer', 'myblockblob', 'out-sunset.png')

• for more information you can go through the SDK documentation
