# Import the client models of the corresponding product module.
from tencentcloud.cvm.v20170312 import cvm_client, models
try:
    # Instantiate an authentication object. The Tencent Cloud account `secretId` and `secretKey` need to be passed in as the input parameters
    cred = credential.Credential("secretId", "secretKey")

    # Instantiate the client object of the requested product (with CVM as an example)
    client = cvm_client.CvmClient(cred, "ap-shanghai")

    # Instantiate a request object
    req = models.DescribeInstancesRequest()

    # Call the API you want to access through the client object. You need to pass in the request object
    resp = client.DescribeInstances(req)
    # A string return packet in JSON format is outputted
