Problem Statement − Use boto3 library in Python to check whether a glue job exists or not. For example, check whether run_s3_file_job exists in AWS glue or not.Approach/Algorithm to solve this problemStep 1 − Import boto3 and botocore exceptions to handle exceptions.Step 2 − job_name is the parameters in function.Step 3 − Create an AWS session using boto3 library. Make sure region_name is mentioned in default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.Step 4 − Create an AWS client for glue.Step 5 − Now use the get_job function and pass the JobName.Step 6 ...
