def lambda_handler(event, context):
    parameter = client.get_parameter(Name='otherparam', WithDecryption=True)
    #print(parameter)
    return parameter ['Parameter']['Value']
    #file = open("/sample.txt", "w")
    #file.write(parameter)
    #file.close
    with open("/tmp/log.txt", "w") as f:
        file.write(parameter)
    
    s3.upload_file("/tmp/log.txt", "copys3toecsbucket-117", "logs.txt")
    #bucket = "copys3toecsbucket-117"
