get_item dynamodb with if else 条件如果项目匹配

Question

def main():
    alias = "jen"
    ddb = boto3.client("dynamodb")

    get_ddb_item = ddb.get_item(TableName="testtable", Key={"employee": {"S": alias}})

    item = get_ddb_item["Item"]
    print(item)

    if item == alias:
         print(f"{alias} is an employee")

    else:
         print(f"{alias} is not an active employee")

testtable上唯一的内容是PK: employee item: "jen" I am expecting an out put of jen is an employee

这是我上面的代码，它给了我相反的jen is not an active employee获得预期的 output 的正确方法是什么？

Answer 1

你得到这个是因为item != 'jen'

if item['employee']['S'] == alias:
     print(f"{alias} is an employee")

else:
     print(f"{alias} is not an active employee")
