使用boto3命令作为字符串

Question

We can use boto3 package to get the data from mTurk account (or do anything else in AWS). For example:

client = boto3.client('mturk')
balance = client.get_account_balance()

Is there a way to use boto3 command as a string? Something like:

balance = client.get_command('get_account_balance')

get_command is totally just for illustrative purposes here of course.

Answer 1

使用getattr内置函数：

getattr(client, 'get_account_balance')()

Answer 2

You could use the built-in getattr :

def get_command(client, command):
    return getattr(client, command)()
