我正在尝试获得所有OnDemand /共享租赁/非RI实例的pricePerUnit：USD每小时费用;每种类型一个价格。以下代码是我目前的代码：
import boto3
import sys
client = boto3.client('pricing')
response = client.get_products(
ServiceCode='AmazonEC2',
Filters=[
{'Type': 'TERM_MATCH', 'Field': 'instanceType', 'Value': 'm4.xlarge' },
{'Type' :'TERM_MATCH', 'Field':'operatingSystem', 'Value': 'Windows' },
{'Type' :'TERM_MATCH', 'Field':'location', 'Value': 'US East (N. Virginia)' },
{'Type' :'TERM_MATCH', 'Field':'tenancy', 'Value': 'Shared' },
{'Type' :'TERM_MATCH', 'Field':'rateCode', 'Value': 'Q49VKFFWC877GUFC.JRTCKXETXF.6YS6EN2CT7' }
],
FormatVersion='aws_v1'
)
我正在使用此代码块来检索美元价值：
for key, values in response.items():
if key == 'PriceList':
for x in values:
print(float(x['USD']), 2)
不幸的是我收到了这个错误：
Traceback (most recent call last):
File "C:\bin\AWSpricing.py", line 31, in <module>
print(float(x['USD']), 2)
TypeError: string indices must be integers
感谢您提供任何帮助。
答案 0 :(得分：1)
您的代码没有意义。
响应的内容是多维的。您需要遍历树以进入相应的USD字段：
