I am using a DynamoDB table named DMS in which I regularely update some values. Therefor I first save all values from an element in a variable called "response". The element has the Primary key 220 in my example. After this I save the value of the Attribute (in my case the element with the heading 522) in the variable CounterOnePlus and add 1. After this I try to update the given Attribute of the element in the column 522. Here is my Code:
import boto3
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('DMS')
AverageValue=220
DeltaValue=522
response = table.get_item(
Key=
'Average': '%d' % AverageValue,
)
item = response['Item']
CounterOnePlus=int(item['%d' % DeltaValue])+1
print(CounterOnePlus)
table.update_item(
Key=
'Average': '%d' % AverageValue,
,
UpdateExpression='SET 522 = :val1',
ExpressionAttributeValues=
':val1': CounterOnePlus
)The Problem I am facing is, that I am not able to save the values. The reason for this is the Name of the heading, wich is 522. Whenever I insert the value to a column with a string Header like "hallo", the value gets updated. Changing the value 522 to a string with the str(522) does not Change anything. My error message is the following:
