How to put Items into DynamoDB table using python? - amazon-web-services

Question

I'm trying to put an Item into an Amazon DynamoDB table using a python script, but when I run the python script I get following error:
Traceback (most recent call last):
File "./table.py", line 32, in <module>
item.put(None, None)

import boto.dynamodb
conn = boto.dynamodb.connect_to_region('us-west-2', aws_access_key_id=<My_access_key>, aws_secret_access_key=<my_secret_key>)
entity = conn.create_schema(hash_key_name='RPI_ID', hash_key_proto_value=str, range_key_name='PIC_ID', range_key_proto_value=str)
table = conn.create_table(name='tblSensor', schema=entity, read_units=10, write_units=10)
item_data = {
'Pic_id': 'P100',
'RId': 'R100',
'Temperature': '28.50'
}
item = table.new_item(
# Our hash key is 'forum'
hash_key='RPI_ID',
# Our range key is 'subject'
range_key='PIC_ID',
# This has the

)
item.put() // I got error here.

I ran your code in my account and it worked 100% perfect, returning:
{u'ConsumedCapacityUnits': 1.0}
You might want to check that you are using the latest version of boto:
pip install boto --upgrade

I searched on google and solved my that problem. I have set correct time and date on my raspberry pi board and run that program, it's working fine.
