生成具有多个键的 DynamoDB put_item

Question

I am followingthis tuto . I need to do the same with a csv that contains 120 columns. In the tuto, Keys for items are given manually. Is there any way to do that automatically? I already have a list with the csv columns that I can use. All of my columns are Strings. This is the block I want to automatize:

response = dyndb.put_item(
                TableName='emplist',
                Item={
                'empid' : {'N':str(empid)},
                'name': {'S':name},
                'salary': {'N':str(salary)},
                'parttime': {'BOOL':False},
                }
            )

My column names list is:

columns = ['A', 'B', 'C', ...... ]

Answer 1

Unfortunately, as the types can differ, it is best do it manually for some columns. Check which one is predominant, automate that and do manually the rest.

Let's assume 'S' is found in ~90 columns.

for index, row_item in enumerate(row):
    items_dict['column_' + i] = {'S': row_item}

# now manually replace the ones with a different type or that have additional parsing
item_dict['column_4'] = {'N': int(row[4])}
...

# if you want different key names do:
item_dict['name'] = item_dict['column_5']
del item_dict['column_5']

response = dyndb.put_item(
            TableName='emplist',
            Item=item_dict
        )
