| What was the outcome of the 1904 US Presidential election? |
The **1904 U.S. presidential election** resulted in a decisive
victory for the **incumbent Republican President Theodore Roosevelt**,
who was seeking a full term in his own right after succeeding the
assassinated William McKinley in 1901. Here are the key details of the
outcome: --- ### **Results at a Glance** - **Winner:** **Theodore
Roosevelt** (Republican) - **Opponent:** **Alton B. Parker** (Democrat)
- **Electoral Vote:** - Roosevelt: **336** electoral votes - Parker:
**140** ...... t by supporting William Howard Taft’s candidacy (though
he later ran again in 1912 with the Bull Moose Party). - The election
solidified Roosevelt’s control of the Republican Party and marked the
continued dominance of Republicans in national politics (they had won
every presidential election since 1896 except 1912). In short, the 1904
election was a **major personal triumph for Theodore Roosevelt**,
affirming his progressive leadership and giving him a powerful mandate
for his second term. |

Pixeltable’s Deepseek integration enables you to access Deepseek’s LLM
via the Deepseek API.
### Prerequisites
* A Deepseek account with an API key ([https://api-docs.deepseek.com/](https://api-docs.deepseek.com/))
### Important notes
* Deepseek usage may incur costs based on your Deepseek plan.
* Be mindful of sensitive data and consider security measures when
integrating with external services.
First you’ll need to install the required libraries and enter a Deepseek
API key. Deepseek uses the OpenAI SDK as its Python API, so we need to
install it in addition to Pixeltable.
```python theme={null}
%pip install -qU pixeltable openai
```
```python theme={null}
import getpass
import os
if 'DEEPSEEK_API_KEY' not in os.environ:
os.environ['DEEPSEEK_API_KEY'] = getpass.getpass('Deepseek API Key:')
```
Now let’s create a Pixeltable directory to hold the tables for our demo.
```python theme={null}
import pixeltable as pxt
# Remove the 'deepseek_demo' directory and its contents, if it exists
pxt.drop_dir('deepseek_demo', force=True)
pxt.create_dir('deepseek_demo')
```
Connected to Pixeltable database at: postgresql+psycopg://postgres:@/pixeltable?host=/Users/asiegel/.pixeltable/pgdata
Created directory 'deepseek\_demo'.
\
## Messages
Create a Table: In Pixeltable, create a table with columns to represent
your input data and the columns where you want to store the results from
Deepseek.
```python theme={null}
from pixeltable.functions import deepseek
# Create a table in Pixeltable and add a computed column that calls Deepseek
t = pxt.create_table('deepseek_demo/chat', {'input': pxt.String})
msgs = [{'role': 'user', 'content': t.input}]
t.add_computed_column(
output=deepseek.chat_completions(messages=msgs, model='deepseek-chat')
)
```
Created table 'chat'.
Added 0 column values with 0 errors in 0.01 s
No rows affected.
```python theme={null}
# Parse the response into a new column
t.add_computed_column(response=t.output.choices[0].message.content)
```
Added 0 column values with 0 errors in 0.01 s
No rows affected.
```python theme={null}
# Start a conversation
t.insert(
[
{
'input': 'What was the outcome of the 1904 US Presidential election?'
}
]
)
t.select(t.input, t.response).show()
```
Inserted 1 row with 0 errors in 18.72 s (0.05 rows/s)
