- Install packages
- Make network requests
- Access variables from previous blocks
- Export variables to be used in subsequent blocks
Limitations
- The execution time is limited to 5 minutes.
- The environment resets after each execution, so any installed packages or variables are not retained.
- Startup latency is ~200ms.
Example Code Snippet
Here is a simple example of using the Code Execution block:import json
import requests
from concurrent.futures import ThreadPoolExecutor
urls = ["https://paulgraham.com/reddits.html"]
print(urls)
# Function to fetch and return content for each URL
def fetch_url(url):
response = requests.get(url)
return response.text # Return the entire response text
# Create a ThreadPoolExecutor to execute requests in parallel
with ThreadPoolExecutor() as executor:
# Using map to fetch content for all URLs
results = list(executor.map(fetch_url, urls))
# Print the first 200 characters of each result for demonstration
for i, result in enumerate(results):
print(f"Content of {urls[i]}:\n{result[:200]}...\n")
Executing Commands
You can execute commands like installing packages using the! operator before the command.
!pip install requests
Keep commands in a separate block from code.
Packages
Several common packages are installed by default.requestspandasjson
