We need to translate the given English text into German, preserving the name "python-executor" only if it appears in the source text. The source text does not contain "python-executor" explicitly; it only appears in the instruction as the name to preserve, but not in the <text> block. So we should not include it. The translation should be accurate, keep technical terms, URLs, numbers, and product names. The text describes executing Python code in a sandboxed environment via inference.sh, lists pre-installed libraries, use cases, and triggers. Translate naturally into German. Key points: "safe sandboxed environment" -> "sicheren Sandkasten-Umgebung" or "sicheren isolierten Umgebung"? "Sandboxed" is often "Sandkasten" or "isoliert". "Pre-installed" -> "Vorinstalliert". "100+ more libraries" -> "über 100 weitere Bibliotheken". "Use for" -> "Verwendung für". "Triggers" -> "Auslöser" or "Trigger

Examples

Web Scraping

belt app run infsh/python-executor --input '{
  "code": "import requests\nfrom bs4 import BeautifulSoup\n\nresponse = requests.get(\"https://example.com\")\nsoup = BeautifulSoup(response.content, \"html.parser\")\nprint(soup.find(\"title\").text)"
}'

Data Analysis with Visualization

belt app run infsh/python-executor --input '{
  "code": "import pandas as pd\nimport matplotlib.pyplot as plt\n\ndata = {\"name\": [\"Alice\", \"Bob\"], \"sales\": [100, 150]}\ndf = pd.DataFrame(data)\n\nplt.bar(df[\"name\"], df[\"sales\"])\nplt.savefig(\"outputs/chart.png\")\nprint(\"Chart saved!\")"
}'

Image Processing

belt app run infsh/python-executor --input '{
  "code": "from PIL import Image\nimport numpy as np\n\n# Create gradient image\narr = np.linspace(0, 255, 256*256, dtype=np.uint8).reshape(256, 256)\nimg = Image.fromarray(arr, mode=\"L\")\nimg.save(\"outputs/gradient.png\")\nprint(\"Image created!\")"
}'

Video Creation

belt app run infsh/python-executor --input '{
  "code": "from moviepy.editor import ColorClip, TextClip, CompositeVideoClip\n\nclip = ColorClip(size=(640, 480), color=(0, 100, 200), duration=3)\ntxt = TextClip(\"Hello!\", fontsize=70, color=\"white\").set_position(\"center\").set_duration(3)\nvideo = CompositeVideoClip([clip, txt])\nvideo.write_videofile(\"outputs/hello.mp4\", fps=24)\nprint(\"Video created!\")",
  "timeout": 120
}'

3D Model Processing

belt app run infsh/python-executor --input '{
  "code": "import trimesh\n\nsphere = trimesh.creation.icosphere(subdivisions=3, radius=1.0)\nsphere.export(\"outputs/sphere.stl\")\nprint(f\"Created sphere with {len(sphere.vertices)} vertices\")"
}'

API Calls

belt app run infsh/python-executor --input '{
  "code": "import requests\nimport json\n\nresponse = requests.get(\"https://api.github.com/users/octocat\")\ndata = response.json()\nprint(json.dumps(data, indent=2))"
}'

File Output

Files saved to outputs/ are automatically returned:

# These files will be in the response
plt.savefig('outputs/chart.png')
df.to_csv('outputs/data.csv')
video.write_videofile('outputs/video.mp4')
mesh.export('outputs/model.stl')

Variants

# Default (8GB RAM)
belt app run infsh/python-executor --input input.json

# High memory (16GB RAM) for large datasets
belt app run infsh/python-executor@high_memory --input input.json

Use Cases

Web scraping - Extract data from websites
Data analysis - Process and visualize datasets
Image manipulation - Resize, crop, composite images
Video creation - Generate videos with text overlays
3D processing - Load, transform, export 3D models
API integration - Call external APIs
PDF generation - Create reports and documents
Automation - Run any Python script

Important Notes

CPU-only - No GPU/ML libraries (use dedicated AI apps for that)
Safe execution - Runs in isolated subprocess
Non-interactive - Use plt.savefig() not plt.show()
File detection - Output files are auto-detected and returned
