GitHub - heitzmann/gdspy: Python module for creating GDSII stream files, usually CAD layouts.

import gdspy

# The GDSII file is called a library, which contains multiple cells.
lib = gdspy.GdsLibrary()

# Geometry must be placed in cells.
cell = lib.new_cell('FIRST')

# Create the geometry (a single rectangle) and add it to the cell.
rect = gdspy.Rectangle((0, 0), (2, 1))
cell.add(rect)

# Save the library in a file called 'first.gds'.
lib.write_gds('first.gds')

# Optionally, save an image of the cell as SVG.
cell.write_svg('first.svg')

# Display all cells using the internal viewer.
gdspy.LayoutViewer()
