This is an example of representing a Zebra Puzzle using a Z3-based Python code:

There are 5 Producers in this puzzle.

Categories and possible items:
  - Shirt: black, green, orange, pink, red
  - Name: Barbara, Isabella, Jane, Nicole, Rachel
  - Jam: apricot, cherry, fig, raspberry, watermelon
  - Size: 10 oz, 12 oz, 14 oz, 20 oz, 6 oz
  - Source: backyard, farmers' coop, local grocer, organic farm, wild pickings

Clues:
 - The producer whose jam comes from Wild pickings is in the fourth position.
 - The producer selling Cherry jam is somewhere to the right of the one wearing a Green shirt.
 - Isabella is selling Cherry jam.
 - The producer wearing a Pink shirt is somewhere between the producer whose jam source is the Backyard and the one selling Watermelon jam, in that order.
 - The producer selling 14 oz jars is somewhere to the right of the one wearing a Green shirt.
 - The producer with 14 oz jars is next to the one selling Raspberry jam.
 - The Raspberry jam producer is positioned at one of the ends.
 - Barbara is next to the producer whose jam source is the Organic farm.
 - Jane is located somewhere between Nicole and Isabella, in that order.
 - The producer of Fig jam sources the fruit from an Organic farm.
 - The producer with 10 oz jars is at one of the ends.
 - The Raspberry jam producer is somewhere to the right of the one wearing a Green shirt.
 - The producer with 12 oz jars is next to the one who has 6 oz jars.
 - Isabella is next to the producer wearing a Black shirt.
 - The producer with 6 oz jars is next to the one whose source is the Local grocer.
 - The producer with 6 oz jars is in the second position.
 - Rachel's source of fruit is the Farmers' coop.
 - Barbara is next to Nicole.
 - The producer wearing an Orange shirt gets her fruit from the Backyard.
 - The producer with 12 oz jars is in the very first position.
