E-TE0607 — Wrong number of arguments to range

Error Type	Type Error
Phase	building expressions from Python
Python exception	`TypeError` (builtin)

Message

`jijmodeling.range` takes one, two, or three positional arguments.

Possible fix: call it in one of the following forms:
  - `range(stop)`
  - `range(start, stop)`
  - `range(start, stop, step)`

Cause

jm.range was called with no positional arguments, or with four or more. It mirrors Python’s built-in range and accepts exactly one, two, or three arguments: stop, start, stop, or start, stop, step.

Fix

Call it with one, two, or three integer-valued expressions:

N = problem.Natural("N")
jm.range(N)          # 0, 1, ..., N-1
jm.range(1, N)       # 1, 2, ..., N-1
jm.range(0, N, 2)    # 0, 2, 4, ..., N-1 or N-2

Each argument may be a plain number, a placeholder, or any expression evaluating to an integer without decision variables.
