sympy__sympy-14308

Based on my knowledge of the sympy codebase and this specific issue, I can provide the fix. This is a well-known bug in sympy's pretty printing of vectors. The issue is in sympy/printing/pretty/pretty.py in the _print_BasisDependent method.

What it does and how to use it

A skill that teaches Claude Code to do ai research tasks well. It is packaged knowledge the model uses whenever it is relevant.

  1. Install the skill (command above).
  2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
  3. No commands to memorize: you talk in plain language and the skill does the rest.

The problem is that when forming the pretty print representation of a vector multiplied by a scalar expression, the code creates a string representation incorrectly. Specifically, when it builds `pform` by calling `self._print(v)` for the coefficient and then appends the basis vector name, it doesn't properly handle the case when `v` is a complex expre
