# sympy__sympy-11897 ## Result The fix is complete. Here's a summary of the changes: ## Problem The LaTeX printer was inconsistent with the pretty printer when Piecewise functions appeared in multiplications. Specifically, when a Piecewise was not the last factor (e.g., `A * Piecewise(...)`), the LaTeX output omitted parentheses around the Piecewise, while the pretty printer would include them. ## Changes Made ### 1. `sympy/printing/latex.py` — `_needs_mul_brackets()` method - **Added** an unconditional check `if expr.is_Piecewise: return True` so that Piecewise expressions always get wrapped in `\left(...\right)` brackets when appearing in a multiplication, regardless of their position. - **Removed** `Piecewise` from the conditional list `(Integral, Piecewise, Product, Sum)` that only applied when `not last`, since Piecewise now always gets brackets. ### 2. `sympy/printing/tests/test_latex.py` — `test_latex_Piecewise()` - Updated `assert latex(A*p) == r"A %s" % s` to `assert latex(A*p) == r"A \left(%s\right)" % s` to reflect the new correct behavior. ## Result - `latex(A * Piecewise(...))` now correctly produces `A \left(\begin{cases}...\end{cases}\right)` instead of `A \begin{cases}...\end{cases}` — consistent with the pretty printer's behavior. - All 103 other LaTeX tests pass (the 2 pre-existing failures in `test_latex_Float` and `test_issue_8470` are unrelated Python 3.9 compatibility issues). ## Stop Reason: `end_turn` ## Token Usage - Input: 1507269 - Output: 15160 - Cache Read: 0 - Cache Creation: 0 ## Tool Calls (55 total) ### 1.
