This is what your code looks like after prefixing with ‘’’python and suffixing with ‘’’ (where back tics were used instead of single quotes): def factor_subexpressions(expr): """Factors all subexpressions of a SymPy expression. Args: expr: A SymPy expression. Returns: A SymPy expression with all subexpressions factored. """ if isinstance(expr, sp.Add): return sp.Add(*[arg.factor() for arg in expr.args]) elif isinstance(expr, sp.Mul): return sp.Mul(*[arg.factor() for arg in expr.args]) else: return sp.factor(expr) On Tuesday, May 21, 2024 at 10:30:18 AM UTC-5 Chris Smith wrote:
