Add support for Python 3.14 multi-exception syntax #10546
Description
Python 3.14 relaxes the syntax for except clauses that accept multiple exception types but do not use an as clause. Previously, parentheses were required in this case, but 3.14 eliminates this requirement.
def divide(a, b):
try:
result = a / b
return result
except ZeroDivisionError, TypeError: # No Parens needed here (unless there's an as clause)
print(f"Wrong input: {a} and {b}")
raiseSee PEP 758 for details.
