Parser.
parse_tuple
(simplified=False, with_condexpr=True, extra_end_rules=None, explicit_parentheses=False)[source]¶ Works like parse_expression but if multiple expressions are delimited by a comma a
Tuple
node is created. This method could also return a regular expression instead of a tuple if no commas where found.The default parsing mode is a full tuple. If simplified is True only names and literals are parsed. The no_condexpr parameter is forwarded to
parse_expression()
.Because tuples do not require delimiters and may end in a bogus comma an extra hint is needed that marks the end of a tuple. For example for loops support tuples between for and in. In that case the extra_end_rules is set to
['name:in']
.explicit_parentheses is true if the parsing was triggered by an expression in parentheses. This is used to figure out if an empty tuple is a valid expression or not.
