end_col_offset
Instances of :class:`ast.expr` and :class:`ast.stmt` subclasses have
- :attr:`lineno`, :attr:`col_offset`, :attr:`lineno`, and :attr:`col_offset`
- attributes. The :attr:`lineno` and :attr:`end_lineno` are the first and
- last line numbers of source text span (1-indexed so the first line is line 1)
- and the :attr:`col_offset` and :attr:`end_col_offset` are the corresponding
+ :attr:`lineno`, :attr:`col_offset`, :attr:`end_lineno`, and
+ :attr:`end_col_offset` attributes. The :attr:`lineno` and
+ :attr:`end_lineno` are the first and last line numbers of the source
+ text span (1-indexed so the first line is line 1), and the
+ :attr:`col_offset` and :attr:`end_col_offset` are the corresponding
UTF-8 byte offsets of the first and last tokens that generated the node.
The UTF-8 offset is recorded because the parser uses UTF-8 internally.
