When a starred expression like *[0, 1] is parsed, the following AST gets generated: Module( body=[ Expr( value=Starred( value=List( elts=[ Constant( value=0, kind=None, lineno=1, col_offset=2, end_lineno=1, end_col_offset=3, ), Constant( value=1, kind=None, lineno=1, col_offset=5, end_lineno=1, end_col_offset=6, ), ], ctx=Load(), lineno=1, col_offset=1, end_lineno=1, end_col_offset=7, ), ctx=Load(), lineno=1, col_offset=0, end_lineno=1, end_col_offset=7, ), lineno=1, col_offset=0, end_lineno=1, end_col_offset=7, ) ], type_ignores=[], ) But, when a starred expression is an argument to a function call then the line/col info are wrong (end_col_offset is always equal to col_offset + 1): Module( body=[ Expr( value=Call( func=Name( id="f", ctx=Load(), lineno=1, col_offset=0, end_lineno=1, end_col_offset=1 ), args=[ Starred( value=List( elts=[ Constant( value=0, kind=None, lineno=1, col_offset=4, end_lineno=1, end_col_offset=5, ), Constant( value=1, kind=None, lineno=1, col_offset=7, end_lineno=1, end_col_offset=8, ), ], ctx=Load(), lineno=1, col_offset=3, end_lineno=1, end_col_offset=9, ), ctx=Load(), lineno=1, col_offset=2, end_lineno=1, end_col_offset=9, ) ], keywords=[], lineno=1, col_offset=0, end_lineno=1, end_col_offset=10, ), lineno=1, col_offset=0, end_lineno=1, end_col_offset=10, ) ], type_ignores=[], )
