Ticket #30289, comment 3
v2 v3 1 Nevertheless, the error message is somewhat strange: 1 Ah okay, it's the variable `coords2`. The bug can be fixed very quickly. 2 2 3 {{{ 4 sage: R.<t> = RealLine() 5 sage: I = R.open_interval(0, 2*pi) 6 sage: J = R.open_interval(2*pi, 6*pi) 7 sage: h = J.continuous_map(I, ((t-2*pi)/2,), name='h') 8 sage: c_I = I.atlas()[0] 9 sage: c_J = J.atlas()[0] 10 sage: coord_func = h.coord_functions(c_J, c_I) 11 sage: expression = coord_func.expr() 12 sage: type(expression) 13 <class 'tuple'> 14 }}} 15 16 The variable `expression` should be a tuple and hence be subscriptable. 3 My other points still stand for discussion. :)
