This is the tutorial text:
>>> prefix = 'Py'
>>> prefix 'thon' # can't concatenate a variable and a string literal
...
SyntaxError: invalid syntax
>>> ('un' * 3) 'ium'
...
SyntaxError: invalid syntax
This is the actual result:
>>> prefix = 'Py'
>>> prefix 'thon' # can't concatenate a variable and a string literal
File "<stdin>", line 1
prefix 'thon' # can't concatenate a variable and a string literal
^
SyntaxError: invalid syntax

The output in tutorial is correct. "..." means omitted output (we don't want to clutter examples with insignificant details). |

But it also contains an error message part which has nothing to do with
this example (marked in dark green)
This only works with two literals though, not with variables or expressions:
>>> prefix = 'Py'>>> prefix 'thon' # can't concatenate a variable and a string literal ...SyntaxError: invalid syntax>>> ('un' * 3) 'ium' ...SyntaxError: invalid syntax
If you want to concatenate variables or a variable and a literal, use +:

@serhiy I think Amit wants to say there is no triple point in these examples of the tutorial. |

and when you execute the examples, the REPL does not generate the triple points. For me, the examples of the tuto are correct and we don't need to add '...' in the examples. |

@Amit Please confirm docs.python.org before submitting issue. #33460 fixed it already. |

Uh! You meant Python 2.7!! It doesn't make sense to improve Python 2.7 tutorial. If you're reading Python 2 tutorial, please read 3.7 tutorial instead!!! |
