Yury Selivanov e0b23095ee Issues #26289 and #26315: Optimize floor/modulo div for single-digit longs 
Microbenchmarks show 2-2.5x improvement.  Built-in 'divmod' function
is now also ~10% faster.

Victor Stinner a2724095cd compiler now ignores constant statements 
The compile ignores constant statements and emit a SyntaxWarning warning.

Don't emit the warning for string statement because triple quoted string is a
common syntax for multiline comments.

Don't emit the warning on ellipis neither: 'def f(): ...' is a legit syntax for
abstract functions.

Changes:

* test_ast: ignore SyntaxWarning when compiling test statements. Modify
  test_load_const() to use assignment expressions rather than constant
  expression.
* test_code: add more kinds of constant statements, ignore SyntaxWarning when
  testing that the compiler removes constant statements.
* test_grammar: ignore SyntaxWarning on the statement "1"
 2016-02-08 18:17:58 +01:00
Victor Stinner 51d8c526d5 Replace noop constant statement with expression 
* Constant statements will be ignored and the compiler will emit a
  SyntaxWarning.
* Replace constant statement (ex: "1") with an expression statement
  (ex: "x=1").
* test_traceback: use context manager on the file.

Issue #26204.

Martin Panter d5db14794b Issue #25179: Preparatory cleanup of existing docs on string formatting 
* Various sections were pointing to the section on the string.Formatter
  class, when the section on the common format string syntax is probably more
  appropriate
* Fix references to various format() functions and methods
* Nested replacement fields may contain conversions and format specifiers,
  and this is tested; see Issue #19729 for instance
