...inputsizes(sizes) (Note: this method is not well-defined yet.) This can be used before a call to execute() to predefine memory areas for the operation's parameters. sizes is specified as a tuple -- one item for each input parameter. The item should be a Type object that corresponds to the input that will be used, or it should be an integer specifying the maximum length of a string parameter. If the item is None, then no predefined memory area will be reserved for that column (this is useful ...
...input process for acquiring forecasts, an input process for acquiring measured climatological data, the data aggregation engine, and the web application framework. There are two main input processes in the system: The forecast parser, and the actuals parser. The forecast parser is responsible for requesting forecasts from the web for each of the forecast providers ForecastWatch.com tracks. It parses the forecast from the page and inserts the forecast data into a database until it can be compared...
...input file will cause the SyntaxError exception to be raised. parseGrammarString (text) -> AST The parseGrammarString() function will follow the semantics of the parseGrammarFile(), but accept the grammar text as a string for input, as opposed to the file name. buildParser (grammarAst) -> DFA The buildParser() function will accept an AST object for input and return a DFA (deterministic finite automaton) data structure. The DFA data structure will be a C extension class, much like the ...
...input the full range of Unicode characters at the default Windows console. This also requires a subtle change to how the tokenizer parses text from readline hooks. Specific Changes Add _io.WindowsConsoleIO Currently an instance of _io.FileIO is used to wrap the file descriptors representing standard input, output and error. We add a new class (implemented in C) _io.WindowsConsoleIO that acts as a raw IO object using the Windows console functions, specifically, ReadConsoleW and WriteConsoleW. ...
...input data (called plaintext) in some way that is dependent on a variable key, producing ciphertext. The transformation can easily be reversed if and only if one knows the key. The key is a sequence of bits chosen from some very large space of possible keys. There are two classes of encryption algorithms: block ciphers and stream ciphers. Block ciphers encrypt multibyte inputs of a fixed size (frequently 8 or 16 bytes long), and can be operated in various feedback modes. The feedback modes s...
...input, once per improperly encoded input file. Remove the warning, and change the default encoding to "ascii". The builtin compile() API will be enhanced to accept Unicode as input. 8-bit string input is subject to the standard procedure for encoding detection as described above. If a Unicode string with a coding declaration is passed to compile(), a SyntaxError will be raised. SUZUKI Hisao is working on a patch; see [2] for details. A patch implementing only phase 1 is available at [1]. P...
...input from the wider community. Several people chimed in with their opinions, and Guido told us to go off and figure out a solution, then report back to python-dev. Comparing some libraries I decided the only fair way to compare various libraries is to implement the same command-line interface with several of them. Here are the results of that experiment. Optik, renamed to optparse, was added to Python 2.3's standard library.
...inputs are C/C++ header files with markup or Java source files. It can output HTML and LaTeX. (No real examples of input sources online.) DocJet (commercial) Documentation tool for C, C++, Java, MS IDL, and Visual Basic. The comments look pretty reasonable; it looks like a good bit of effort goes into identifying identifiers in the comment text and turning them into hyperlinks. Examples of marked s...
...input will never cause a segmentation fault. Instead, when the interpreter discovers an error, it raises an exception. When the program doesn't catch the exception, the interpreter prints a stack trace. A source level debugger allows inspection of local and global variables, evaluation of arbitrary expressions, setting breakpoints, stepping through the code a line at a time, and so on. The debugger is written in Python itself, testifying to Python's introspective power. On the other han...
...input string as its argument, and yields one of the following results: A "success" result. This result indicates that the expression can be parsed by that rule and the function may optionally move forward or consume one or more characters of the input string supplied to it. A "failure" result, in which case no input is consumed. Notice that "failure" results do not imply that the program is incorrect or a parsing failure because as the choice operator is ordered, a "failure" result merely indi...

...input influences the outcome, so that hash(b'\00') != hash(b'\x00\x00'). The internal interface code between the hash function and the tp_hash slots implements special cases for zero length input and a return value of -1. An input of length 0 is mapped to hash value 0. The output -1 is mapped to -2. Current implementation with modified FNV CPython currently uses a variant of the Fowler-Noll-Vo hash function [fnv]. The variant is has been modified to reduce the amount and cost of hash collisio...

...Input This PEP does not specify how a locker gets its input. An initial suggestion was to partially reuse PEP 621, but due to disagreements on how flexible the potential input should be in terms of specifying things such as indexes, etc., it was decided this would best be left to a separate PEP. Allowing Source Distributions and Source Trees to be an Opt-In, Supported File Format After extensive discussion, it was decided that this PEP would not support source distributions (aka sdists) or sou...

...input and by repr(). Warnings are enabled about operations that will change their numeric outcome in stage 2B, in particular hex() and oct(), %u, %x, %X and %o, hex and oct literals in the (inclusive) range [sys.maxint+1, sys.maxint*2+1], and left shifts losing bits. The new semantic for these operations are implemented. Operations that give different results than before will not issue a warning. The trailing L is dropped from repr(), and made illegal on input. (If possible, the long type comp...
