Guido van Rossum	fa4ac71dd6	Small changes to map() and filter(): (1) If a sequence S is shorter than len(S) indicated, don't fail -- just use the shorter size. (I.e, len(S) is just a hint.) (2) Implement the special case map(None, S) as list(S) -- it's faster.	28 years ago
Guido van Rossum	8ea9f4d10a	Fix a stupid little bug: len() of an unsized returns -1 and leaves an exception waiting to happen next...	28 years ago
Guido van Rossum	950ff2923a	Experimental feature: add default argument to getattr().	28 years ago
Guido van Rossum	f9d9c6c5d2	Added doc strings.	28 years ago
Guido van Rossum	d9b5208e90	In raw_input(prompt), make sure that str(prompt) really a string object before using it.	28 years ago
Guido van Rossum	9396673a58	Remove a few unused locals (I love VC++ for this!).	28 years ago
Guido van Rossum	09df08a105	A bunch of functions are now properly implemented in abstract.c, and the code here becomes much simpler. In particular: abs(), divmod(), pow(), int(), long(), float(), len(), tuple(), list(). Also make sure that no use of a function pointer gotten from a tp_as_sequence or tp_as_mapping structure is made without checking it for NULL first. A few other cosmetic things, such as properly reindenting slice().	28 years ago
Guido van Rossum	1e162d3753	Implement round() slightly different, so that for negative ndigits no additional errors happen in the last step. The trick is to avoid division by 0.1n -- multiply by 10.0n instead.	28 years ago
Guido van Rossum	a937d14898	Fred's right -- we need PyList_SET_ITEM().	28 years ago
Guido van Rossum	507338e5ca	In-line the code in range() to set the list items; there's really no need to call PyList_SetItem(v,i,w) when PyList_GET_ITEM(v,i)=w {sic} will do.	28 years ago
Guido van Rossum	730806d3d9	Make new gcc -Wall happy	28 years ago
Guido van Rossum	8f74571596	Use a faster way to check for null bytes in the string argument for int(), long(), float().	28 years ago
Guido van Rossum	d6af46d4ae	Need a cast when comparing type object in isinstance()	29 years ago
Guido van Rossum	f5dd914196	Support type objects in isinstance(). E.g. isinstance('',types.StringType) will return true now instead of raising a TypeError exception. This is for JPython compatibility.	29 years ago
Guido van Rossum	ee81af8977	Release interpreter lock around readline call in [raw_]input().	29 years ago
Barry Warsaw	b01a7fa5f8	initerrors(): Eliminate circular reference which was causing a small but annoying memory leak. This was introduced when PyExc_Exception was added; the loop above populating the PyExc_StandardError exception tuple started at index 1 in bltin_exc, but PyExc_Exception was added at index 0, so PyExc_StandardError was getting inserted in itself! How else can a tuple include itself?! Change the loop to start at index 2. This was a fun one! :-)	29 years ago
Barry Warsaw	412cdc2284	[Py_Exc]NumberError => [Py_Exc]ArithmeticError	29 years ago
Guido van Rossum	0474832d9c	Introduce PyExc_Exception as the conceptual root class for all exceptions.	29 years ago
Guido van Rossum	aee0bad0a5	First part of package support. This doesn't yet support "import a.b.c" or "from a.b.c import x", but it does recognize directories. When importing a directory, it initializes __path__ to a list containing the directory name, and loads the __init__ module if found. The (internal) find_module() and load_module() functions are restructured so that they both also handle built-in and frozen modules and Mac resources (and directories of course). The imp module's find_module() and (new) load_module() also have this functionality. Moreover, imp unconditionally defines constants for all module types, and has two more new functions: find_module_in_package() and find_module_in_directory(). There's also a new API function, PyImport_ImportModuleEx(), which takes all four __import__ arguments (name, globals, locals, fromlist). The last three may be NULL. This is currently the same as PyImport_ImportModule() but in the future it will be able to do relative dotted-path imports. Other changes: - bltinmodule.c: in __import__, call PyImport_ImportModuleEx(). - ceval.c: always pass the fromlist to __import__, even if it is a C function, so PyImport_ImportModuleEx() is useful. - getmtime.c: the function has a second argument, the FILE*, on which it applies fstat(). According to Sjoerd this is much faster. The first (pathname) argument is ignored, but remains for backward compatibility (so the Mac version still works without changes). By cleverly combining the new imp functionality, the full support for dotted names in Python (mini.py, not checked in) is now about 7K, lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly commented). Good night!	29 years ago
Barry Warsaw	757af0e7bb	Removed obsolete exception PyExc_AccessError. Added PyErr_MemoryErrorInst to hold the pre-instantiated instance when using class based exceptions. Simplified the creation of all built-in exceptions, both class based and string based. Actually, for class based exceptions, the string ones are still created just in case there's a problem creating the class based ones (so you still get some exception handling!). Now the init and fini functions run through a list of structure elements, creating the strings (and optionally classes) for every entry. initerrors(): the new base class exceptions StandardError, LookupError, and NumberError are initialized when using string exceptions, to tuples containing the list of derived string exceptions. This GvR trick enables forward compatibility! One bit of nastiness is that the C code has to know the inheritance tree embodied in exceptions.py. Added the two phase init and fini functions.	29 years ago
Barry Warsaw	cde8b1ba0c	Two new built-in functions: issubclass() and isinstance(). Both take classes as their second arguments. The former takes a class as the first argument and returns true iff first is second, or is a subclass of second. The latter takes any object as the first argument and returns true iff first is an instance of the second, or any subclass of second. Also, change all occurances of pointer compares against PyExc_IndexError with PyErr_ExceptionMatches() calls.	29 years ago
Guido van Rossum	25ce566661	The last of the mass checkins for separate (sub)interpreters. Everything should now work again. See the comments for the .h files mass checkin (e.g. pystate.h) for more detail.	29 years ago

Guido van Rossum	b05a5c7698	Instead of importing graminit.h whenever one of the three grammar 'root' symbols is needed, define these in Python.h with a Py_ prefix.	29 years ago
Guido van Rossum	666b17a280	New dir() function -- - uses abstract interface where possible - uses __members__ and __methods__ - returns [] when an object has no info available	29 years ago

Guido van Rossum	79f25d9a7b	Quickly renamed the remaining files -- this directory is done.	29 years ago
Guido van Rossum	6bf62dad9e	Keep gcc -Wall and Microsoft VC happy.	29 years ago
Guido van Rossum	c6472e9ee1	1. Add string conversions to int(), long(), float(). (Not to complex()!) 2. Fix two bugs in complex(): - Memory leak when using complex(classinstance) -- r was never DECREF'ed. - Conversion of the second argument, if not complex, was done using the type vector of the 1st.	29 years ago
Guido van Rossum	1c6a459921	Define __debug__ as 0 if -O is given, 1 otherwise. Also test for errors in initializing the dictionary.	29 years ago

Guido van Rossum	d266eb460e	New permission notice, includes CNRI.	30 years ago
Guido van Rossum	b75fba04c7	Forget about Ellipses b/w compatibility.	30 years ago
Guido van Rossum	e449af7da9	Ellipses -> Ellipsis rename (the dictionary really says that it should be Ellipsis!). Bumped the API version because a linker-visible symbol is affected. Old C code will still compile -- there's a b/w compat macro. Similarly, old Python code will still run, builtin exports both Ellipses and Ellipsis.	30 years ago
