sys.base_prefix Set during Python startup, before site.py is run, to the same value as prefix. If not running in a virtual environment, the values will stay the same; if site.py finds that a virtual environment is in use, the values of prefix and exec_prefix will be changed to point to the virtual environment, whereas base_prefix and base_exec_prefix will remain pointing to the base Python installation (the one which the virtual environment was created from). New in version 3.3.

xmlparser.ErrorByteIndex Byte index at which an error occurred.

Wave_read.getsampwidth() Returns sample width in bytes.

operator.itruediv(a, b) operator.__itruediv__(a, b) a = itruediv(a, b) is equivalent to a /= b.

sys._debugmallocstats() Print low-level information to stderr about the state of CPython’s memory allocator. If Python is configured –with-pydebug, it also performs some expensive internal consistency checks. New in version 3.3. CPython implementation detail: This function is specific to CPython. The exact output format is not defined here, and may change.

flush([offset[, size]]) Flushes changes made to the in-memory copy of a file back to disk. Without use of this call there is no guarantee that changes are written back before the object is destroyed. If offset and size are specified, only changes to the given range of bytes will be flushed to disk; otherwise, the whole extent of the mapping is flushed. (Windows version) A nonzero value returned indicates success; zero indicates failure. (Unix version) A zero value is returned to indicate suc
