wait_for(predicate, timeout=None) Wait until a condition evaluates to True. predicate should be a callable which result will be interpreted as a boolean value. A timeout may be provided giving the maximum time to wait. This utility method may call wait() repeatedly until the predicate is satisfied, or until a timeout occurs. The return value is the last return value of the predicate and will evaluate to False if the method timed out. Ignoring the timeout feature, calling this method is rough

heading(column, option=None, **kw) Query or modify the heading options for the specified column. If kw is not given, returns a dict of the heading option values. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values. The valid options/values are: text: text The text to display in the column heading. image: imageName Specifies an image to display to the right of the column heading. anchor: anchor Specifies how the

class html.parser.HTMLParser(*, convert_charrefs=True) Create a parser instance able to parse invalid markup. If convert_charrefs is True (the default), all character references (except the ones in script/style elements) are automatically converted to the corresponding Unicode characters. An HTMLParser instance is fed HTML data and calls handler methods when start tags, end tags, text, comments, and other markup elements are encountered. The user should subclass HTMLParser and override its m

class subprocess.CompletedProcess The return value from run(), representing a process that has finished. args The arguments used to launch the process. This may be a list or a string. returncode Exit status of the child process. Typically, an exit status of 0 indicates that it ran successfully. A negative value -N indicates that the child was terminated by signal N (POSIX only). stdout Captured stdout from the child process. A bytes sequence, or a string if run() was called wi

detach() Separate the underlying binary buffer from the TextIOBase and return it. After the underlying buffer has been detached, the TextIOBase is in an unusable state. Some TextIOBase implementations, like StringIO, may not have the concept of an underlying buffer and calling this method will raise UnsupportedOperation. New in version 3.1.

pkgutil.iter_modules(path=None, prefix='') Yields (module_finder, name, ispkg) for all submodules on path, or, if path is None, all top-level modules on sys.path. path should be either None or a list of paths to look for modules in. prefix is a string to output on the front of every module name on output. Note Only works for a finder which defines an iter_modules() method. This interface is non-standard, so the module also provides implementations for importlib.machinery.FileFinder and zipi

itertools.takewhile(predicate, iterable) Make an iterator that returns elements from the iterable as long as the predicate is true. Roughly equivalent to: def takewhile(predicate, iterable): # takewhile(lambda x: x<5, [1,4,6,4,1]) --> 1 4 for x in iterable: if predicate(x): yield x else: break

winreg.EnumValue(key, index) Enumerates values of an open registry key, returning a tuple. key is an already open key, or one of the predefined HKEY_* constants. index is an integer that identifies the index of the value to retrieve. The function retrieves the name of one subkey each time it is called. It is typically called repeatedly, until an OSError exception is raised, indicating no more values. The result is a tuple of 3 items: Index Meaning 0 A string that identifies the value name 1

set_seqs(a, b) Set the two sequences to be compared.

IMAP4.starttls(ssl_context=None) Send a STARTTLS command. The ssl_context argument is optional and should be a ssl.SSLContext object. This will enable encryption on the IMAP connection. Please read Security considerations for best practices. New in version 3.2. Changed in version 3.4: The method now supports hostname check with ssl.SSLContext.check_hostname and Server Name Indication (see ssl.HAS_SNI).
