contextmanager.__exit__(exc_type, exc_val, exc_tb) Exit the runtime context and return a Boolean flag indicating if any exception that occurred should be suppressed. If an exception occurred while executing the body of the with statement, the arguments contain the exception type, value and traceback information. Otherwise, all three arguments are None. Returning a true value from this method will cause the with statement to suppress the exception and continue execution with the statement imm

CookiePolicy.domain_return_ok(domain, request) Return false if cookies should not be returned, given cookie domain. This method is an optimization. It removes the need for checking every cookie with a particular domain (which might involve reading many files). Returning true from domain_return_ok() and path_return_ok() leaves all the work to return_ok(). If domain_return_ok() returns true for the cookie domain, path_return_ok() is called for the cookie path. Otherwise, path_return_ok() and r

gettext.ngettext(singular, plural, n) Like gettext(), but consider plural forms. If a translation is found, apply the plural formula to n, and return the resulting message (some languages have more than two plural forms). If no translation is found, return singular if n is 1; return plural otherwise. The Plural formula is taken from the catalog header. It is a C or Python expression that has a free variable n; the expression evaluates to the index of the plural in the catalog. See the GNU ge

class smtplib.SMTP(host='', port=0, local_hostname=None, [timeout, ]source_address=None) An SMTP instance encapsulates an SMTP connection. It has methods that support a full repertoire of SMTP and ESMTP operations. If the optional host and port parameters are given, the SMTP connect() method is called with those parameters during initialization. If specified, local_hostname is used as the FQDN of the local host in the HELO/EHLO command. Otherwise, the local hostname is found using socket.get

abstractmethod find_module(fullname, path=None) An abstact method for finding a loader for the specified module. Originally specified in PEP 302, this method was meant for use in sys.meta_path and in the path-based import subsystem. Changed in version 3.4: Returns None when called instead of raising NotImplementedError.

get_value(key, args, kwargs) Retrieve a given field value. The key argument will be either an integer or a string. If it is an integer, it represents the index of the positional argument in args; if it is a string, then it represents a named argument in kwargs. The args parameter is set to the list of positional arguments to vformat(), and the kwargs parameter is set to the dictionary of keyword arguments. For compound field names, these functions are only called for the first component of t

Dialect.lineterminator The string used to terminate lines produced by the writer. It defaults to '\r\n'. Note The reader is hard-coded to recognise either '\r' or '\n' as end-of-line, and ignores lineterminator. This behavior may change in the future.

difflib.ndiff(a, b, linejunk=None, charjunk=IS_CHARACTER_JUNK) Compare a and b (lists of strings); return a Differ-style delta (a generator generating the delta lines). Optional keyword parameters linejunk and charjunk are filtering functions (or None): linejunk: A function that accepts a single string argument, and returns true if the string is junk, or false if not. The default is None. There is also a module-level function IS_LINE_JUNK(), which filters out lines without visible characters

bytes.splitlines(keepends=False) bytearray.splitlines(keepends=False) Return a list of the lines in the binary sequence, breaking at ASCII line boundaries. This method uses the universal newlines approach to splitting lines. Line breaks are not included in the resulting list unless keepends is given and true. For example: >>> b'ab c\n\nde fg\rkl\r\n'.splitlines() [b'ab c', b'', b'de fg', b'kl'] >>> b'ab c\n\nde fg\rkl\r\n'.splitlines(keepends=True) [b'ab c\n', b'\n', b'de fg
