isatty() Return True if the stream is interactive (i.e., connected to a terminal/tty device).

class http.client.HTTPSConnection(host, port=None, key_file=None, cert_file=None, [timeout, ]source_address=None, *, context=None, check_hostname=None) A subclass of HTTPConnection that uses SSL for communication with secure servers. Default port is 443. If context is specified, it must be a ssl.SSLContext instance describing the various SSL options. key_file and cert_file are deprecated, please use ssl.SSLContext.load_cert_chain() instead, or let ssl.create_default_context() select the syst

class complex([real[, imag]]) Return a complex number with the value real + imag*1j or convert a string or number to a complex number. If the first parameter is a string, it will be interpreted as a complex number and the function must be called without a second parameter. The second parameter can never be a string. Each argument may be any numeric type (including complex). If imag is omitted, it defaults to zero and the constructor serves as a numeric conversion like int and float. If both

poll.poll([timeout]) Polls the set of registered file descriptors, and returns a possibly-empty list containing (fd, event) 2-tuples for the descriptors that have events or errors to report. fd is the file descriptor, and event is a bitmask with bits set for the reported events for that descriptor — POLLIN for waiting input, POLLOUT to indicate that the descriptor can be written to, and so forth. An empty list indicates that the call timed out and no file descriptors had any events to report

subdirs A dictionary mapping names in common_dirs to dircmp objects.

class types.MappingProxyType(mapping) Read-only proxy of a mapping. It provides a dynamic view on the mapping’s entries, which means that when the mapping changes, the view reflects these changes. New in version 3.3. key in proxy Return True if the underlying mapping has a key key, else False. proxy[key] Return the item of the underlying mapping with key key. Raises a KeyError if key is not in the underlying mapping. iter(proxy) Return an iterator over the keys of the underl

coroutine AbstractEventLoop.getaddrinfo(host, port, *, family=0, type=0, proto=0, flags=0) This method is a coroutine, similar to socket.getaddrinfo() function but non-blocking.

exception urllib.error.URLError The handlers raise this exception (or derived exceptions) when they run into a problem. It is a subclass of OSError. reason The reason for this error. It can be a message string or another exception instance. Changed in version 3.3: URLError has been made a subclass of OSError instead of IOError.

logging.basicConfig(**kwargs) Does basic configuration for the logging system by creating a StreamHandler with a default Formatter and adding it to the root logger. The functions debug(), info(), warning(), error() and critical() will call basicConfig() automatically if no handlers are defined for the root logger. This function does nothing if the root logger already has handlers configured for it. Note This function should be called from the main thread before other threads are started. In

bytes.rjust(width[, fillbyte]) bytearray.rjust(width[, fillbyte]) Return a copy of the object right justified in a sequence of length width. Padding is done using the specified fillbyte (default is an ASCII space). For bytes objects, the original sequence is returned if width is less than or equal to len(s). Note The bytearray version of this method does not operate in place - it always produces a new object, even if no changes were made.
