faulthandler.dump_traceback_later(timeout, repeat=False, file=sys.stderr, exit=False) Dump the tracebacks of all threads, after a timeout of timeout seconds, or every timeout seconds if repeat is True. If exit is True, call _exit() with status=1 after dumping the tracebacks. (Note _exit() exits the process immediately, which means it doesn’t do any cleanup like flushing file buffers.) If the function is called twice, the new call replaces previous parameters and resets the timeout. The timer

class uuid.UUID(hex=None, bytes=None, bytes_le=None, fields=None, int=None, version=None) Create a UUID from either a string of 32 hexadecimal digits, a string of 16 bytes as the bytes argument, a string of 16 bytes in little-endian order as the bytes_le argument, a tuple of six integers (32-bit time_low, 16-bit time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bit clock_seq_low, 48-bit node) as the fields argument, or a single 128-bit integer as the int argument. When a string

set(item, column=None, value=None) With one argument, returns a dictionary of column/value pairs for the specified item. With two arguments, returns the current value of the specified column. With three arguments, sets the value of given column in given item to the specified value.

wave.openfp(file, mode) A synonym for open(), maintained for backwards compatibility.

POP3.capa() Query the server’s capabilities as specified in RFC 2449. Returns a dictionary in the form {'name': ['param'...]}. New in version 3.4.

email.utils.parsedate_to_datetime(date) The inverse of format_datetime(). Performs the same function as parsedate(), but on success returns a datetime. If the input date has a timezone of -0000, the datetime will be a naive datetime, and if the date is conforming to the RFCs it will represent a time in UTC but with no indication of the actual source timezone of the message the date comes from. If the input date has any other valid timezone offset, the datetime will be an aware datetime with

time.hour In range(24).

getboolean(section, option, *, raw=False, vars=None[, fallback]) A convenience method which coerces the option in the specified section to a Boolean value. Note that the accepted values for the option are '1', 'yes', 'true', and 'on', which cause this method to return True, and '0', 'no', 'false', and 'off', which cause it to return False. These string values are checked in a case-insensitive manner. Any other value will cause it to raise ValueError. See get() for explanation of raw, vars an

CookieJar.add_cookie_header(request) Add correct Cookie header to request. If policy allows (ie. the rfc2965 and hide_cookie2 attributes of the CookieJar‘s CookiePolicy instance are true and false respectively), the Cookie2 header is also added when appropriate. The request object (usually a urllib.request..Request instance) must support the methods get_full_url(), get_host(), get_type(), unverifiable(), has_header(), get_header(), header_items(), add_unredirected_header() and origin_req_hos
