poll([timeout]) Return whether there is any data available to be read. If timeout is not specified then it will return immediately. If timeout is a number then this specifies the maximum time in seconds to block. If timeout is None then an infinite timeout is used. Note that multiple connection objects may be polled at once by using multiprocessing.connection.wait().

ord(c) Given a string representing one Unicode character, return an integer representing the Unicode code point of that character. For example, ord('a') returns the integer 97 and ord('€') (Euro sign) returns 8364. This is the inverse of chr().

math.factorial(x) Return x factorial. Raises ValueError if x is not integral or is negative.

testsRun The total number of tests run so far.

typing.cast(typ, val) Cast a value to a type. This returns the value unchanged. To the type checker this signals that the return value has the designated type, but at runtime we intentionally don’t check anything (we want this to be as fast as possible).

rfile Contains an input stream, positioned at the start of the optional input data.

version Variable that specifies the user agent of the opener object. To get urllib to tell servers that it is a particular user agent, set this in a subclass as a class variable or in the constructor before calling the base constructor.

colorsys.yiq_to_rgb(y, i, q) Convert the color from YIQ coordinates to RGB coordinates.

audioop.lin2alaw(fragment, width) Convert samples in the audio fragment to a-LAW encoding and return this as a bytes object. a-LAW is an audio encoding format whereby you get a dynamic range of about 13 bits using only 8 bit samples. It is used by the Sun audio hardware, among others.

stringprep.in_table_d1(code) Determine whether code is in tableD.1 (Characters with bidirectional property “R” or “AL”).
