index(x[, start[, stop]]) Return the position of x in the deque (at or after index start and before index stop). Returns the first match or raises ValueError if not found. New in version 3.5.

os.ctermid() Return the filename corresponding to the controlling terminal of the process. Availability: Unix.

newlines A string, a tuple of strings, or None, indicating the newlines translated so far. Depending on the implementation and the initial constructor flags, this may not be available.

columns Width of the terminal window in characters.

readline.get_completion_type() Get the type of completion being attempted. This returns the rl_completion_type variable in the underlying library as an integer.

audioop.findmax(fragment, length) Search fragment for a slice of length length samples (not bytes!) with maximum energy, i.e., return i for which rms(fragment[i*2:(i+length)*2]) is maximal. The fragments should both contain 2-byte samples. The routine takes time proportional to len(fragment).

__round__() __round__(ndigits) The first version returns the nearest int to self, rounding half to even. The second version rounds self to the nearest multiple of Fraction(1, 10**ndigits) (logically, if ndigits is negative), again rounding half toward even. This method can also be accessed through the round() function.

Path.is_char_device() Return True if the path points to a character device (or a symbolic link pointing to a character device), False if it points to another kind of file. False is also returned if the path doesn’t exist or is a broken symlink; other errors (such as permission errors) are propagated.

total_changes Returns the total number of database rows that have been modified, inserted, or deleted since the database connection was opened.

next_minus(context=None) Return the largest number representable in the given context (or in the current thread’s context if no context is given) that is smaller than the given operand.
