write(data) Write some data bytes to the transport. This method does not block; it buffers the data and arranges for it to be sent out asynchronously.

size_diff Difference of total size of memory blocks in bytes between the old and the new snapshots (int): 0 if the memory blocks have been allocated in the new snapshot.

with_netmask A string representation of the network, with the mask in net mask notation.

coroutine read(n=-1) Read up to n bytes. If n is not provided, or set to -1, read until EOF and return all read bytes. If the EOF was received and the internal buffer is empty, return an empty bytes object. This method is a coroutine.

DefaultCookiePolicy.strict_rfc2965_unverifiable Follow RFC 2965 rules on unverifiable transactions (usually, an unverifiable transaction is one resulting from a redirect or a request for an image hosted on another site). If this is false, cookies are never blocked on the basis of verifiability

class turtle.RawPen(canvas) Parameters: canvas – a tkinter.Canvas, a ScrolledCanvas or a TurtleScreen Create a turtle. The turtle has all methods described above as “methods of Turtle/RawTurtle”.

__contains__(name) Return true if the message object has a field named name. Matching is done case-insensitively and name should not include the trailing colon. Used for the in operator, e.g.: if 'message-id' in myMessage: print('Message-ID:', myMessage['message-id'])

len(s) Return the length (the number of items) of an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary, set, or frozen set).

random.uniform(a, b) Return a random floating point number N such that a <= N <= b for a <= b and b <= N <= a for b < a. The end-point value b may or may not be included in the range depending on floating-point rounding in the equation a + (b-a) * random().

bytearray.startswith(prefix[, start[, end]]) Return True if the binary data starts with the specified prefix, otherwise return False. prefix can also be a tuple of prefixes to look for. With optional start, test beginning at that position. With optional end, stop comparing at that position. The prefix(es) to search for may be any bytes-like object.
