	"""Gets the most current market data on the price of a symbol.

	Args:
		symbols:

			string or list of strings, each string a symbol to be queried.
			Notice symbols=['spy'], symbols='spy both work

		fields:

			string or list of strings, each string a field to be grabbed.
			By default, get all fields

		dataframe:

			flag, specifies whether to return data in pandas dataframe
			or flat list of dictionaries.

		block:
			Specify whether to block thread if request exceeds rate limit

	Returns:
		Depends on dataframe flag. Will return pandas dataframe, or possibly
		list of dictionaries, each one a single quote.

	Raises:
		RateLimitException: If block=False, rate limit problems will be raised

	Examples:

.. code-block:: python

	# Get the quotes in dataframe format
	#  Each row will only have elements bid, ask, and last
	quotes = a.quote(
		symbols=['spy','gLD','F','Ibm'], # not case sensitive
		fields=['bid','ask,'last'],

	# Access a specific symbol by the dataframe
	print(quotes.loc['SPY'])



.. code-block:: python

	# Get the quotes in dataframe format
	quotes = a.quote(
		'AAPL',
		dataframe=False

	# Access a specific symbol in the dict
