   Python	Kaila Letteri	Functions	Bring your specific questions, rather than topics, please Differences between list and dictionary List: the order of elements is important Dictionary: the order of elements does not matter List: an element can be accessed by index Dictionary: an element (value) can be accessed by key List: multiple element (element range) can be accessed by index range Dictionary: one element at a time to access An element of a dictionary can be a list, and an element of a list can be a dictionary. See the screenshot below. Difference between two functions, split() and join() split() is associated with a string. "Mercy is the best".split() join() is associated with a string. ''.join() split() takes a string and returns a list. "Mercy is the best".split('z') 'z' is a delimiter join() takes an iterable (for example, a list) and returns a string. '+'.join(['1','4', '3','7']) returns '1+4+3+7' split() and join() are performing an opposite manipulation of strings.	Dobbs Ferry, Maher Hall 112	2pm - 3:30pm

   Python	Nick Franzi	split()	The function split() can be applied to a string split() takes an argument, based on which you want to split split() returns a list of all strings split "Mercy Cyber is the best".split() returns what? ['Mercy', 'Cyber', 'is', 'the', 'best'] Since no argement is used for split(), the given string is split based on a space. Based on a space? or multiple spaces as well? Yes, any number of consecutive spaces! what about split(':')? for any number of ':'? No, for any characters but white spaces, each such character can be applied. try if you want!
