We have learned about list in previous blogs, list can contain dictionary object vice versa. Both has the ability to change their size at run time. list and dictionary can grow and shrink according to elements at run time. But what is the actual difference b/w these two? Read below.  One is that elements from list object contains elements in linear manner but the dictionary object contains elements as key and value pair.   Elements from list object are fetched with element's location but in dictionary the elements is fetched with key. Last but not the least that list is an ordered object means when the list object is printed it shows the elements as these were inserted but dictionary sort the keys and print the values.      Examples:-  1 2 3 dict_ = dict () dict_ = { "Python" : "Hunter" , "Is" : "Better" } print (dict_) There are lot of methods to manipulate the dictionary object but some of the met...

Slicing is a technique in python to pick up data from list,tuple and set from desired location. lets make python a bit more beautiful with slicing technique.  Caution :- No animal is hurt during the development of this tutorial :)   it can be done with three arguments.  e.g dataString [ begin : end : step ] argument begin and end are giving lucid  view, these arguments are to instruct the script that from where the slicing will begin and where it will end, but the tricky argument is the last one ( " step ") . it indicates that how many  index or indices  the code have to   hops or skip to pick up the next slice. In the below example the slicing is starting form 6th index or indices and go till 21th  index and after every slice it will skip the 3 index or indices between the begin and end index.  let's take an example :- 1 25 str = "1abcdefghijklmnopqrstuvwxyz" print ( str [ 6 : 21 : 3 ]) list_1 = [ "T...

Tuple is like list but unlike in structure and functionality. first basic difference is can be figured out by the structure. List elements are enclosed with '[]' brackets but tuple elements are enclosed with '()' parentheses. Few properties of tuple:- 1. It is faster than list. 2. Unlike list, tuple is immutable, i.e. tuple's data cannot be changed once created, we should use tuple if we want our data to be safe from accidental change.  As you can see in title picture, you are allowed to see but cannot touch it. 3. We can use tuple as key in dictionaries   whereas this is not the case with list,  we can’t use list as key in dictionary <Link this post (dictionary) will be available on 16 March 2018>.      Examples:-  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 myTuple= tuple ( 'Python' ) # it takes only one parameter print (myTuple) #it will break down each character into separate elements, just l...
