Dictionary is an unorederd collection of data values that store key : value using instead of a single value. For example, Key is unchangeable data type and value, you give some value to the key. That is changeable. You may give a keys are alphabets or numbers which you want. For example, dictionary = { 1 : "apple", 2 : "orange", 3 : "guava" } Other example, Student = { Name : "Ravi", Class : "7" } Here, student is a dictionary name and Name is a key Ravi is a value. You can change Ravi and 7 instead of using other values. But u can't change Name and Class. Once u use the key is unchangeable. And the first example 1,2,3 are keys and apple,orange,guave are vaues. I hope u understand.
