Definition : Class is a collection of variables and methods into a single unit. Program 1 : class Student(): def display(self): print(“Simple Student”) s=Student() s.display() #Student().display() Program 2 : class Student(): def display(self,a,b): print(“sum”,(a+b)) s=Student() s.display(10,20) #Student().display(10,20) All the functions of a class will have one parameter at least that …
Definition : Set is a function which is meant for eliminating duplicate values available in a list or tuple. Program 1 : Data=[‘a’,’b’,’c’,’e’,’f’,’g’,’a’,’b’] Data1=[‘a’,’b’,’c’,’e’,’f’] Print(data) Print(set(data)) Print(set(data).difference(set(data1)) Print(set(data).intersection(set(data1))) Print(set(data).union(set(data1))) Program 2 : Data=[‘a’,’b’,’c’,’e’,’f’,’g’,’a’,’b’] Data1=set(data) Data1.add(“h”) Print(data1) data1.add(“I”) Print(data1) data1.add(“j”) Print(data1) data1.remove(“h”) Print(data1)
Definition : Dictionary is a data representation which is meant for holding the data in linear manner. Dictionary is basically use for representing key and value representations in python program. Program 1 : Student={‘name’ : ‘test’,’age’ : 22, ‘fee’ : 17.6} Print(student) Print(student[‘age], student[‘name’]) If we want name=test age=22 …
Definition : this is a linear data structure which is meant for holding the data in linear manner. Tuple will not allow any element modification during the program. Tuple is not allow to store the values Program : a=(‘a’,’b’,’c’,’d’,’e’) b=(1,2,3,4,5,6,7,8) c=”h”,”e”,”l”,”l”,”o” Print(a) Print(b) Print(c)
Definition : List is a linear data structure which is meant for holding the data in linear manner. Program 1 : a=[99,2,3,4,5,6,7,8,’a’,’b’,’c’,’d’,’e’] Print(a[1]) Print(a[-1]) Print(a[-2]) Program 2 : A=[‘a’,’b’,’c’,’d’,’e’,1,2,3,4,5,6,7,8] B=[1,2,3,4,5,6,7,8] Print(a) Print(b*3) Print(b[4]) Print(len(b)) Program 3 : b=[1,2,3,4,5,6,7,8] b[5]=10 Print(b) b.insert(6,99) print(b) b.remove(10) print(b) program 4 : b=[1,2,3,4,5,6,7,8] for …
