Introduction to Python

Python is a high level, object oriented programming language. It has simple and easy to learn syntax. It is good for beginners as well as for developers. Python is used in various fields now with its growth in popularity as compared to other Programming languages like Java, C, PHP, etc. Python was developed by Guido Van Rossum in February 1991 . Python was supposed to be a successor of the ABC language. Python programming language was named after the famous BBC Comedy show, Monty Python's Flying Circus.

Programming Questions

Programming Questions with source code Program 1: Program to obtain side of a square and then calculate its area.   Input code:  a=int(input("Enter the side of square:")) sq=a**2 print("Area of square is :",sq) Program 2: Program to obtain length and breadth of a rectangle and calculate its area. Input Code:   l=int(input("Enter length of the rectangle:")) b=int(input ("Enter breadth of the rectangle:")) area=l*b print("Area of rectangle is:",area) Program 3: Program to obtain height and base of a triangle and calculate its area.   Input Code: l=int(input("Enter length of triangle")) b=int(input("Enter base of triangle")) area=0.5*b*h print("Area of triangle is:",area) Program 4: Program to obtain a number and print its square and cube. Input Code:   num=float(input("Enter the number:")) sq=num*num cube=num*num*num print("Square of",num,"is",sq) print("Cube of",num,&q

Variables & Type of Literals and Operators

Variables in Python Variables are the character(s) used to store a value to be used further in the program. For example, when you want to store roll number of a student in the program then we use some variables to store roll number data:                      Roll_no = 35 In the above statement we use an identifier(Roll_no) to store roll number of a student of integer type. Then we can call Roll_no a numeric variable.                      Em_name = “Sanu” Then we can call Em_name a string variable.   IMPORTANT: In Python, you cannot use integer, float, complex number, expression as a variable as it will raise an error. You can only use characters, or identifiers to store any value. For example: 36=Id 25=x 2a/c=20     In Python, you can use multiple assignments.  #that’s nice For example: A,B,C=5,10,15 x=y=z=50   Dynamic Typing A variable who is used to store a value of one type, can be used again to store a value of different type. Python uses D
