Objectives

1.State differences between Python 2 and Python 3 version.

2.Input the string “Python” as a list of characters from the console, delete at least 2 characters, reverse the resultant string and print it.

• Sample input:python

• Sample output:ntyp

Take two numbers from the user and perform arithmetic operations on them.

3.Write a program that accepts a sentence and replace each occurrence of ‘python’ with ‘pythons’ without using regex.

• Sample input:I love playing with python

• Sample output:I love playing with pythons

Differences between python 2 and 3

Python2

1. Started in mid 2010

2. Integer division 5/2=2

3. Print statement ex: print "hello"

4. It uses xrange and range functions

5. Here raw_input returns a string and input() tries to run the input as a python expression

Python3

1. Started in early 2014

2. Integer division 5/2=2.5

3. Print statement ex: print ("hello")

4. It has no xrange function

5. Here input() returns a string always

Deleting at least 2 chars and Reverse the string

CODE

• Reverse string function is called
• Input is taken from the console
• last and last but second chars are removed (remove function is called)
• Reverse the string by calling reverse function

Output

Arithmetic Operations

Code

• Take 2 numbers from the console
• Call the arithmetic operation functions i.e add, subtract, multiply, divide

Output:

Replacing python with pythons

Code:

• Take the string from the console
• convert into lower case
• Replace the "python" with "pythons" by using replace method

Output:
