Program-6: Example of Multi Line Comments and Various ways of Assignments

'''

Example of Multi Line Comments. In Python using three times single quotes will create the Multi Line comment. It is used for detailed additional information related tot he program. It helps to clarify the important things '''

#Multiple Ways for Assignment

# 1. Assigning Same value to multiple variables.

x = y = z = 500

print("X = ",x,": Y = ",y,": Z = ",z)

# 2. Assigning Multiple Values in Multiple Variables.

x,y,z = 100, 200, 300

print("X = ",x,": Y = ",y,": Z = ",z)

#3. Swapping of values of variables

print("Swapping of values of variables")

x, y = y, x

print("X = ",x,": Y = ",y)

Program-7: Example of Variable Declarations in Python.

# Variable Definition

num  = 150              # An integer assignment

mtrs = 15000.0          # A floating point

name = "Wilson Alfred"  # A string

print(num)

print(mtrs)

print(name)

print()

                        #Multiple Assignment

n, r, s = 10, 25.5, "Hello Python"

print(n)               # An integer number

print(r)               # A floating number

print(s)               # A String
