Python Variables:

Variable is a name of a memory loacation to store a value.



Declaration

When you assign a value to variable_name then automatically the memory is assigned for the variable.

Example


var1=200             # int declaration
var2=200.3           # floating point declaration
var3="scanftree"     # string declaration

print var1
print var2
print var3



Output

200
200.3
scanftree



Multiple Assignment:

Python allows you to assign a single value to several variables simultaneously.

Example:

a = b = c = 10                        # approach 1 
or
a, b, c =10, 20, "scanftree.com"      # approach 2 



In the first approach all variables a, b, c are assigned value 10
In the second approach a, b are assigned values 10 and 20 whereas c has been assigned with scanftree.com

var1=100
var2=30.3
var3="scanftree"

print var1
print var2
print var3
