Variable is a name of a memory loacation to store a value.
DeclarationWhen you assign a value to variable_name then automatically the memory is assigned for the variable.
var1=200 # int declaration var2=200.3 # floating point declaration var3="scanftree" # string declaration print var1 print var2 print var3
200 200.3 scanftree
Multiple Assignment:Python allows you to assign a single value to several variables simultaneously.
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
