Easy as falling off a log. You can't write "var1", "var2" etc. but you 
can write it as "var[0]", "var[1]" etc.

var = ['banana', 'apple',  'mango'] 
print var[0]  # prints 'banana'
print var[1]  # prints 'apple'
print var[2]  # prints 'mango'



Of course "var" is not a very good variable name. "fruit" or "fruits" 
would be better.
