It helps to store numeric values.Changing the values of number data type leads to the formation of new objects.
Strings are created just by enclosing characters within the quotes. Quotes can be single or double quotes.The starting and ending of quotes should be same for representing a character.
List can be written in the form of sequence of values which is separated by commas within square brackets.A special feature about list in python is that,values specified need not be of same time.
In python tuples can be defines as a sequence of constant objects.They are same as list but the difference is that list can be changed but tuples can't and list uses square brackets while the tuples are provided within parenthesis.
