  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING What Are Sequences? ➢ Sequences are containers with items that are accessible by indexing or slicing. ➢ The built-in len function takes any container as an argument and returns the number of items in the container. Sequence of Cars

Important thing about a list is that items in a list need not be of the same type.

  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Tuples
• 16.
  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Tuples ➢ A tuple is a sequence of immutable Python objects. ➢ Tuples are sequences, just like lists. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses. Fruits = ('Mango', 'Apple', 'Grapes‘) Tuple.index(elem)Index Tuple.count(elem)Count Tuple1+Tuple2Concatenation Tuple[range]Slicing Tuple * xRepetition

• 18.
  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Strings ➢ We can create them simply by enclosing characters in quotes. ➢ Python treats single quotes the same as double quotes. Fruits = 'Mango Apple Grapes' String[range] Updating Slicing Concatenation Reverse Repetition Membership String[range] + ‘x’ String 1 + String 2 String 1 * x In, not in String [:-1]

  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Sets
• 20.
  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Sets ➢ A set contains an unordered collection of unique and immutable objects. ➢ The set data type is, as the name implies, a Python implementation of the sets as they are known from mathematics. A BA B A B C (A C) / B (B C) / A C Fruits = {'Mango', 'Apple', 'Grapes‘} Slicing Add Element Clear Copy Difference Discard Remove Intersection

• 22.
  www.edureka.co/pythonEDUREKA PYTHON CERTIFICATIONTRAINING Dictionaries ➢ Dictionary is an unordered collection of key-value pairs. ➢ It is generally used when we have a huge amount of data. Example: Length del d [K] Membership Testing Key Value
