* Outline 

** Datatypes in Python

*** Numbers

*** Boolean

*** Sequence

** Operators in Python

*** Arithmetic Operators

*** Boolean Operators

** Python Sequence Datatypes

*** list

*** string

*** tuple

* Numbers

  - int

  - float

  - complex

* Question 1

   - Find the absolute value of 3+4j 

* Solution 1

  #+begin_src python

    abs(3+4j)

  #+end_src python

* Question 2

  - What is the datatype of number 999999999999999999? Is it

not int?

* Solution 2

  - Long

  - Large integers numbers are internally stored in python as Long

    datatype.

* Boolean

  #+begin_src python

    In []: t=True

    In []: f=False

  #+end_src

* Question 3

  - Using python find sqaure root of 3?

* Solution 3

  - 3**0.5

* Question 4

  - Is 3**1/2 and 3**0.5 same

* Solution 4

  - No,One gives an int answer and the other float        

* Sequence Data types

** Properties

 - Data in Sequence 

 - Accessed using Index

** Type

 - list

 - String

 - Tuple

* All are Strings

   #+begin_src python 

      k = 'Single quote'

      l = "Double quote contain's single quote"

      m = '''"Contain's both"'''

    #+end_src 

* Immutabilty Error

   #+begin_src python

      In []: greeting_string[1]='k'

      -------------------------------------------------------

      TypeError           Traceback (most recent call last)

      /home/fossee/<ipython console> in <module>()

      TypeError: 'str' object does not support item assignment

   #+end_src 

* Question 5

  Check if 3 is an element of the list [1,7,5,3,4]. In case it is

change it to 21.

* Solution 5

     #+begin_src python

        l=[1,7,5,3,4]

        3 in l

        l[3]=21

        l

     #+end_src

* Question 6

  Convert the string ~"Elizabeth is queen of england"~ to ~"Elizabeth is

queen"~

* Solution 6

     #+begin_src python

    s = "Elizabeth is queen of england"                                                                                                                 

    stemp = s.split()                                                                                                                                   

    ' '.join(stemp[:3])                                                                                                                               

    #+end_src 

* Summary 

  - Number Datatypes -- integer,float and complex 

  - Boolean and datatype and operators

  - Sequence data types -- List, String and Tuple

  - Accesing sequence

  - Slicing sequences

  - Finding length, sorting and reversing operations on sequences

  - Immutability
