+* 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
