* Outline
  - What is meant by parsing data? 
  - String operations required for parsing
  - Converting between data-types. 
* Question 1
  Split the variable line using a space as argument. Is it same as
  splitting without an argument ?
* Solution 1
  We see that when we split on space, multiple whitespaces are not
  clubbed as one and there is an empty string everytime there are two
  consecutive spaces.
* Question 2
  What happens to the white space inside the sentence when it is
  stripped? 
* Solution 2
  #+begin_src python
    In []: a_str = "     white      space     "
    In []: a_str.strip()
  #+end_src
* Question 3
  What happens if you do =int("1.25")=
* Solution 3
  It raises an error since converting a float string into integer
  directly is not possible. It involves an intermediate step of
  converting to float.
  #+begin_src python
    In []: dcml_str = "1.25"
    In []: flt = float(dcml_str)
    In []: flt
    In []: number = int(flt)
    In []: number
  #+end_src
* Summary
  + How to tokenize a string using various delimiters
  + How to get rid of extra white space around
  + How to convert from one type to another
  + How to parse input data and perform computations on it
* Thank you!
