* 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

* 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!
