    32 * Outline

    33   - What is meant by parsing data? 

    34   - String operations required for parsing

    35   - Converting between data-types. 

    36 * Question 1

    37   Split the variable line using a space as argument. Is it same as

    38   splitting without an argument ?

    39 * Solution 1

    40   We see that when we split on space, multiple whitespaces are not

    41   clubbed as one and there is an empty string everytime there are two

    42   consecutive spaces.

    43 * Question 2

    44   What happens to the white space inside the sentence when it is

    45   stripped? 

    46 * Solution 2

    47   #+begin_src python

    48     In []: a_str = "     white      space     "

    49     In []: a_str.strip()

    50   #+end_src

    51 * Question 3

    52   What happens if you do =int("1.25")=

    53 * Solution 3

    54   It raises an error since converting a float string into integer

    55   directly is not possible. It involves an intermediate step of

    56   converting to float.

    57   #+begin_src python

    58     In []: dcml_str = "1.25"

    59     In []: flt = float(dcml_str)

    60     In []: flt

    61     In []: number = int(flt)

    62     In []: number

    63   #+end_src

    64 * Summary

    65   + How to tokenize a string using various delimiters

    66   + How to get rid of extra white space around

    67   + How to convert from one type to another

    68   + How to parse input data and perform computations on it

    69 * Thank you!
