PDF reordering script

This script can be helpful for re-arranging a pdf file which may have pages out of order.

About the script ReArrange.py**

It takes path of the file as an Input.
Then it takes current page which is in the wrong order and the right page no. it should be on.
Seperate values by a comma ',' and line by line.
- Example:-
  
  1,2
  3,1
  2,3
  
  here the 1st page in the pdf should be on the 2nd page instead and so on.
The script parses and sorts the input values by the function input_and_parse(n) which takes no. of pages in pdf file as input.
Then using the re_arrange() function we can get the desired file after rearranging.
