5. File Handling
1. Creating copy of a file.
2. Write a function that takes three argument 1st input file, 2nd output file and 3rd transformation function. First argument is the file opened for reading, second argument is the file opened for writing
   and third argument is a function, which takes single string and performs a transformation of your choice and returns the transformed string. The function should reed each line in the input file, pass
   the line through transformation function and then write transformed line to output file. A transformation can be - capitalize first alphabet of every word.
3. Write a function to create a text file containing following data
   Neither apple nor pine are in pineapple. Boxing rings are square.
   Writers write, but fingers don't fing. Overlook and oversee are opposites. A house can burn up as it burns down. An alarm goes off by going on.
   i) Read back the entire file content using read() or readlines () and display on screen.
   ii) Append more text of your choice in the file and display the content of file with line numbers
   prefixed to line.
   iii) Display last line of file.
   iv) Display first line from 10th character onwards
   v) Read and display a line from the file. Ask user to provide the line number to be read.
4. Create a dictionary having decimal equivalent of roman numerals. Store it in a binary file. Write a function to convert roman number to decimal equivalent using the binary file data.
5. Write a program to delete the content provided by user from the binary file. The file is very large and can't fit in computers memory.
6. Write a program to read a file 'Story.txt' and create another file, storing an index of Story.txt telling which line of the file each word appears in. If word appears more than once, then index should show all the line numbers containing the word.
   Hint : Dictionary with key as word(s) can be used to solve this.
7. Write a function called replace file(), that takes pattern string, replacement string and two file names as argument. The function should read the first file and write the content into second file (creating it, if necessary). If the pattern string appear anywhere in first file, it should be replaced by replacement string in second file.
8. Write a program to accept a filename from the user and display all the lines from the file which contain python comment character '#'.
9. Reading a file line by line from beginning is a common task, what if you want to read a file backward. This happens when you need to read log files. Write a program to read and display content of file from end to beginning.
10. Create a class item to store information of different items, existing in a shop. At least following is to be stored w.r.t. each item code, name, price, qty. Write a program to accept the data from user and store it permanently in the file. Also provide user with facility of searching and updating the data in file based on code of item.
