7. b) File Handling (Problem)

Write a python program that reads 20 characters from a file and displays them?

Hint: To read X characters you can use read(X). This kind of method is rarely used though. You will mostly be reading the entire file (read() ) or one line at a time (  readline()  ).

Write a python program that renames a file?

Write a python program that deletes an existing file?

Write a python program that prints the current directory of the program?

Hint: 

“Current Working Directory” = cwd

Check the example on “creating folders/files” if you’ve forgotten this.

Write a python program that displays whether a file is properly closed or not?

Write a python program that displays in which mode the file is opened?

Write python program that takes the file name and type from the user and creates the file?

Write a python program that finds out the file extension from the file’s name?

Hint 1:

To get the file’s name recall that we can use file.name

Hint 2: 

You can split a string based on a character by using “any string”.split(“.”)
