Exception Handling Exercises

Exception Handling

1. List the Python keywords used in exception handling and what they do:
2. Research 5 or more exceptions and what they do.
3. except-statements
   1. What is the maximum number of except-statements a Python script can have?
   2. What is the maximum number of except-statements that will execute?
   3. What is the minimum number of except-statements a Python script can have?
   4. What is the minimum number of except-statements that will execute?
4. finally-statements
   1. What is the maximum number of finally-statements a Python script can have?
   2. What is the maximum number of finally-statements that will execute?
   3. What is the minimum number of finally-statements a Python script can have?
   4. What is the minimum number of finally-statements that will execute?

5. By default, when a user pressing the control (CTRL) and "c" keys on the keyboard, a Python script will stop executing. Write a Python script that displays all of the numbers between 1 and 1,000,000. If the user presses CTRL-c, ask the user if they would like to continue. If they enter "y", have the script keep counting where it left off.

   Example:

   1
   2
   3
   ...
   ^C397046
   397047
   397048
   Would you like to keep counting (Y/N)? y
   397048
   397049
   ^C397050
   397051
   397052	    
   Would you like to keep counting (Y/N)? n
   Have a nice day!

Error Checking and Exception Handling

1. Discuss with someone else the major differences between error handling and exception handling.
2. Should you always use error checking (if-statements) instead of exception handling?
3. Give an example of when to use error checking instead of exception handling.
