Algorithm : The following algorithm is used to display the exception that occurs in the code: • Initially, declare the “try” suite. • Declare the “float” function and pass the argument “abc123” into the function; then, initialize it to the variable “x”. ○ If exception does not occur in the “try” suite, then it displays that print statement. • Declare an exception named “IOError” to handle the non-existing files that may occur in the “try” suite. ○ Display a specified “IOError” except clause statement on the screen when “IOError” occurs in the “try” suite. • Declare an exception named “ValueError” to handle the non-numeric data passed as an argument in the “float” function that may occur in the “try” suite. ○ Display a specified “ValueError” except clause statement on the screen when “ValueError” occurs in the “try” suite. • Display the “end” statement after exception handled in a code.
