take it to another level

…Or add another level of exception handling

If you are a fan of the “handle exceptions as they occur” school of thinking, you’ll
simply wrap your code within another try statement.

Add another
“try” statement.
try:
data = open('sketch.txt')

for each_line in data:
try:
As with the
other program, (role, line_spoken) = each_line.split(':', 1)
all of this print(role, end='')
code remains print(' said: ', end='')
unchanged.
print(line_spoken, end='')
except:
pass

data.close()
Give the user except:
the bad news. print('The data file is missing!')

Another quick test is required, this time with the version of your program that uses exception handling. Press F5 to
give it a spin.
>>> ================================ RESTART ================================
>>> As expected, this version of the
The data file is missing! program handles the missing file, too.
