code to protect

You were to study your program and circle the line or lines of
code that you think you need to protect. Then, in the space
provided, you were to state why.

data = open('sketch.txt')

for each_line in data:
(role, line_spoken) = each_line.split(':', 1)
print(role, end='') These four
print(' said: ', end='') lines of code
print(line_spoken, end='') all need to be
protected.

data.close()

If the call to “split()” fails, you don’t want the three “print()”
statements executing, so it’s best to protect all four lines of the “if”
suite, not just the line of code that calls “split()”.

OK. I get that the code Yeah...good point. It’s
can be protected from an probably best to ignore
error. But what do I do when it, right? I wonder how...
an error actually occurs?
