Because there aren't any. When you read lines from a file there will always
be at least the newline character. Otherwise it would indeed fail:
>>> for line in "peter\npaul\n\nmary".splitlines():
... print line.upper() + line[1:]
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
IndexError: string index out of range
