New submission from Florent Xicluna:
I noticed a difference between computation of column offset for SyntaxError and
IndentationError (a subclass of SyntaxError).
It is slightly confusing.
def report(exc):
print('lineno %s, offset %s' % (exc.lineno, exc.offset))
raise
try:
exec('except IOError:')
except Exception as e:
report(e)
try:
exec(' open(filepath)')
except Exception as e:
report(e)
** OUTPUT **
lineno 1, offset 6
Traceback (most recent call last):
File "<stdin>", line 4, in <module>
File "<stdin>", line 2, in <module>
File "<string>", line 1
except IOError:
^
SyntaxError: invalid syntax
lineno 1, offset 4
Traceback (most recent call last):
File "<stdin>", line 4, in <module>
File "<stdin>", line 2, in <module>
File "<string>", line 1
open(filepath)
^
IndentationError: unexpected indent
** Analysis **
Case (1): offset is 6, and caret is below column 5 for SyntaxError
Case (2): offset is 4, and caret is below column 4 for IndentationError
