New submission from Bnaya <[email protected]>:
I was writing the following:
re.search('([+-*])', "54 * 83")
And I got the following runtime error:
Traceback (most recent call last):

re.error: bad character range +-* at position 2
Note that for different operators order, such as:
re.search('([+*-])', "54 * 83")
or
re.search('([*+-])', "54 * 83")
the function worked just fine.
