Question

[Dag Hansteen]

>>> s = "2+2"
>>> answer = int(str(s))
Traceback (most recent call last):
  File "<pyshell#64>", line 1, in ?
    answer = int(str(s))
ValueError: invalid literal for int(): 2+2

How do I this ? I have a string with a such expression and I want to return the answer in a variable.

Regards Dag Hansteen
