parsing equations

[munehiro]

hi all,

i have a question.
Given the string '3+2*6' i need to parse it and obtain the result, so
15. Does a module for this operation exists? i need to do simple
operations, but also on floating point numbers.

many thanks

Use the builtin function eval to evaluate an arbitrary python expression:
15

15

Be aware that this is powerful:
'done'

Just to make sure the OP is aware of the inherent danger of the unsuspecting
"arbitrary python expression"...

Yup - should have mentioned that.
