Hi pythoners. I am generating strings of length n, randomly from the symbols
+-/*0123456789 What would be the 'sensible' way of transforming the string, for example changing '3++++++8' into 3+8 or '3++--*-9' into '3+-9' such that eval(string) will always return a number? in cases where multiple symbols conflict in meaning (as '3++--*-9' the earliest valid symbols in the sequence should be preserved so for example, '3++*/-9' = 3+-9 '45--/**/+7' = 45-+7 '55/-**+-6**' = 55/-6 ...that is, unless there is a canonical method for doing this that does something else instead.. this sounds like homework. It's not. I like making problems up and it's a slow work day. So, as an aside, there is no real reason I want to do this, nor other problem to solve, nor other background to what I'm trying to achieve ;) other than twiddling with python. Matt.
