Re: [Python-ideas] Reuse "for" to express "given"

But I do have a mathematics background, and I don't remember ever seeing "for x = value" used in the sense you mean.

That's so because in mathematics, "for" is spelled ":" as in {2*a* : *a*∈*Z*} If you can read the above, you should not have trouble reading {2*a* + *b* : *a*∈*Z *: *b = *1}
