def isAcceptableChar(character):
return charachter in "@&"
str = filter(isAcceptableChar, str)
is going to finally be what I am going to use.
I not feel lambdas are so readable, unless one has serious experience in
using them and python in general. I feel it is acceptable to add a named
method that documents with its name what it is doing there.
But your example would probably have been my choice if I was more
familiar with that type of use and the potential readers of my code were
also familiar with it. Many thanks!
Ben.
