it should read:
open(file) do |fd
..process fd..
end
note that open() is defined as 'global' in ruby (in Object).
I think the closer match in python should be a method that perfomrs
what you wrote, and accepts a function in input. :
def do_open(name,fun):
fd=open(name)
try:
fun(fd)
finally:
fd.close()
