Question

Say I have this piece of code, and I want to execute it on two separate dictionaries. How can I do this easily without writing the code twice? I guess i could def a small function and then pass each dict to it. Are there any better ways?

    for key, value in self.mfiles.iteritems():
        if key not in self.INPUT['extras']:
            self.mfiles[key] = self.dirs['confdir'] + '/' + value

    for key, value in self.nmfiles.iteritems():
        if key not in self.INPUT['extras']:
            self.nmfiles[key] = self.dirs['confdir'] + '/' + value

Answer 1

You can do this:

for data in (self.mfiles, self.nmfiles):
    for key, value in data.iteritems():
        if key not in self.INPUT['extras']:
            data[key] = self.dirs['confdir'] + '/' + value

However, I think writing a small function is probably clearer.
