I have a function like this:

def __init__(self, out_file='out.csv', tmp_folder=None):
 self.tmp_folder = tmp_folder if tmp_folder != None else join(getcwd(), '__tmp__')

I was wondering if ther exists a smarter way to do it, something like js:

 self.tmp_folder = tmp_folder || join(getcwd(), '__tmp__')

Since None evaluates to False, you could always do:

def __init__(self, out_file='out.csv', tmp_folder=None):
 self.tmp_folder = tmp_folder or join(getcwd(), '__tmp__')

Note however that this will assign self.tmp_folder to join(getcwd(), '__tmp__') if tmp_folder is any falsey value (False, 0, [], {}, etc.)

Yes, like this:

self.tmp_folder = tmp_folder or join(getcwd(), '__tmp__')

You just use or instead of ||
