Convert tuple to string after parsing html file
The issue is that each item in the list called urls is a tuple. A tuple is a container for other items and is also immutable. When you do item + " ", you are asking the interpreter to concatenate a tuple and a string which is not possible. What you want to do instead is inspect the tuple and select one of the fields in each item to write to the outfile: with open("1.txt", "w+") as outfile: f

Where do I place the validation exception code in my pyramid app?
1) Anywhere in your project directory. I made a new file called exceptions.py where I place all my HTTP status code and validation exceptions. I placed this file in the same directory as my views.py, models.py, etc. 2) That bad taste in your mouth is Python, because importing methods is the Pythonic way to go about using classes and functions in other files, rather than some sort of magic. Might

Using `raw_id_fields` to select related objects in the admin
It seems you've misunderstood how the link works. Django doesn't offer a selection for reverse foreign keys. From the Item admin you could select the Category like that. But not the other way around. One workaround would be to use a project that adds custom widgets such as Django Tags Input which adds a tag-like input field to your admin. In this case the configuration would look something like

Python, dynamically change the order of nested loops
Well, I usually conditionally assign to the target of the loops. You could also use an associative array containing the assignments. if SOMECONDITION1: target1 = js target2 = ks target3 = ls elif SOMECONDITION2: target1 = ks target2 = ls target3 = js elif SOMECONDITION3: target1 = ls target2 = js target3 = ks for j in js: for k in ks: for l in ls:

Flask RESTful Destroy User Token
Rather than a garbage token simply encode no data: def generate_auth_token(username=None, expiration=600): gen_serial = Serializer(secret_key, expires_in=expiration) data = {'username': username} if username is not None else {} return gen_serial.dumps(data) Then you can have an invalidate endpoint that requires a login and returns a token without a username: def invalidate(self):

Python Regex Match WillCard as the end of a word
That's probably because  is for word boundaries, not just characters. The following pattern will only give matches for what you initially specified (a word ending in * that doesn't have it in the middle or beginning) (?m)(?<!w|*)w+?*(?=[^w]|$) Works in RegexBuddy when tested against this string: word *word wo*rd word* *word* words Check for yourself If all you wanted was something to c

Is there a way to create key based on counts in Spark
How about using zipWithIndex? Zips this RDD with its element indices. The ordering is first based on the partition index and then the ordering of items within each partition. So the first item in the first partition gets index 0, and the last item in the last partition receives the largest index. This is similar to Scala's zipWithIndex but it uses Long instead of Int as the index type. This me

How can I embed two fields together in serializer
You can use a nested serializer to make this work. class FSerializer(serializers.Serializer): value = serializers.Field(source="f_value") metric = serializers.Field(source="f_metric") class MyModelSerializer(serializers.ModelSerializer): somefield = serializers.Field() f = FSerializer(source="*") This should give you the nested output you are looking for. You can find more inf
