fa = Fa.objects.filter(fa_name = tag)[0]
It was working in python 2.7 and django 1.8 but now that I migrated to django 2.2 and python 3.6 its not working
If you want to get the first if no data then None you should use first method:
fa = Fa.objects.filter(fa_name = tag).first()
It will return you None if you have no data and if you do have then it will return the first element
If you want to avoid any None values then you should check before executing it:
if Fa.objects.filter(fa_name = tag).count() > 0:
fa = fa = Fa.objects.filter(fa_name = tag)[0]

My code seems to bring up an Attribution error when I run it- AttributeError: 'list' object has no attribute 'strip'
This is the detail of my code
# 'dataset' holds the input data for this script
from textblob import TextBlob
from textblob.exceptions import NotTranslated
def translate_comment(x):
try:
# Try to translate the string version of the comment
return TextBlob(str(x)).translate(to='en')
except NotTranslated:
# If the output is the same as the input just return the TextBlob version of the input
return TextBlob(str(x))
dataset['new_translation'] = dataset['review_comment_title'].apply(translate_comment)

Dictionary:

Error says:
3
So how come the date key works fine but for freq it fails?
ps. my first time posting, so am very sorry for the sloppy structure of the post
This can only happen when one of your day is missing the freq parameter.
Try catching the day in which the error is happening. Then manually check that particular entry.
date_list = []
frequency_list = []
try:
for i in obj:
date = obj[i]["date"]
frequency = obj[i]["freq"]
date_list.append(date)
frequency_list.append(frequency)
except:
print(i)

I want to check if the "nilai" is None/Null
cursor.execute('SELECT s.kode_ktg_id,(SUM(n.nilai_angka * S.nilai_mk)/SUM(s.nilai_mk)) as nilai_ktg FROM mahasiswa_khs k, mahasiswa_convert_nilai n, mata_kuliah_si s WHERE k.nilai = n.nilai_huruf AND k.nim = "%s" AND k.kode = s.kode GROUP BY s.kode_ktg_id',[nim])
nilai = cursor.fetchall()
I check with this
if nilai[0] is None:
But I got error tuple index out of range
This is because nilai is an empty tuple, since it returned no records.
You can check if it is empty with:
if not nilai:
# no records
else:
# at least one record
That being said, in Django you can make use of the Django ORM, which is often safer, and wraps elements in model objects.

How do I make a REST query in python with a comparison statement? Like (in quasi code):
result = foo where bar > 10
I want to make a rest api query from python 2.7 using requests. What I want is to get all articles that have been updated during the last 24 hours.
In javascript it looks like this and it works great:
http://myDatabase.domain.io/api/v1/article/q={"update_date":{"$gt":"2018-08-27 13:44"}}
I just can't recreate this with python. Does anyone know how?
Assuming
that's actually ?q=, i.e. a query string
and the query should be JSON (it looks like it)
and the endpoint returns JSON:
import requests, json
query = json.dumps(
{"update_date": {"$gt": "2018-08-27 13:44"}}
)
resp = requests.get(
url="http://myDatabase.domain.io/api/v1/article/",
params={"q": query},
)
resp.raise_for_status()
data = resp.json()
print(data)

I am kinda new to working with json and python and I am stuck on the parsing the data in js to generate an expression. I would really appreciate anyone suggestions on the best path to take.
Here is the Data I am working with
{"statuses":[{"metadata":{"result_type":"recent","iso_language_code":"en"},"created_at":"Fri Dec 06 15:06:44 +0000 2013","id":408975801577926656,"id_str":"408975801577926656","text":"RT #jk636575: #GhanaNudes contact me if you want to swing\njk636575#gmail.com","user":{"id":974873810,"id_str":"974873810","name":"Gh Nudes","screen_name":"GhanaNudes","location"
Here is my code:
def main():
ts = TwitterSearch()
response, data = ts.search('#gmail.com', result_type='recent')
js = json.loads(data)
messages = ([data_items] for msg in js)
I need to parse the content in js and turn it into a generator expression so that I only write: Created_at , text , user:{is
Based on the Twitter search API docs,
messages = ([msg['created_at'], msg['txt'], msg['user']['id']] for msg in js['statuses'])
Note that I have updated my answer to the original question to include this.
Edit: It might be a bit safer to replace in js['statuses'] with in js.get('statuses', []).
