Your task is to do this completely and successfully. The program must run perfectly with out any errors. It must be efficient.
First off for context, here are the directions that were given:
Write a program to build a schedule for a small school. You will ultimately need to figure out:
A schedule for each student
A schedule for each teacher
A roster for each teacher’s sections
Whether or not we need to hire another teacher and what that teacher would need to teach
Scheduling Requirements:
Every full-time teacher teaches 3 classes per day
Every student takes all 4 of their classes every day
Section sizes →
Minimum: 5 students
Maximum: 30 students
A teacher may teach any course within their department, but no courses outside their department
Programming Minimum Requirements:
Make use of Python Dictionaries (key-value pairs)
Include a Student class with the defined functions:
__init__ → name, courses
set_name
get_name
add_courses
get_courses
You may add anything else you deem necessary
Include a Teacher class with the defined functions:
__init__ → name, courses, department
set_name
get_name
set_department
get_department
add_courses
get_courses
You may add anything else you deem necessary
For more context, here is the csv file titled Schedule Builder - Students.csv:

Мне нужно добавить поиск по локации. Причем, поиск должен быть "умным", так как чтобы не возиться с предустановленным городами, пользователь при регистрации может ввести собственное название города в свободной форме, я дал такую возможность. Нужно, сделать так, чтобы если пользователь ввел "масква", он по получил "Москва"

у меня есть прямоугольник разделенный на равные квадратики равноудаленными друг от друга линиями, как мне имея координаты точки в этом прямоугольнике определить в каком она квадратике? помести весь код в одну функцию lua, известно только количество rows, cols функция должна определять сама.

Мне нужно сделать так, чтоб при регистрации и поиске пользователь мог выбрать подходящий город, регион из json файла с городами, его примерная структура, cities.json:
[
{
"region": "Москва и Московская обл.",
"city": "Москва"
},
{
"region": "Москва и Московская обл.",
"city": "Абрамцево"
},
{
"region": "Москва и Московская обл.",
"city": "Алабино"
},
{
"region": "Москва и Московская обл.",
"city": "Апрелевка"
},
{
"region": "Москва и Московская обл.",
"city": "Архангельское"
},
{
"region": "Москва и Московская обл.",
"city": "Ашитково"
Сейчас у меня поиск организован по совпадению строк location.
Также город, регион должен отображаться в профиле

Мне нужно сделать так, чтоб при регистрации и поиске пользователь мог выбрать подходящий город, регион из json файла cities.json с городами, регионами. его структура такова:
[
{
"region": "Москва и Московская обл.",
"city": "Москва"
},
{
"region": "Москва и Московская обл.",
"city": "Абрамцево"
},
{
"region": "Москва и Московская обл.",
"city": "Алабино"
},
{
"region": "Москва и Московская обл.",
"city": "Апрелевка"
},
{
"region": "Москва и Московская обл.",
"city": "Архангельское"
},
{
"region": "Москва и Московская обл.",
"city": "Ашитково"
Сейчас у меня поиск организован по совпадению строк location.
Также город, регион должен отображаться в профиле

you are an data analyste expert since 20 years. You have measurements of thickness, with 49 pts per wafers, you actually follow the mean and the uniformity calculated by unif = (std/mean*100). there is other calculation to follow the uniformity stability
You need to monitor thichness deposition by following the resmap measurement on each matérial for a deposition tool on wafer.
Make a plan of what you need to put in place in order to have a good monitoring and stable process
Who many points of thickness measurement do you think we need, and which method to put in place to follow the thickness deposited across the all wafer, variability across the wafer, ...
make an example for 200mm wafers, on a SPC, you will precicely defined without asking "determine" or "specify" first the measurement protocol and after list all parameters you will follow on spc
with this a change of uniformity will change the mean, is it safe to process like this ? Or do we need to decorolate mean value on center vs uniformity across the all wafer ?

Make a accurate stock market predictor for predicting closing price using LSTM model and include super trend indicator for better results also make plot showing actual and predicted value (use dataset using yfinance for NIFTY):
Supertrend Indicator:
Super trend Indicator: What Does It Mean?
The Super trend indicator is a trend-following indicator that works just like moving averages. This indicator is typically represented by the price, and you can determine the latest trend by its positioning on the price. This basic indicator is designed by using only two parameters – multiplier and period.
The default parameters when you design the Super trend indicator plan are 3 for the multiplier and 10 for ATR (Average True Range). The ATR plays a crucial role here, as the Super trend indicator leverages the ATR for computing its value. It helps signal the degree or extent of price volatility.
Super trend Indicator: How Does It Work?
A super trend indicator is one of the most commonly used indicators for setting your selling and buying points at the most accurate levels. However, the question still remains: how does it work to accomplish something like that?
You should know that two lines – a green line and a red line – compose the Super trend indicator. These lines enable you to evaluate the following:
The trend direction,
Whether to buy or sell and, in either case, when to do so.
To plot and indicate the lines, the super trend indicator leverages the ATR along with the multiplicator. This enables you to set or position market entries based on volatility and momentum.
And when it comes to what chart is best for the Super trend indicator to function, you can independently utilize it on almost every timeline you consider a trend to be developing. A super trend is a lagging indicator, implying that any well-built trend will boost the indicator’s performance.
Super trend Indicator: Parameters to Know About
As you have read earlier, 10 and 3 are the two default parameters. You must remember that any modifications to these numerical values will influence the utilization of the Super trend indicator. No trading indicator comes with the best setting.
If you change more and more settings, the trading system may become over-optimized for that specific period. Keep a note of the following pointers:
The market noise will be removed with higher settings when there’s a risk of fewer trading signals.
The indicator will become more reactive/responsive to the price with smaller settings, resulting in more signals.
Super trend Indicator Formula
Here is the Super trend indicator formula that helps you calculate this indicator:
Down = [(High + Low / 2) – Multiplier] x ATR
Up = [(High + Low / 2) + Multiplier] x ATR
To calculate the ATR, follow this formula:
[(Previous ATR x 13) + Existing TR]/14
14 resembles a period in this equation. Thus, the ATR is determined by multiplying 13 by the past ATR. Then, add the result to the latest TR and divide it by the period. So, it’s clear that when it comes to the Super trend indicator, ATR plays a major role in it.
Super trend Indicator: How to Use It for Identifying Buy & Sell Signals
The super trend is an excellent trending indicator that functions exceptionally in both downtrends and uptrends. You can easily identify and locate the buy-sell signal whenever the indicator flips or rotates over the closing price.
When the super trend closes below the price point and the color changes to green, the buy signal is generated. Meanwhile, a sell signal is generated when the color changes to red and the Super trend closes above the price point

Представь, что ты программист Django. Нужно реализовать функционал сессий для юзера при помощи библиотеки
django-user-sessions:
урлы:
1) Просмотр всех сессий юзера.
2) Просмотр деталей конкретной сессии юзера (ip адрес, браузер и девайс, когда последний раз был активен, локация)
3) Удаление конкретной сессии юзера.
4) Удаление всех сессий юзера.
Представления нужно реализовать при помощи django-rest-framework.
Для логина пользователя я использую библиотеку dj_rest_auth.
Мое представление логина:
from dj_rest_auth.views import LoginView
class UserLoginAPIView(LoginView):
"""
Authenticate existing users using phone number or email and password.
"""
serializer_class = UserLoginSerializer
class UserLoginSerializer(serializers.Serializer):
"""
Serializer to login users with email or phone number.
"""
phone = PhoneNumberSerializer(read_only=True)
phone_number = PhoneNumberField(required=False, allow_blank=True)
email = serializers.EmailField(required=False, allow_blank=True)
password = serializers.CharField(
write_only=True, style={'input_type': 'password'})
class Meta:
model = CustomUser
fields = ('pk', 'email', 'phone', 'first_name', 'last_name')
def _validate_phone_email(self, phone_number, email, password):
user = None
if email and password:
user = authenticate(username=email, password=password)
elif str(phone_number) and password:
user = authenticate(username=str(phone_number), password=password)
else:
raise serializers.ValidationError(
_("Enter a phone number or an email and password."))
return user
def validate(self, validated_data):
phone_number = validated_data.get('phone_number')
email = validated_data.get('email')
password = validated_data.get('password')
user = None
user = self._validate_phone_email(phone_number, email, password)
if not user:
raise InvalidCredentialsException()
if not user.is_active:
raise AccountDisabledException()
if email:
email_address = user.emailaddress_set.filter(
email=user.email, verified=True).exists()
if not email_address:
raise serializers.ValidationError(_('E-mail is not verified.'))
else:
if not user.phone.is_verified:
raise serializers.ValidationError(
_('Phone number is not verified.'))
validated_data['user'] = user
return validated_data
Нужно при логине сохранять сессию юзера. При удалении сессии юзера нужно разлогинивать и убивать токен. Токен используется при помощи библиотеки dj_rest_auth - from dj_rest_auth.views import LoginView.

Make a accurate stock market predictor for predicting closing price using LSTM model and include super trend indicator for better results also make plot showing actual and predicted value:
Supertrend Indicator:
Super trend Indicator: What Does It Mean?
The Super trend indicator is a trend-following indicator that works just like moving averages. This indicator is typically represented by the price, and you can determine the latest trend by its positioning on the price. This basic indicator is designed by using only two parameters – multiplier and period.
The default parameters when you design the Super trend indicator plan are 3 for the multiplier and 10 for ATR (Average True Range). The ATR plays a crucial role here, as the Super trend indicator leverages the ATR for computing its value. It helps signal the degree or extent of price volatility.
Super trend Indicator: How Does It Work?
A super trend indicator is one of the most commonly used indicators for setting your selling and buying points at the most accurate levels. However, the question still remains: how does it work to accomplish something like that?
You should know that two lines – a green line and a red line – compose the Super trend indicator. These lines enable you to evaluate the following:
The trend direction,
Whether to buy or sell and, in either case, when to do so.
To plot and indicate the lines, the super trend indicator leverages the ATR along with the multiplicator. This enables you to set or position market entries based on volatility and momentum.
And when it comes to what chart is best for the Super trend indicator to function, you can independently utilize it on almost every timeline you consider a trend to be developing. A super trend is a lagging indicator, implying that any well-built trend will boost the indicator’s performance.
Super trend Indicator: Parameters to Know About
As you have read earlier, 10 and 3 are the two default parameters. You must remember that any modifications to these numerical values will influence the utilization of the Super trend indicator. No trading indicator comes with the best setting.
If you change more and more settings, the trading system may become over-optimized for that specific period. Keep a note of the following pointers:
The market noise will be removed with higher settings when there’s a risk of fewer trading signals.
The indicator will become more reactive/responsive to the price with smaller settings, resulting in more signals.
Super trend Indicator Formula
Here is the Super trend indicator formula that helps you calculate this indicator:
Down = [(High + Low / 2) – Multiplier] x ATR
Up = [(High + Low / 2) + Multiplier] x ATR
To calculate the ATR, follow this formula:
[(Previous ATR x 13) + Existing TR]/14
14 resembles a period in this equation. Thus, the ATR is determined by multiplying 13 by the past ATR. Then, add the result to the latest TR and divide it by the period. So, it’s clear that when it comes to the Super trend indicator, ATR plays a major role in it.
Super trend Indicator: How to Use It for Identifying Buy & Sell Signals
The super trend is an excellent trending indicator that functions exceptionally in both downtrends and uptrends. You can easily identify and locate the buy-sell signal whenever the indicator flips or rotates over the closing price.
When the super trend closes below the price point and the color changes to green, the buy signal is generated. Meanwhile, a sell signal is generated when the color changes to red and the Super trend closes above the price point.
