My favorite HTTP framework is Express.js because it is lightweight, flexible, and has a large ecosystem of middleware that makes it easy to build web applications and APIs quickly.
A JVM, or Java Virtual Machine, is an abstract computing machine that enables a computer to run Java programs by converting Java bytecode into machine code for execution.
In HTML / DHTML, U cant directly adding function. If u want
to use function in either PHP or JSP, U have to use
javascript.
Document.write("Message") It's the correct format
Either use (document.write) or use web technology like php

To extract the value it requires the object type to be defined and according to the object type only the values will be fetched. The values will be extracted as:
• If the object is a tuple then PyTuple_Size() method is used that returns the length of the values and another method PyTuple_GetItem() returns the data item that is stored at a specific index.
• If the object is a list then PyListSize() is having the same function that is defined for the tuple and PyList_GetItem() that also return the data items at a specified index.
• Strings uses PyString_Size() to return the length of the value and PyString_AsString() that return the pointer to its value.
• To check the type of the object and the extracted values use of methods like PyString_Check(), PyTuple_Check(), PyList_Check(), etc are used.
Django's working philosophy is based on the "Don't Repeat Yourself" (DRY) principle and the "Convention over Configuration" approach. It emphasizes reusability of components, rapid development, and a clean, pragmatic design. Django provides a robust framework that includes built-in features for handling common web development tasks, allowing developers to focus on building their applications efficiently.
To set up a database in Django, follow these steps:
1. **Install Database Driver**: Install the appropriate database driver for your database (e.g., `psycopg2` for PostgreSQL, `mysqlclient` for MySQL).
2. **Configure Database Settings**: In your Django project's `settings.py` file, update the `DATABASES` setting with your database configuration. For example:
```python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql', # or 'mysql', 'sqlite3', etc.
'NAME': 'your_database_name',
'USER': 'your_username',
'PASSWORD': 'your_password',
'HOST': 'localhost', # or your database host
'PORT': '5432', # or your database port
}
}
```
3. **Run Migrations**: Execute the following command to create the necessary database tables

2. In your Django project, open the `settings.py` file.
3. Locate the `DATABASES` setting and configure it with your database details. For example:
```python
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql', # or 'django.db.backends.mysql' for MySQL
'NAME': 'your_database_name',
'USER': 'your_username',
'PASSWORD': 'your_password',
'HOST': 'localhost', # or your database host
'PORT': '5432', # or your database port
}
}
```
4. Run `python manage.py migrate` to create the necessary database tables.
5. Optionally, create a superuser with `python manage
Python's built-in data type is dictionary, which defines one-to-one relationships between keys and values.
Dictionaries consist of pairs of keys and their corresponding values.
Dictionaries are indexed by keys.
Dictionary is similar to associative array or hash table of other languages.
As following example explains further- India, Angel & Cartoon are keys & their corresponding values are Bharat, Mother Teresa & Mickey respectively.
>>> dict = {'India': 'Bharat', 'Angel': ‘Mother Teresa’, 'Cartoon': 'Mickey'}
>>>print dict[India]
Bharat
>>>print dict[Angel]
Mother Teresa
